REL 3131-IND 10-80KVA

The REL3131-IND system is composed of power special-purpose UPS, DBW bypass regulator cabinet, PDU series feeder cabinet. Reliability REL3131-IND system is developed specifically for mission-critical facilities eg. power plants, substations, power distribution products are designed with online double conversion, zero conversion function. Main applications including electric power long distance, RT U, power carrier wave, power monitoring and so on. When the utility power is normal, three phase 380V After isolation, rectification and filtering through the inverter to provide a stable power supply to the load; if the input AC power is abnormal or power failure, the backup power system by the D C screen provide power supply through non-return diode inverter. When the DC screen occurs voltage shortage or power break, the static switch transfer to bypass for power supply; When the electricity is restored, the inverter automatically switches to utility power and provide power supply under inverter mode. If the inverter overload or fault and transfer power supply under bypass mode, also give a warning signal at the same time.
