Magnetic Separator Accessory

D.C. Supply is required for the excitation of the magnet coils. A suitable transformer and rectifier is needed for each Electro Magnet. Switching ON/OFF is done on the three phase/A.C. side of the rectifier. By this kind of connection no additional protective measures against voltage peaks are required which arise by the high inductivity of the magnet when switching off.

The rectifiers and the three phase current motors are dimensioned for 415V/50Hz. The units can also be supplied for other voltages and frequencies, on request.

Elektromag manufactures and supplies appropriate accessories such as Transformer Rectifier Sets and Control Panels to provide DC Power supply to the Magnets and AC power to the Drive Motors used in Magnetic Separators.
