Westinghouse Air cooled heavy duty silicon diode 500 Amp 20 Volt transforming rectifier with inbuilt Variac stepless control .
Predominantly used in the electro plating, electro forming, electro paint, electro polishing and motor control industries, to provide a stable DC current supply.
These units is fitted with Variac regulating transformers to the incoming supply to give stepless variable voltage output.
These units can be mated to matching rectifiers in series or parallel to offer and output of either 1000 Amps at 20 Volts or 500 Amps at 40 Volts respectively.
Low ripple D.C. over the full operating range.
Designed for reliable service and continuous duty.
Economic operation by virtue of high efficiency copper transformer coils.
Regulating transformer, mains transformer, silicon-stack, overload and thermal protection devices, copper bus-bar connection and multi tap input connector are all mounted on a sturdy steel frame within the self contained rectifier cabinet.
Good air circulation through the silicon stack, mains transformer, and other components is achieved by an open base, canopy top, cabinet design.
Bus-bar terminations for the rectifier pass through insulated supports positioned in the top, or rear, to suit individual requirements.
The rectifiers are suitable for crane and fork-lift transport.
A.C. Input 3 x 380V, 3 x 400V, 3 x 415V, 3 x 440V +/- 5% 50Hz 19Amps
Standard rectifiers are suitable for continuous duty in an ambient temperature of up to 35°C provided the rectifier is sited to allow free air circulation and at a maximum height of 1000 M above sea level.
Standard rectifiers: 5% or better over the full range of operation.
