Mini Power Packs from Sensor Switch are to be used with Low Voltage Sensors and they transform 120, 240 or 277 Volts to Class II 15 VDC to power the remote sensors. With an elongated mounting nipple, the Mini Power Pack can 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 Mini Power Pack and they can be wired continuously hot (line side), or on the switch leg (load side) without nuisance delays upon turn On.
