Introduction

DPS-175 is designed to be used with the Electromagnet, Model: EMU-75 as a constant current power supply to generate magnetic field upto 11KG. The current requirement of 3A per coil, i.e. a total of 6A was met by connecting six closely matched constant current sources in parallel. In this arrangement the first unit works as the ‘master’ with current adjustment control. All others are ‘slave’ units generating exactly the same current as the master. All the six constant current sources are individually IC controlled. One advantage of this arrangement is that if a particular constant current source develops a fault, still the remaining channels would continue to operate albeit with a reduced maximum current capability. The supply is protected against overload, short circuit and transients caused by the load inductance.
