Engineering & Build Highlights

N+X modular scalability allows hot-swapping power modules without interrupting the critical server load
Unity output power factor delivers 100% real kW power to modern power-factor-corrected server loads
Cold start capability allows starting the UPS and powering loads directly from batteries during a blackout
Integrated dual input feeds (separate Mains and Static Bypass supply lines) for maximum distribution security
Lovato BCE automatic switch-mode battery chargers maintain backup batteries at optimal float charge
Complete battery temperature compensation prolongs VRLA battery life in tropical Kenyan climates

Target Applications & Sectors

Data centres, server rooms & internet service providersHospital operating theatres, ICU wards & life support systemsBanking transaction servers, ATMs & financial trading floorsTelecommunication cell towers & fiber optic transmission hubsIndustrial automation PLC racks & SCADA control roomsBroadcast studios & security surveillance control rooms

Line-interactive UPS systems take 4 to 10 milliseconds to switch to battery during a blackout, which can crash sensitive servers and medical equipment. Online double-conversion constantly converts AC to DC and back to AC, delivering seamless 0ms transfer time and perfectly clean sine-wave output.

High-quality VRLA AGM batteries typically last 4 to 6 years if ambient room temperature is maintained below 25°C. Lithium LiFePO4 batteries offer 10 to 15 years design life and withstand ambient temperatures up to 35°C without rapid degradation.
