DESCRIPTION The Series EPC phase angle controller has an analog input isolated from the mains to vary the phase angle proportionally to the input and load voltage. The EPC phase angle controller is designed mainly for resistive loads. The EPC may be used with inductive loads, but with limitations. It provides internal protection from load transients. The conduction level is controlled by the input. The Series EPC provides an external adjust that allows the user to modify the cycle time for any particular application. 3.26 (82.7) .17 (4.4) 1.57 2.89 (40) (73.5) APPLICATIONS • Lighting control (light dimming) • Single-phase motors • Heating control (regulation) TYPICAL APPLICATION 3.58 (91) L1 L2 3.94 (100) WEIGHT: 14.46 oz.
