Salicru UPS Dubai. You're Probably Paying 25% More for UPS Protection Than You Need.
Most online UPS systems carry a power factor of 0.8. That means a 10kVA unit only delivers 8kW of real power. Every Salicru SLC UPS carries PF=1 — the kVA you buy is the kW you get. Same load. Same protection. Lower cost. We'll show you the numbers.
The Number Nobody Explains
Your 10kVA Online UPS Might Only Be Delivering 8kW
When you buy a double conversion UPS in Dubai, the headline number is kVA — 6kVA, 10kVA, 20kVA. What most suppliers don't explain is that kVA is not the same as kW. The difference between them is the power factor.
Most online UPS systems carry a power factor of 0.8. That means a 10kVA UPS delivers 10 × 0.8 = 8kW of real power to your servers and equipment. To protect a load of 10kW, you need to buy a 12.5kVA unit — the next tier up, at a higher price.
The core Salicru SLC range — the TWIN RT3, CUBE4, and ADAPT2 — carries an output power factor of 1. That means the kVA rating and the kW capacity are the same number. A 10kVA Salicru SLC CUBE4 delivers 10kW of real power. No gap. No hidden shortfall. No reason to buy the next size up.
The Same 10kW Server Room Load — Two Different Purchases
The input power factor also matters for your building. The Salicru SLC CUBE4 has input PF > 0.99 — it draws almost no reactive power from the building's electrical supply. For a data centre or server room on a commercial DEWA contract, reactive power draw can create penalties. A near-unity input power factor means the UPS is invisible to your upstream electrical infrastructure.
This is why Salicru's online UPS range costs what it does. Not because the components are more expensive. Because you need fewer of them.

What the Spec Sheet Doesn't Say
Eight Things Worth Knowing Before You Buy an Online UPS in Dubai
These are the engineering decisions that determine how a double conversion UPS performs in UAE conditions over five years — not on a European test bench on day one.
The SLC CUBE4, CUBE3+ and ADAPT2 use three-level NPC inverter topology with 4th-generation Trench Gate IGBT technology. Two-level topology switches at the full DC bus voltage on each cycle. Three-level topology switches at half that voltage, producing lower heat, lower stress on the semiconductors, and significantly cleaner output.
For a Dubai server room or data centre running blade servers, virtualised infrastructure and switching power supplies — the load is non-linear. Three-level topology produces output THDv below 0.5% on linear loads and below 1.5% on non-linear. Clean enough that equipment running from the UPS receives power cleaner than the grid typically provides.
The result: lower heat inside the inverter, longer component life, and output quality that sensitive electronics prefer.
Every online double conversion UPS draws current from the building's electrical supply. Most draw it in pulses that create harmonic distortion — THDi of 10–30% is common. That harmonic current flows back through the building's neutral cable, through the distribution transformer, and through every other device sharing the same supply.
Harmonic current in neutral cables causes them to run hot — sometimes above their rated capacity. It reduces transformer efficiency and rated load capacity. It can trip sensitive protection circuits.
The Salicru SLC CUBE4 has input THDi confirmed below 3% at rated load. The three-phase IGBT full-wave rectifier with PFC draws current continuously and smoothly. The UPS draws power as if it were a perfectly linear, resistive load. Your building's electrical infrastructure never knows a large UPS is there.
The moment most businesses discover their UPS battery has failed silently is the moment the power cuts. The UPS switches to battery — and the battery lasts 3 minutes instead of 15. By then it is too late.
Every Salicru SLC CUBE4 includes Batt-Watch — a continuous battery management system that monitors health across the full charge cycle, adjusts charging voltage and current based on temperature and battery age, and generates advance warnings as degradation is detected. It supports VRLA, lead-acid, gel, Ni-Cd, and lithium-ion — all chemistries.
The UAE-specific problem: at 35°C ambient, a sealed lead-acid battery ages roughly twice as fast as it would at 25°C. A 5-year rated battery may fail in under 3 years in a Dubai plant room. Batt-Watch measures the actual degradation rate, not the calendar date. The UPS tells you. The outage doesn't have to.
