AU (Automatic Release) Rectifier Controller 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 or "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, operator judgment 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.

Electromagnetic Chuck Controls

The SD Series automatic controls are used when greater chuck demagnetization is required and for those chucks with high wattage ratings. The main enclosure can be located at the rear of the machine or wall mounted. The chuck is operated from a small remote control unit
(4-1/2" x 6-1/2"x 4") located at the front of the machine which includes the "ON-OFF" control switch, red and green indicating lamps and the variable power control. The green lamp indicates the chuck is ready to accept or remove the part. The red lamp indicates the chuck is magnetized. When the control switch is turned off, the red lamp diminishes in intensity until it goes out leaving only the green lamp on. The operator can then remove the part with ease. The variable power control provides 0 to 100% power.

The NT and MA Series can also be used to operate smaller electromagnetic chucks where a single pulse release cycle is adequate.
