The Corrpro® VAYS variable transformer series of air-cooled rectifiers provides a low-cost alternative power source for smaller cathodic protection installations. Combining a compact enclosure with anessentially infinite number of output settings, this rectifier series is an ideal choice for utility and gas distribution systems.
Incoming AC power is stepped down and controlled by the variable transformer and rectified to a controlled DC output. Input-overload and short-circuit protection is 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 MOVs. Single meter (switched between amperes and volts) supplied as normal construction with extra meters is available as option.