The question a data centre operations team eventually faces: the load has grown beyond the current online UPS capacity. A new module is required. The server room cannot go down. The UPS cannot go to bypass.
The Salicru SLC ADAPT2 modular UPS is built for exactly this moment. Each power module has its own independent rectifier, inverter, battery charger and DSP controller. When you slide a new module in from the front panel during live operation, the cabinet controller detects it, runs self-test, and begins sharing the load automatically — in full view of the protected equipment, which never experiences a voltage variation.
Front-panel extraction means no rear-access cable clearing in a live rack. A module can be removed and replaced in minutes without tools and without touching a cable run. MTTR (mean time to repair) drops from hours to minutes. For a server room or data centre in Dubai that cannot afford a maintenance window — this is the architecture.
A facilities manager with UPS systems across three commercial buildings in Dubai has the same problem every time: each UPS needs a separate site visit to check status, and the first sign of a battery problem is usually the beeping alarm at 2AM.
NIMBUS is Salicru's IoT monitoring platform — free, no subscription, no licence. It uses MQTT protocol, runs on an embedded Linux NIMBUS card in the UPS, and communicates via the native Ethernet port or optional WiFi. Every unit in your account is visible on one screen: real-time load, battery state of charge, input and output voltage and frequency, alarm status.
Push notification the moment anything is outside normal parameters. Remote battery test without a site visit. 40-day alarm log. Integration into any existing building management or DCIM platform via standard protocols. SSL encryption with the client's own digital certificates. The UPS fleet monitors itself — you get notified when something needs attention, not when it fails.
Your DEWA commercial electricity bill has a line that many operations managers don't fully understand: the demand charge. It is calculated based on the highest power draw recorded at any 15-minute interval in the billing month. One afternoon when everything was running simultaneously — the HVAC, the production line, the servers — set that peak and determined the demand charge for the entire month.
The Salicru SLC CUBE3+ PS three-phase UPS includes a built-in peak shaving function. You set a maximum grid consumption threshold — any value between 10% and 100% of your load requirement. When total demand exceeds that threshold, the UPS automatically discharges its battery to keep grid draw at or below your set point. When demand drops, the battery recharges.
The demand charge on your DEWA bill is capped by design, not by chance. A UPS that pays through your electricity bill every month — not only through the cost of the outage it prevents.
UAE electrical supply runs at 50Hz. A meaningful portion of industrial and laboratory equipment imported from North American markets is rated for 60Hz. Running 60Hz equipment on 50Hz supply reduces motor speed, changes timing-sensitive processes, and can cause overheating in equipment designed for 60Hz cooling fans.
The Salicru SLC TWIN RT3 online UPS supports a dedicated frequency converter mode. Input at 50Hz, output at 60Hz. Or input at 60Hz, output at 50Hz. One unit provides both power conditioning and frequency conversion simultaneously — eliminating the need for a separate rotary or static frequency converter.
Note on sizing: output power is derated in frequency converter mode — a 5kVA unit delivers approximately 2kVA in this mode. Correct load assessment before ordering is important. We advise on this case by case — WhatsApp us the equipment load and we confirm the right SLC TWIN RT3 model.
An online UPS system running 24 hours a day in full double-conversion mode consumes power even when the grid is stable. The SLC CUBE4 achieves over 96% efficiency in online mode — already excellent — and over 99% in eco mode, where the inverter stays in warm standby and the load passes through with the inverter ready to take over in milliseconds if the supply degrades.
For facilities with a diesel generator: the Salicru three-phase UPS range is confirmed generator-compatible. The UPS bridges the 4 to 8 seconds between grid failure and generator startup — providing clean, uninterrupted power throughout. Once the generator is stable, the UPS transfers load to generator supply automatically. When the generator switches off and grid is restored, the UPS again absorbs the transition, preventing the transients from reaching connected equipment in either direction.
For a Dubai industrial facility or hospital running both grid and generator — this is the complete power continuity solution without additional hardware.
