This is 500A12V Polarity Reversing Rectifier For Electrocoagulation Waste Water Treatment.
Automatic reversal, polarity reversal time: +-10 min-30 min.
IGBT technology, Modular design.RS485 communication.
Europe quality with CE Standard, China price.
IGBT Rectifier Working Principle
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.
Touch Panel HMI Operation
(1) Communication status
(2) Output DC current and voltage and AmpereHour counting display
(3) Timer counting display
(4) N for reversal time setting
(5) Running status display
Running: always red-Stopped status, green flash-running
Alarm: gray-no protection, red flh-there is protection
(6) Running mode display
Control Mode: Local control or Remote control
Output Mode: Constant Voltage or Constant Current
Reverse Time Setting
The power supply will run at forward or reverse output based on setting time.
Set the polarity reversing running time:
(1) If set Positive Time and Negative Time- both to 0, it will run at always forward output.
(2) Positive Time+ and Negative Time- setting time could be different
(3) Positive Time+ and Negative Time- settable time range: 1-60000S.
