Air Cooled Rectifier:
Secondary cells once exhausted, need to be charged by DC source having a voltage current characteristics to match the one specified by the battery manufactures. The mains supply voltage is stepped down and rectified by using a bridge connected rectifier to produce the desired output for charging the batteries. Output is adjustable within a limited range either in small steps, using one or more rotary switches or smoothly, using a VARIPAC - continuously variable voltage auto transformer. DC output is electrically isolated form AC input.

Specifications :
Air Cooled Rectifier are designed and made to customer's individual specifications which vary widely. Broad specifications which cover most of the application are:

• Input: 240 V, 1 phase or 415 V, 3 phase, 50 Hz AC
• Output: Upto 300 V DC
• Capacity: Upto 400 Amps.

Salient Features :

• Air Cooled Construction
• Suitable for indoor / outdoor applications
• Fully tropicalised
• Liberally designed components and adequately derated diodes

Metering :

• Indicating meters to monitor DC voltage and/or current
• Integrating meter on input side to monitor the energy consumption

DC Motor Drives :
These are used for running DC shunt motors from AC mains at one or different sppeds, for details ask for our data sheet on Motor Control Panel.
