Transformer Rectifier

Transformer RectifierCathodic Protection rectifiers are designed for protection of underground metal constructions such as pipelines, oil wells against soil/electrochemical corrosion. CP rectifiers are suitable to adopt all kinds of reference electrodes, like Zn, Ag/AgCl, Cu/CuSo4 electrode.· Constant Volts/Amps/Ref Potential· Single and 3 phase power input · Rugged electronic control High voltage rated devices· Relatively easy to protect from lightning transients· Milliamps to thousands of amps output current· Soft start on power-up or after interruption· OFF to ON  - suits DCVG surveys on pieplines· Optional remote controlAir-cooled transformer rectifier specifications:  Item ParameterSingle PhaseThree PhasePWM SwitchMounted TypePortable typeFrequency50Hz~60Hz50Hz~60Hz50Hz~60Hz50Hz~60Hz50Hz~60HzAC Input Voltage220V380V220V220V220VDC Output Voltage(variable)DC 0~50VDC 0~100VDC 0~50VDC 0~50V  DC 0~50VDC Output Current0~50A0~300A0~80A0~40A0~20ACurrentlimiting0~30A0~200A0~60A0~30A0~15ASet potential0~±3V0~±3V0~±3V0~±3V0~±3VConstant potential precision≤5mV≤5mV≤5mV≤5mV≤5mVConstant current precision≤1%≤1%≤1%≤1%≤1%Input Impedance﹥5MΩ﹥5MΩ﹥5MΩ﹥5MΩ﹥5MΩRipple≤3%≤3%≤3%≤3%≤3%Surge ArresterConfiguredConfiguredConfiguredConfiguredConfiguredWorking StyleContinuousContinuousContinuousContinuousContinuousIP Protection(Optional)IP 54~IP 66IP 54~IP 66IP 54~IP 66IP 54~IP 66IP 54~IP 66AC Noise Immunity≥24V≥24V≥24V≥24V≥24VRemote Data Transmission & Remote controlOptionalOptionalOptionalOptionalOptionalCircuit StructureModularizationModularizationModularizationModularizationOil-cooled transformer rectifier specifications:  Item ParameterSingle PhaseThree PhasePWM SwitchMounted TypePortable typeFrequency50Hz~60Hz50Hz~60Hz50Hz~60Hz50Hz~60Hz50Hz~60HzAC Input Voltage220V380V220V220V220VDC Output Voltage(variac)DC 0~50VDC 0~100VDC 0~50VDC 0~50V  DC 0~50VDC Output Current0~50A0~300A0~80A0~40A0~20ACurrent limiting0~30A0~200A0~60A0~30A0~15ASet potential0~±3V0~±3V0~±3V0~±3V0~±3VConstant potential precision≤5mV≤5mV≤5mV≤5mV≤5mVConstant current precision≤1%≤1%≤1%≤1%≤1%Input Impedance﹥5MΩ﹥5MΩ﹥5MΩ﹥5MΩ﹥5MΩRipple≤3%≤3%≤3%≤3%≤3%Surge ArresterConfiguredConfiguredConfiguredConfiguredConfiguredWorking StyleContinuousContinuousContinuousContinuousContinuousIP Protection(Optional)IP 54~IP 66IP 54~IP 66IP 54~IP 66IP 54~IP 66IP 54~IP 66AC Noise Immunity≥24V≥24V≥24V≥24V≥24VRemote Data Transmission & Remote controlOptionalOptionalOptionalOptionalOptionalCircuit StructureModularizationModularizationModularizationModularizationModularizationThe power rating of the above mentioned transformer rectifier was optional from 500w to 30Kw.
