Leviton OSP20-RDH Occupancy Sensor Power Pack
The Leviton OSP20-RDH is an occupancy sensor power pack designed to interface between line-voltage lighting circuits and low-voltage occupancy sensor controls. As a core component in Leviton's occupancy and vacancy sensing lineup, the power pack provides the switching and relay function that allows wall- or ceiling-mounted sensors to control connected lighting loads. Electrical contractors and facility managers rely on power packs like the OSP20-RDH to complete an occupancy sensing circuit where low-voltage sensor wiring needs to be isolated from and interfaced with the building's line-voltage wiring.
Key Features
- Occupancy Sensor Interface: Functions as the power pack/relay module that connects low-voltage occupancy sensors to line-voltage lighting circuits.
- Leviton Engineering: Manufactured by Leviton, a recognized name in commercial lighting control and occupancy sensing systems.
- Model OSP20-RDH: Identified by Leviton as an OCC Sensor Power Pack within their occupancy control product family.

Leviton OSP20-RDH – Frequently Asked Questions
1) What does a Leviton OSP20-RDH power pack actually do in an occupancy sensor circuit?
The OSP20-RDH is the interface between a building's line-voltage lighting circuit and a low-voltage occupancy sensor. The sensor itself doesn't switch the load; it sends a low-voltage signal, and the power pack carries the relay that opens and closes the line-voltage circuit feeding the lights. It also isolates the low-voltage sensor wiring from the line-voltage side, which is why it is a required piece rather than an accessory on most low-voltage sensor installs.
2) Do I need a power pack if I'm installing a low-voltage Leviton occupancy sensor?
Yes. A low-voltage sensor has no means of switching the lighting load on its own, so it needs a power pack like the OSP20-RDH to provide the relay and to keep the sensor wiring isolated from the line-voltage circuit. Self-contained line-voltage wall switch sensors are the exception, those replace the switch directly and don't use a separate pack.
3) Is the OSP20-RDH a complete occupancy sensing solution or do I have to order sensors separately?
It's the interface module only. The OSP20-RDH supplies the relay and low-voltage interface; the wall- or ceiling-mount occupancy sensor that actually detects presence is a separate item, as is any additional control wiring. Plan the order as a pack plus one or more compatible Leviton sensors for the space.
4) What is the exact Leviton part number to specify for this occupancy sensor power pack?
Order it as Leviton OSP20-RDH. That single model is the whole offering, there are no finish or voltage variants to pick, so the catalog number on the drawing and the number on the carton are the same thing.
5) Can a power pack like this be used on a retrofit, or is it new construction only?
Both. Power packs get used in new lighting control rough-ins and in retrofits where an existing line-voltage lighting circuit is being brought under sensor control. In a retrofit the usual approach is to mount the pack at the fixture or junction box on the switched leg and run low-voltage control wiring back to the sensor.
