SENSORWORX power pack controllers transform incoming line voltage power to Class 2 low voltage as needed by sensors or other control devices. Additionally, they switch on/off power to the connected lighting load as directed by the sensors and controls. SENSORWORX power packs utilize a powerful microprocessor to optimize its switching timing in order to ensure long relay life even when controlling high-inrush LEDs and ballast loads. As with all SENSORWORX products, these power packs are easy to install and incorporate features which reduce contractor labor time. An elongated chase nipple with snaps for quick installation and an optional snap-on low voltage wire chamber make for a hassle free contractor experience. All SENSORWORX products are proudly made in the USA.

An input signal indicating occupancy from one or more connected sensors will signal the pack’s
integrated relay to close. Once closed, line voltage will flow through the relay and turn on the connected lighting load. When the input signal indicates the occupied period has ended, the relay
will open and lighting will switch off. This pack is also available with an auxiliary switch input
to enable manual on, hold on, and hold off configurations. Partial off (e.g. auto off to 50%) and
partial on (e.g., auto on to 50%) operation can also be achieved using the optional 0-10V stepped dimming output.
