This is High frequency rectifier used for 15kA 15V electroplating rectifier application in hard chrome plating.
Type of circuit: 5 modules parallel connection. In each module, three phase AC input is converted to DC through rectification and filter, then DC voltage is transformed to DC output through phase shift full bridge PWM DC/DC converter, shown below diagram.
IGBT high frequency rectifier, modular structure, easy for maintenance
Rated Output: DC
380V AC +-10% 3 phase 4line, 50Hz
Output regulation range
Constant current/constant voltage selectable
100% 24 hours continuous running
Audible and visual alarm
For Enclosure and main circuit board components
Yes.After power resuming the power supply to the rectifier,
Insulation grade: B
B means allowed temperature rise than ambient temperature is 130℃)
Cooling water requirement:
resistivity ≥20KΩcm, hardness<8 dH
Water is not corrosive, dirty or contains acids.
Inlet Water Temperature
To prevent condensation, the water must not be too cold. The ideal temperature is between ambient temperature and 35℃(not below dew point)
Inlet Water Pressure
