Containing both a 24VDC supply and a 20A line voltage relay for most models, the Leviton® compact power pack provides low voltage power and line voltage control for Leviton® occupancy Sensors. Versions include auto-on and manual-on inputs for occupancy sensors, Hold-ON and hold-off capabilities and a local input for momentary or maintained dry contact switches. The OSP power pack series is also used to supply power to the OSA Add-A-Relay model. The power pack conveniently mounts in a knockout hole of a standard junction box. The unit can be placed inside or outside the junction box with a simple twist-on nut. The internal relay can control up to 20 amps at either 120, 230 or 277 VAC ballast load, 15 Amp for 347 VAC ballast load.
