PP20 347

Power Pack, 347 VAC

The 347 VAC Power Packs are the heart of the Low Voltage Sensor System. The PP20 347 transforms 120 or 347 Volts to class II 15 VDC to power remote sensors. Utilizing patented relay contact protection the PP20 347 also switches the lighting load On and Off. This feature has been tested to over 400,000 cycles at rated load! Although plenum rated, the elongated mounting nipple allows for the PP20 347 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 347. Multi-circuit control can be handled by multiple PP20 347's or in combination with Secondary Packs (SP20 347). PP20 347's can be wired continuously hot (line side), or on the switch leg (load side) without nuisance delays upon turn On.
