Product principle
  SKEPS series three -phase EPS emergency power supply, which provides emergency power supply equipment for all 380/220V electric appliances and equipment such as first -level load, important load, fire protection facilities, fire emergency lighting or other load, can be used as a second or second or second or secondaryThree power supply.
  When the city electricity is normal, the municipal electricity passes through the mutual investment device to power the load. At the same time, the charger is intelligently charged for the spare battery.When the city's electricity breaks or 20%of the normal voltage, the controller provides a inverter signal, starts the inverter power supply, and at the same time, the mutual investment device will be immediately cast to the inverter power output, and the sine wave AC power will be continued.After the electric voltage is normal, the emergency power supply will automatically restore the power grid power supply.
Features
1. CPU control, pure pioneering wave output;
2. Use the smart IPM module to output balance and stability;
3. Applicable perceptual load and hybrid load;
4. It has protection functions such as over pressure, pressure, temperature, overcurrent, and short circuit;
5. Smart battery charging management functions can realize the automatic conversion of floating charging, effectively extend the battery life;
6. Automatic conversion, can achieve no one on duty;
7. Energy saving, not power consumption during emergency.
