The Standard series of Air-Cooled Rectifiers provide an economical alternative to the Custom and Automatically controlled rectifier lines.







Combining a lighter gauge enclosure with a chassis pan method of component layout results in a cost-effective rectifier. Incoming AC power is stepped down, isolated and rectified to a controlled DC output. Input-overload and short-circuit protection are provided by magnetic-trip breakers; output protection by means of one-time fuses in the transformer secondary. Primary AC/DC surge protection and secondary surge protection provided by disk-style M.O.V’s. Output control using 25-steps of tap adjustment, gives ample control to output settings. A single meter, switched between amperes and volts, is supplied as standard construction, with extra meters available optionally. The Standard series of rectifiers has made available a basic, economical rectifier for cost effective cathodic protection systems.
