Our
Power UPS is designed specially for power station , substation. With the function of time delay switching between line and zero . It is mainly used for the areas where loads need high requirements for voltage . When the mains power supply is normal , Single phase **0V AC through isolation , and supply power for inverter after rectifier filter , if AC input power off , the inverter will be supplied power by the own DC screen of power system via defence of the diode, then to provide power for important loads through output isolation , if DC screen power off , the system will be still supplied power by AC input , if inverter overload or fault , the system will switch to BYPASS power supply via static switch .
Application fields : Operation of electric system , communication , power carrier , power monitoring UPS of Power station , substation , power distribution etc areas .
Performance characteristics ♦ Adopting Mitsubishi fifth generation efficient IPM module ♦ Adopting microchip high efficient DCP ♦ Power down protection of the Mains supply : The power will be supplied by the system own DC screen if AC input power off to protect uninterrupted ouput ♦ Improving power supply quality : Output stable standard pure sine wave , not effected by the Mains supply ♦ Noise inhibition : Adopting isolation transformer and AC-DC-AC transformation , effectively filter out noise wave in the ac input ♦ Soft state : With the function of soft state , so as to reduce the impact to equipment and power grid during the process of system startup ♦ Communication terminal : RS***2/**5?support MODBUS protocol ♦ Real-time data record , can record all the tested data and fault state . ♦ Can query history record .
