The present disclosure relates to a system that utilizes Power over Ethernet (PoE) to supply low voltage direct current (DC) power to a PoE enabled track lighting system. The system facilitates communications with individual track heads located in a PoE enabled low voltage track channel so that the operational characteristics of the individual track heads can be controlled (e.g., dim, brighten, change color), so that feedback on functional status of individual track heads can be obtained, and so that total system current can be regulated. The PoE track lighting system includes a PoE track interface (PTI) device that receives current and communication signals. The PTI device receives the digital communication signals, converts them to a second digital commination signal in a format more suitable for transmission along the communication conductors in the track channel, and transmits the second digital communication signal to the communication conductors of the track channel.

Power over Ethernet-based track lighting system

An electrical power pack may include a first power switch and a cycle control to cycle between the first power switch and a second power switch. An electrical power pack may include a first power switch and a delay element to delay an operation of the first power switch. A power pack system may include a first power switch to operate in response to a constant-on control and a second power switch to operate in response to an automatic control. A power pack system may include a first power switch to operate in response to a manual-on control, and a second power switch to operate in response to an automatic-on control.

Bi-level switching with power packs

The present invention discloses an apparatus and method for converting a low voltage occupancy sensor to a powered stand-alone unit. The invention uses a low voltage occupancy sensor mounted in an upper portion of a housing with its associated low voltage wiring terminating in a terminal block. An attachable corresponding lower housing is provided with a power pack adapted to connect with the low voltage terminal block wherein once combined the upper and lower housing portions combine to form an integral powered stand-alone sensor unit.

Occupancy sensor powerbase

A sensor mounting mechanism that includes a base member adapted to be mounted to a structure and a base neck having a first end and a second end where the first end is adapted to be coupled to a sensor with a ball-socket coupling and the second end is coupled to the base member with a rotating coupling. The mounting mechanism provides fine and coarse adjustment means for adjusting the scanning area of the sensor such as an PIR occupancy sensor without the use of a tool. The sensor includes a detachable lens holder for easy replacement of the lens.
