Water cooled thyristor rectifie
The basic design of the water cooled rectifiers is characterized by electronic thyristor primary controller (W3C) and high-current transformer with downstream silicon diode set in a 6-pulse circuit. All designs and developments are carried out in-house, so that the customer can be offered a maximum of flexibility. This is perfected by the high vertical range of manufacture, including in-house winding production for transformers and chokes.
