PP20 2P

Power Pack with 2 20 Amp Relays, 120/277 VAC

Power Packs are the heart of the Low Voltage Sensor System. The PP20 transforms 120, 240 or 277 Volts to Class II 15 VDC to power the remote sensors. Utilizing our Patented Relay Circuit Protection the PP20 also switches the lighting load On and Off. This method has been tested to over 400,000 cycles at rated load! Although Plenum Rated, the elongated mounting nipple allows for the PP20 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 PP20. Multi-circuit control can be handled by multiple PP20's, or via 2-Pole Power Packs (PP20 2P) and Slave Packs (SP20). PP20's can be wired continuously hot (line side), or on the switch leg (load side) without nuisance delays upon turn on.
