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. Features & Benefits FEATURES BENEFITS External adjustment - 230VAC rated potentiometer Allows control of heavy loads directly, solid state design will provide long life Up to 20A steady state - 200A inrush Allows control of heavy loads directly, solid state design will provide long life Single hole surface mounting Provides quick and easy installation Accessories P1004-174 (100kΩ 1W), P1004-175 (200kΩ 2W) Versa-Pot Panel mountable, industrial potentiometer recommended for remote time delay adjustment. P0700-7 Versa-Knob Designed for 0.25 in (6.35 mm) shaft of Versa-Pot. Semi-gloss industrial black finish. P1015-64 (AWG 14/16) Female Quick Connect These 0.25 in. (6.35 mm) female terminals are constructed with an insulator barrel to provide strain relief.
