SensorSwitch 88272 Power Pack with 20 Amp Relay PP20 Power Pack
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!
