Lithonia PP20 Power Pack - Relay Circuit Protection 120/277 Vac PP20

Intended use power pack - relay circuit protection features dual voltage transformer self-contained relay patented relay contact protection (tested to over 400k cycles) powers up to 14 sensors listings ul and cul listed construction power packs are the heart of the low voltage sensor system. The pp20 transforms 120 240 or 277 volts to class ii 15 vdc to power the remote sensors. Optics n/a electrical with the sensors connected the red and black wires provide dc power to the remote sensors and when there is occupancy detected the white wire produces a 15 vdc signal from the sensor back to the power pack initiating the lights to "on". Installation mounting 1/2" knockout in fixture or junction box
