High-efficiency 3-phase power protection engineered for data centres, hospitals and industrial automation
Nairobi Power Engineers provides enterprise-grade three-phase Online Double-Conversion UPS systems ranging from 10 kVA standalone tower units to 800 kVA modular parallel configurations. Certified to IEC 62040-3 VFI-SS-111, our UPS systems isolate critical equipment completely from utility power sags, surges, brownouts, and frequency shifts.
With three-level IGBT inverter topology, unity output power factor (kVA = kW), and efficiency up to 96.5% in double-conversion mode (and 99% in ECO mode), our UPS systems reduce electrical operating costs while maximizing data centre and hospital uptime.
Modular Architecture • N+X Redundancy
High-density modular UPS chassis with hot-swappable 25 kW / 50 kW power modules, decentralized control logic, and built-in static bypass.
Monolithic Industrial • High Inrush
Robust transformer-based and transformerless monolithic UPS systems designed for harsh factory environments, motor inrush loads, and medical scanners.
