Explosion protected rectifier
Thyristor-Rectifiers particulary suitable for EX-zone.
The rectifier construction of the production series 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 or B6C connection.
All constructions and developments are made by IPS-FEST, 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 transformer production.
