The RPC series proportional controllers
provide a cost effective method of con-
trolling power in many different appli-
cations such as heaters, universal
motors or incandescent lamps. A cus-
tomer provided potentiometer is all that
is required for control. All modules are
supplied with KS100 protective cover.

GENERAL NOTES
All parameters at 25C unless otherwise specified.
Off-State dv/dt test method per EIA/NARM standard RS-443, paragraph 13.11.1
Heat sinking required, for derating curves see page 2.
Potentiometer should be selected with regards to line voltage isolation.
W ARNING
Control to load is not isolated, excercise care in handling the
RPC products to avoid the risk of electric shock.
