Phase Control
PHS Series
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.
For more information see:
Appendix B, page 165, Figure 4 for dimensional drawing.
Appendix C, page 172, Figure 40 for connection diagram.
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.
