Electricity professional UPS are designed for power plants, substations, Power distribution Centers, with dual exchange-line and zero conversion function. Mainly used for RTU, power monitoring. When main supply is normal, power of single-phase 220V (or three-phase 380V), after isolation, rectification, filtering through the inverter, provide stable power supply to the load.

When the DC screen is under voltage or power fails, it switches to bypass power supply; When electricity is restored, the inverter automatically switches to main supply. If the inverter overload or fails, it switches to bypass power supply and gives an alarm.

Input voltage: 380Vac,384Vac,432Vac,480Vac,528Vac/3phases; 

Output voltage: 220Vac,230Vac,240Vac,380Vac,384Vac,480Vac/3phases available or 120Vac, 220Vac,230Vac,240Vac/1phase available

Battery voltage: 125Vdc,216Vdc,220Vdc, 380Vdc,384Vdc, 432Vdc, 480Vdc available; Batteries can be with lead acid batteries or nickel cadmium batteries
