Industrial UPS - 5KVA to 300KVA

We provide isolation Transformer as a seperate part, wherever necessary to the senstive loads from abnormal input , which is highly increased the life of the load / equipments.

For three-phase output application, we import the basic module. Along with that we supplies other items like Bypass line equipment & Distribution board manufactured by us, Batteries procured from domestic battery vendors & integrate the system at site.

Special Features

  • True online double conversion design
  • IGBT inverter and output isolation transformer
  • Accurate synchronized utility system
  • Static bypass, allows system to be bypassed for maintenance operations
  • Allow 100% unbalance load
  • Double DSP control
  • 3x2 redundancy logic power design
  • Wide input voltage range
  • DC cold start function
  • Full protection function (short circuit, overload, over temperature, low battery etc)
  • Intelligent RS232/RS485 and dry connection interface, and flexible net project for monitoring via SNMP adapter (option)
