Power Pack and
Auxiliary Relay — 120V/ 277V
The power pack supplies low voltage power to Schneider Electric ceiling and wall mounted occupancy sensors,
and employs a heavy duty 20A relay to switch lighting and HVAC loads based on a control signal received from
the occupancy sensor. The power pack accepts 120V and 277V input and supplies up to 100mA at 24VDC.
The power pack employs a micro-controller that switches loads at minimum voltage, protecting relay contacts
from high in-rush 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 relay does not supply power, but switches lighting and HVAC loads based
on a control signal from the occupancy sensor.
Both the power pack and auxiliary relay are housed in a rugged plenum rated enclosure, and rated for lighting
and HVAC loads, including electronic ballasts. Flexible mounting scheme allows for installation inside or outside
a standard 4 x 4 inch junction box.
