The CC-PP1277 and CC-PP1347 power packs supply low voltage power to CRISTAL ceiling and wall-mounted occupancy sensors. They can switch lighting and HVAC loads based on a control signal received from the occupancy sensor.

The power packs employ a micro-controller that switches loads at a minimum voltage, protecting relay contacts from high inrush current common when switching electronic ballasts. This switching method reduces the stress across the relay contacts, preventing arc-over and assuring long reliable contact life. Similar to the power pack, the auxiliary relays do not supply power, but switch lighting and HVAC loads based on a control signal from the occupancy sensor.

The CC-PP1277 model employs a heavy-duty 20A relay, accepts 120V and 277V input and supplies up to 100mA at 24VDC. The CC-PP1347 model uses a 15A relay, accepts 347V input and and supplies up to 150mA at 24VDC.
