The CPS15330 cathodic protection rectifier range is our series of high current oil cooled type transformer rectifiers with manual control of the output voltage by variable autotransformer or by tapchanger switch. Full wave output rectifiers give low ripple and high short-term capacity. The transformers and rectifier bridge are oil cooled in a separate section of the rectifier tank.

The D5546 system take a 3 phase AC supply and adjust it by either a primary toroidal 3phase variable transformer or by a primary tap changer transformer. Variable auto transformers give3 continuous adjustment from 0 - 100% of output and primary tap changer transformers have the adjustment ranges with sensible voltage steps. The adjusted AC voltage is then supplied to a 3 phase load transformer and stepped down to a low voltage. The load transformer uses high quality grain oriented core steel and copper windings to reduce losses. The low AC voltage is passed through a full wave diode bridge and to the output terminals. Conservative design of the rectifier bridge, combined with a choice of transformer configurations, keep rectifier efficiency high and temperature rise low.

Available 05-200Amps maximum and also as per requirement
