The rectifier construction of the production series RGB-Thyro-Power in principle
is characterized by an electronic Thyristor-control-unit (W3C) and
high-current-transformer with secondary connected silicon diode-stack
in M3.2U connection.

All constructions and developments are made by RGB-Heythekker, so that the
customer will get the highest possible flexibility and technical know-how.
This is realized with our high degree of own manufacturing, including the
RGB transformer production.
