Electric supply UPS is specially designed for power plant, transformer station, with online, zero delay switch protection, mainly used in the fields of high demand to load such as electric telemechanism, RTU, DCS system, electric carrier wave, monitor etc.

Products features:
1. Between Utility supply and DC inverter zero switch
2. Absolute isolation among input AC, DC input and AC uninterrupted output
3. High voltage stability precision output
4. Strong carry load capacity

Principle:
When the utility power normal, isolate the monophase AC of 220V (triphase 380V ), supply the power for the inverter by rectifier filter, if the Ac input cut off, the DC screen of provided for itself of the electric system supply power for the inverter through against converse diode, Supply the power supply for the mainly load by output isolation, if the DC screen cut off, still have the AC input power supply, if the inverter over load or fault, have the static switching change into bypass power supply.
