Heavy Duty Transformer Based Battery Charger
Heavy Duty Battery Charger Secondary cells once exhausted, need to be charged by DC source having a voltage current characteristics to match the one specified by the battery manufacturer. 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 VARIAC - continuously variable voltage auto transformer. DC output is electrically isolated form AC input. These battery chargers are designed and made to customer''s individual specifications which vary widely.
