DC Rectifiers

These DC power rectifiers and Power supply rectifiers find application in industries, particularly - Electroplating, Anodizing, Hydrogenation and other electrochemical processes. Our range of custom designed DC Power Rectifiers and DC Power supply rectifiers is available in the capacities ranging from 200 A to 15000 A at different output DC voltage.

Starting Circuitry
DC Rectifiers are designed for 3 phase 50 Hz. These rectifiers are most suitable for voltage fluctuations from 380 and 440 volts. We can also custom design Power Rectifiers for 60Hz and the required voltage specifications. It is recommended to connect the input to the rectifier through a proper protective device, to provide positive protection to personnel and the system, in the event of maintenance or in case a fault occurs.

DC Output Control
DC Output control is used to control voltage or ampere current or its operating range by varying input voltage to the main transformer. The DC output voltage variation can be achieved by means of an On Load roller type power make voltage regulator.

Specific Features
Few of the specific features of our Electroplating Rectifiers that makes them highly efficient and reliable include the following:

Designed for 100% Continuous Duty Cycle
Compact Design for Space Saving
Lesser Power Consumption
Negligible Maintenance
Tested at Each & Every Stage of Manufacturing
Trouble Free Service