Two Types of UPS Buyer
Your Server Room or Your Building — Both Need a Different Conversation
An IT manager protecting a rack of servers in a Dubai office has different concerns from a facilities manager protecting three-phase industrial equipment on a 400V supply. The Salicru SLC range covers both — but the right starting point depends on which problem you are solving.
Your servers need a rack-mount UPS that fits, performs, and doesn't beep at midnight
Your server rack is in a standard 19-inch cabinet. Depth matters — the cable runs behind the UPS need space to breathe. The SLC TWIN RT3 online UPS was designed for exactly this constraint: 2U height, only 600mm depth, with variable-speed dual fans managing heat front-to-rear without noise.
It protects IT servers, voice and data networks, ERP systems, CRM platforms, document management systems and video streaming infrastructure. True online double-conversion — the output is generated entirely by the inverter, isolated completely from grid disturbances and frequency variations. Your servers receive cleaner power from the UPS than from the grid.
The lithium-ion version — SLC TWIN RT2 LION — runs for 10 years without battery replacement. Lithium-ion delivers 10x the discharge cycles of standard VRLA at the same size and performs reliably up to 40°C, meaning your plant room temperature doesn't affect battery life the way it does with sealed lead-acid. For a server room UPS in Dubai that you don't want to think about for a decade — this is the specification.
IoT monitoring native: the SLC TWIN RT3 has a built-in Ethernet port and optional WiFi. NIMBUS app shows every unit in your account on one screen. Push notification on any alarm. Remote battery test without visiting the room.

SLC ADAPT2 · 10–600kVA · Hot-swap modular · Data centre scale
Your three-phase UPS needs to handle the load, the generator gap, and the DEWA bill
If you're on three-phase 400V supply — a commercial building, manufacturing facility, hospital, hotel, or industrial operation — the three-phase online UPS requirement is more complex than kVA sizing. You need a unit that handles unbalanced loads across phases, bridges cleanly to your generator, and doesn't inject harmonic distortion back into your building's electrical infrastructure.
The Salicru SLC CUBE4 (7.5–80kVA) and SLC CUBE3+ (7.5–200kVA) address all three simultaneously. PF=1 output means you size to the actual kW load, not to 125% of it. THDi below 3% means your neutral cables, distribution transformer and protection relays are unaffected. Generator compatibility is confirmed across the range.
The SLC CUBE3+ PS variant adds active peak shaving — the UPS monitors your DEWA grid demand continuously and discharges the battery when demand approaches your set threshold. For a commercial building in Dubai paying a monthly demand charge, this function reduces that charge every billing cycle.
For data centres or facilities that need to expand UPS capacity without a maintenance window, the SLC ADAPT2 modular industrial UPS scales from 20kVA to 600kVA in a single cabinet, with hot-swap modules that can be added during live operation.

UAE Installation
Three Things That Are Different About UPS in Dubai
European UPS specifications are written for 20°C ambient temperatures, predictable grid quality, and VRLA batteries that achieve rated lifespan. Dubai is different on all three counts. Here is how the Salicru SLC range addresses each.
Heat and Battery Life
VRLA battery capacity degrades faster at elevated temperatures. At 35°C ambient — common in UAE plant rooms and electrical rooms — a battery rated for 5 years in a 25°C environment may require replacement in under 3 years.
The SLC TWIN RT2 LION uses lithium-ion batteries rated for operation up to 40°C, delivering 10× the discharge cycles of VRLA at the same form factor. The SLC CUBE4's Batt-Watch system monitors actual battery health continuously — not estimated remaining life based on calendar date. For any chemistry: you are warned before failure, not by it.
Grid Quality and Phase
UAE single-phase supply is 230V at 50Hz. Three-phase commercial supply is 400V (3×400V) at 50Hz. Every Salicru SLC model we supply is CE-specified for these parameters.
The SLC CUBE4 and CUBE3+ input voltage range is +15% / −20% configurable — the UPS accepts supply variations between 184V and 264V (phase to neutral) before switching to battery. For UAE commercial properties where grid voltage can fluctuate during peak demand periods, this wide input tolerance means the battery is used only when the grid actually fails — not during every voltage dip.
