The PHPM-PA-DV-WH is a phase-adaptive power module, provides capability for zone on a GRAFIK Eye control unit to dim fully loaded circuit of lighting. May be used to control incandescent, electronic low-voltage, magnetic low-voltage, and neon/cold cathode lighting sources, as well as Lutron Tu-Wire fluorescent dimming ballasts. Automatically selects leading-edge or trailing-edge dimming for low-voltage transformers. Provides power and dimming for one zone. Up to 3 power modules may be wired on a single GRAFIK Eye zone. 120V control voltage, 120 to 277V load voltage and 16A/1920 to 4432W capacity. Not for use with non-dim loads. 50/60Hz frequency, phase-to-neutral. Phase independent of control device/control voltage. Indoor use only. 135BTU/hour maximum heat output of module. Surface or recess mounting. UL tested.

Automatically selects between forward phase/leading edge (e.g., magnetic low-voltage) and reverse phase/trailing edge (e.g., electronic low voltage) dimming/output based on connected load. Patented RTISST circuitry compensates in real time for incoming line voltage variations, compensates for +/-2% change in RMS voltage/cycle and +/-2%Hz change in frequency/second. Provides air-gap off. Module protects itself during most temporary overcurrent and over-voltage conditions. Two LEDs on front of unit provide diagnostic information (visible when faceplate is removed). Each terminal accepts up to two 12AWG wires.
