The Leviton OPP20-D2 is a 20 amp power pack for Leviton's line of occupancy sensors. It contains both a 24VDC power supply input/output and a load switching latching relay. A power pack provides Class 2 low-voltage power to the occupancy sensors while also minimizing wear and tear on relay contacts.

This Leviton occupancy sensor power pack features many different mounting options. It can be placed outside or inside a 4x4 junction box or inside or outside of a ballast cavity of a light fixture. The choice of installation depends on desired application.

Leviton power packs feature cost-effective and simple energy management. This model features many on and off capabilities, including automatic on/off through an occupancy sensor or photocell input and manually through an optional low voltage switch. Multiple occupancy sensors can be connected to one power pack, for full area coverage.
