The LPCV Linear Proportional
Controllers control loads up 110
Amps. Changes in the input signal
linearly vary the firing angle of the
thyristor load control device. Control
circuitry and power switch are in the
same package. The PS-120 (120V)
and PS-240 (240V) power supplies are
designed for use with the LPCV con-
troller to provide the 20Vac required
in addition to the control voltage.
