Electromagnets must be able to release ferrous objects as readily as they attract and hold them. Release is the function of the Power Supply – not the magnet. Power Supplies render a reverse current that ensures positive release of even those alloy steels that retain induced magnetism extremely well. All Bunting® Power Supplies are designed to provide D.C. power for industrial electromagnets.
Note: Total wattage of all magnets powered by a single Bunting Power Supply must not exceed the wattage rating of the Power Supply. For example, one to five 3-watt magnets can be used with a 15-watt Power Supply.
