BKH SERIES MODULAR UPS
Category: UPS
BKH Brief
BKH series modularized UPS maintains the technical features of traditional tower-type UPS and adopts modularized design to meet the need of modern service room, while ensuring the high reliability of the system. BKH series offers various power modules and cabinet systems, and the user can able to flexibly combine them according to load demand. The capacity of a single cabinet is 200KVA and that of combined cabinets reaches 400KVA.
BKH Main Features
- UPS system is modular design, N+X redundancy, hot plugging for system update or capacity expansion
- Strong load adaptability and loading capacity, and excellent power grid applicability
- Green and energy-saving power supply; overall efficiency>95%, input power factor> 0.99, input current harmonics (THDi) <3%
- Dual DSP for independent control of power module, no single point of failure
- Digital control of rectification, inverter, charging and discharging via DSP
- Integrated and packaged IGBT instead of discrete device to greatly enhance the reliability of power module and UPS system
