The A-type control block allows you to control the thyristors (SCR) of the rectifier bridge with the implementation of the following modes of operation of cathodic protection devices:
- automatic stabilization of the CP rectifier output current;
- automatic stabilization of the protective potential;
- manual adjustment of the device output current (voltage).
Also, the A-type control block can be used as a control unit of any thyristor single-phase rectifier.
