Uninterrupted Power Supply (UPS)

Uninterrupted Power Supply (UPS)

Product introduction:
  Electric power exclusive use online UPS is a new power supply which is especially designed for power plant and transformer substation, with online, zero delay transform function, it is mainly used where the load need good voltage, for example: electric power telemechanics, RTU, DCS system, electric carrier wave, supervision and so on.
Product features.     

 using Standard Screen Cabinet with Power Design.
Zero-delay conversion between utility electric Supply / DC inverter power .
Using DSP digital control technology, intelligent detection and monitoring capabilities.
 High-speed IGBT drive inverter.
 Passive monitoring of contacts and RS232/485.
 With overvoltage, low voltage, overcurrent, short circuit protection functions .
 big-screen English LCD, perfect display, interface-friendly.

Principle:
   When the city electricity is natural, the single phase AC220V or triphase 380V through isolation, commutation, wave sieving, and supply the inverter, If the AC input is broken, the battery cell will supply the inverter through the inverse proof diode, then through the output isolation and supply the important load. If the battery cell is broken, the AC will input and supply the power. If the inverter is overload or broken, the side circuit will supply the power through static state switch
