EPS Emergency power supply

Emergency Power Supply

EPS is an emergent power supply which provides power guarantee and fire protection for concernful buildings. CYKE Series of EPS is used abroad in building eletric field and special emergent power supply situation. It’s principle is as following: when AC grid is normal, it gives power to concernful loads through convert devices. While it is cut off, power supply converts to EPS immediately. And power supply turns to AC grid again while it recovers normal in order to avoid life hurt and estate loss in disaster.

CYKE Series of EPS technology features:

  • Inverter module uses MCU controlled SPWM technology, pure sine wave output

  • Unique dynamic current-loop control technology to ensure reliable operation of inverter

  • Strong load-suit capacity, including capacitive, inductant and mixed load

  • Strong over-load capacity, and can withstand the computer’s full load boot

  • High-power bypass switch, bypass power supply when overload

  • Over-voltage, under-voltage, over-temperature, over-load and short circuit protection, etc.

  • LCD and LED double display on front panel, clear status

  • High efficiency(no eletricity cost when EPS off), low noise, no smoke, no fire hidden trouble

  • Auto convert and off-duty

  • Stable performance, on the safe side and long use-life.
