The MP20 power/relay pack works with low voltage occupancy sensors to switch lighting loads on and off. The MP20 also transforms 120, 240, and 277 VAC single phase power to Class 2 15 VDC to power remote sensors. Although plenum rated, the elongated mounting nipple allows for these packs to be mounted either directly through a 1/2 inch knockout in a junction box, or to be located inside an adjacent box for specific local code requirements. Up to 14 sensors may be connected to one MP20. Multi-circuit control can be handled by multiple MP20. MP20s can be wired continuously hot (line side), or on the switch leg (load side) without nuisance delays upon turn on.FEATURES:• Powers Low Voltage Sensors (MP20)• Switches Line Voltage Loads• Plenum Rated