DEWA Tariffs and Demand Charges
DEWA commercial tariffs for medium and large premises include a monthly demand charge based on peak power consumption. One high-demand event — all HVAC, servers and production running simultaneously — sets the demand charge for the entire month.
The SLC CUBE3+ PS three-phase UPS includes a built-in peak shaving function with an adjustable demand threshold. When total load approaches your set limit, the UPS discharges the battery to keep grid draw at or below the threshold. Every month. Without manual intervention. The UPS pays through the electricity bill reduction, not only through the downtime it prevents.
IoT Monitoring · Free
Your UPS System Monitors Itself and Calls You When Something Is Wrong
The standard arrangement for UPS monitoring in Dubai is: wait for the beeping alarm. Then find out the battery is at 20% because the grid has been unstable all week. Then find out the battery was already degraded before that. The Salicru approach is the opposite — the system tells you before any of this becomes a problem.
NIMBUS Cloud
NIMBUS is Salicru's free IoT monitoring platform for the SLC UPS range. One account manages every unit you own, anywhere in the UAE. Real-time load, battery state of charge, input and output voltage, frequency, and alarm status — visible from your phone or browser without a site visit.
Push notification the moment any value moves outside normal parameters. 40-day alarm log with full event history. Remote battery test from anywhere — confirm battery health without sending an engineer. OTA firmware updates delivered over the air to installed units.
NIMBUS uses MQTT protocol and runs on an embedded Linux NIMBUS card installed in the UPS. It integrates into any existing BMS or DCIM platform. SSL encryption with the client's own digital certificates — not stored on a third-party cloud account you don't control.
Batt-Watch
Batt-Watch is the battery management system built into every SLC CUBE4. It monitors battery health across the full charge and discharge cycle, not just at the end of each cycle. It adjusts charging voltage and current based on actual battery temperature and measured impedance — not a calendar-based estimate.
For a UPS system in Dubai where ambient temperature accelerates battery aging, Batt-Watch provides the one thing that prevents the most common failure mode: discovering the battery is weak only when the power cuts. It supports all battery chemistries — VRLA, lead-acid, gel, Ni-Cd, and lithium-ion. Upgrade path to lithium-ion is available without replacing the UPS.
When battery degradation is detected, NIMBUS sends a push notification. You replace the battery on your schedule, not in response to an outage. That is the difference between a maintained UPS system and an unmonitored one.
60 Years of Critical Infrastructure
The Engineering Protecting Your Server Room Also Protects These
Salicru was founded in Barcelona in 1965 — before APC existed, before Eaton entered power electronics. For six decades the company has built industrial UPS systems for environments where power failure is a safety event. The same engineering principles applied to railway signalling and hospital infrastructure are applied to the SLC commercial range.
Haramain High-Speed Railway
Salicru SLC CUBE3+ and SLC ADAPT2 UPS systems protect the Operations Control Centre and signalling infrastructure along the Mecca–Medina high-speed rail corridor — over 400 kilometres of track serving millions of annual pilgrims. In this environment, UPS failure is not a server restart. The same double conversion UPS engineering is in your server room.
AVE High-Speed Rail Network
Over 100 Salicru units — including SLC ADAPT2 and SLC CUBE3+ — protect control systems, signalling equipment and switching points across the Madrid–Sevilla line for its 30th anniversary upgrade, plus installations on Madrid–Barcelona, Barcelona–Figueres, Córdoba–Málaga, and Segovia–Valladolid corridors. Proof from deployments, not from brochures.
Live Data Centre Reference
Six SLC ADAPT2 modular UPS units currently provide backup power for all IT infrastructure and ancillary services at a 4MW data centre in Sant Cugat del Vallès, Barcelona — with 8MW expansion capacity designed in. All managed remotely via NIMBUS. Same architecture, same monitoring, available for your data centre in Dubai.
Additional installations: Santo Domingo Metro Line 2 (Dominican Republic) — over 1 million daily passengers. FGC railway interlockings across Catalonia, Spain. Cairo–Alexandria rail corridor, Egypt. Turkey high-speed rail. This is not a product that was built last year.
