The company starts with testing and re-insulating the Power Transformer in varnish. Thyristors (SCR’s) and Diodes are tested and replaced when weak or imbalanced. Heat sinks are cleaned and surfaced finished to manufacturer specifications. Firing boards, regulator boards, and control circuits are updated to new. Safety features such as DC Overloads, single phasing protection, thermostats and fuses are replaced. Each rectifier is wired to new manufacturing standards. Each rectifier is fully load tested prior to shipping. Units are shipped with correct wiring diagrams, lists of components and instructions. Rectifiers are available from stock in both air and water cooled designs.
