PHS SERIES
Phase Control
Description
The PHS Series is an ideal method of changing lamp intensity,
varying the speed of a fan/motor, or controlling the temperature
of a heater. The effective output voltage is adjusted with an
accessory external potentiometer suitable for line voltage
applications.
Operation
Upon application of input voltage, effective output voltage
can be varied by changing the external resistance value. As
the external resistance increases, the effective output voltage
decreases. The inverse is also true.
