IMS has designed a series of low cost miniature unregulated switchers and
unregulated linear supplies that can handle varying load conditions. This
makes them ideal for stepper motor drives and DC servo motors as well. Each
of these is available in either 120 or 240 VAC configuration. See the IMS
Catalog or website
(www.imshome.com
) for information on these supplies.
Listed below is the power supply recommended for use with the IB462H.

In the event that you are manufacturing your own interface for the IB462H you
will need to 5VDC to power the logic circuitry inside the hybrid.

Interfacing to the IB462H,
will contain PCB layout guidelines
and precise details on po5VDC.

Noise is always present in a system that involves high power and small signal
circuitry. Regardless of the power configuration used for your system there are
some wiring and shielding rules that should be followed to keep the noise-to-
signal ratio as small as possible.
R u l e s o f W i r i n g
Power supply and motor wiring should be shielded twisted pairs run
separately from signal carrying wires.
A minimum of 1 twist per inch is recommended.
Motor wiring should be shielded twisted pairs using 20-gauge wire
or, for distance greater than 5 feet, 18 gauge or better.
Power ground return should be as short as possible to established
ground.
Power supply wiring should be shielded twisted pairs. Use 18
gauge wire if load is less than 4 amps, or 16 gauge for more than 4
amps.
