Electromagnets require direct current power for operation. Whether used in manual or automated handling of ferrous parts, they must release the work as readily as they attract and hold. Release is a function of the rectifier and not the magnet. These rectifiers incorporate a provision for reverse current that insures positive release of even those alloy steels which are magnetically retentive. Variable power and remote control are available. Magnetool rectifiers and rectifier-controllers are designed to provide reliable D.C. power for industrial electromagnets and electromagnetic chucks.

MA Series – Heavy Duty Usage

The MA Series rectifier controllers are designed for heavy duty use and feature an oil-tight enclosure, an isolation transformer with dual voltage single phase input and a customer accessible terminal connection strip. All units utilize a 3 position toggle type control switch (On-Off-Release) mounted on the enclosure. Variable power and remote control options are available. Consult factory for custom applications.
