Electromagnet Model Emu-75 And Dps-175m

We are well known for manufacturing, exporting and supplying top quality assortment of Electromagnet Model EMU-75 and DPS-175M in Roorkee, Uttarakhand, India.
We manufacture Electromagnet, EMU-75 which has the most widely used a Ua shaped soft iron yoke. The soft iron is of a special quality, structurally uniform, well machined and finished to meet the rigid standards. The air-gap is continuously variable upto 75mm with two way knobbed wheel screw adjusting system. Normally flat pole pieces are supplied. Tappered pole pieces can be supplied on special request.

The coils are wound on non-magnetic formers with uniform layers of S.E. copper wire. The new and modern design of the coils provides good thermal conductivity characteristics and eliminates troublesome hot spots even at high magnetic fields.

Specifications of Electromagnet are as follows:
Field Intensity: 11KG at 10mm air-gap with flat pole pieces
Pole Pieces: 75mm diameter
Energising Coils: Two, each having a resistance of about 12IC
Power Requirement: 0-90Vdc, 3A, if coils are connected in series.
0-45Vdc, 6A, if coils are connected in parallel
Weight: 81Kg

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 a mastera with current adjustment control. All others are a slavea 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.
