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.
Zero delay transform between the city electricity power supply and the DC inversion power supply.
AC input, DC input and AC uninterruptible output are completely isolate.
High stable and precise voltage output
Large load ability
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.
