Thyristor Controller

This is a thyristor control board with phase angle regulation.
With a minimum of external components, it allows for AC control and control of a bridge rectifier.
The most important characteristics are:
– Controls up to 6 thyristors, in W3C or B6C connection.
– 3x400V power supply without neutral.
– Automatic phase balancing.
– Input of a 60mV shunt signal.
– Voltage and current regulation.
– Auxiliary power supply outputs for instruments
