PHS SERIES

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.
