A Polaron Cortina 7,000 Amp rectifier offering a thryristor controllable 0-60 Volt output.
Cortina specialise in the manufacture of Variable voltage and current thyristor rectifiers, for anodising, welding and plating applications.
The Polaron Cortina is a primary SCR, single copper wound transformer, DC power supply that was originally employed for a plating/brightening anodizing application.
The Polaron Cortina rectifiers SCR diodes are water cooled allowing it to be used in warmer climes compared to the more traditional UK air cooled units.
