Nvis 725B DC Regulated Power Supply is an important device mainly used in electrical engineering laboratories for the purpose of conducting experiments in DC Machines and circuits. This unit provides Fixed and Variable DC output for continuous operation with an over current protection. Output voltage and current are continuously monitored on two 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 to the DC Machines. All the protection devices are inbuilt for protection purpose.
