BKH Series Modular 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
Front panel for easy maintenance, inlet wire from top to bottom for easy connection by user
Large touch screen of human-machine interface, a great amount of information
Independent charging system, strong charging capacity, Perfect battery management scheme
Parallel connection technology of digital modules, precision circular current index
Easy to install even close to other equipments, space-saving footprint in service room
Redundancy and intelligent adjustable-speed fan, low noise, low power consumption
Integrated distribution system inside system cabinet, easy to install, low investment by user
Good matching performance with motor
DC Starting via battery (cold boot) for easy operation
Three-proofing treatment of all circuit boards.
Optional Standard battery bank or extension battery bank
