Manual
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 ensures positive release of even those alloy steels which are magnetically retentive. Variable power and remote control are available. Rectifiers and rectifier-controllers are designed to provide reliable D.C. power for industrial electromagnets and electromagnet chucks.

Automatic
AU (Automatic Release) Series: AU Series Rectifier Controllers, with solid state circuitry, provide the rapid cycling and quick, clean release necessary for high speed automated magnetic equipment. Ideal for robotics and "pick and place" applications.

D.C. magnet control is accomplished by means of an A.C. input signal or pilot switch. The pilot switch or signal source can be a considerable distance from the rectifier without introducing a voltage drop in the magnet circuit.

A SPST switch, limit switch, or PLC output can be used to operate the rectifier. When a manual switch is used, operatorjudgment is not required to "Time Out" the release cycle because the cycle is completely automatic. An adjustable, timed pulse of reverse current to the magnet effectively releases the load.

Enclosures are J.l.C., oil-tight and non-ventilated.
