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.
