Reversible programmable inverter rectifiers designed to be supplied by rectified unidirectional or bi-directional current.

Performed functions

The rectifier provides the following functions:

✓ Automatic stabilization of the output current setpoint

✓ Rectifier within PCS on Modbus RTU protocol, RS485 interface

✓ Separate setpoint of ​​output current stabilization for the forward and reverse directions;

✓ Automatic reversal of the current for the separate setup of pulses duration in forward and reverse direction;

✓ Unipolar pulse current with a separate setup of pulse duration and pause;

✓ Light indication:

Operation modes;

Outages;

✓ Digital display on the LCD touchscreen:
