Product Description

Nvis 725A DC Supply is used in electrical engineering laboratories for the purpose of conducting experiments in DC Machines and Circuits. This product provides 200V Fixed and Variable DC output for continuous operation with an over current protection. Output voltage and current can being continuously monitored by front panel meters. The main power assembly consists of a thyristor bridge circuit which rectifies the incoming AC supply to produce a Fixed DC supply. Rectified voltage can be varied by altering the firing angle of the thyristors thereby providing Variable DC Output to the DC Machines.
