Powerline Control Systems, Inc. (PCS) is a California-based lighting control and home/building automation technology company headquartered in Northridge, Los Angeles. Founded in 1992, the company developed lighting-control products designed to communicate over existing electrical wiring, reducing the need for additional control wiring. PCS became particularly known for its PulseWorx product family and UPB (Universal Powerline Bus) powerline communication technology, which enabled lighting and automation devices to exchange control signals through a building’s electrical power lines.

Powerline Control Systems has developed and manufactured a range of lighting control products, including dimmers, relays, wall switches, fixture modules, phase couplers, controllers, and related automation components. Its PulseWorx technology was designed for residential and commercial lighting applications, allowing users to control lighting circuits without installing dedicated low-voltage control wiring. Some of its products were designed to meet requirements associated with California building standards, including Title 24 applications.

The company also developed UPStart configuration software, used to configure and program UPB-based automation networks. The system allows devices to be assigned network and unit identifiers, linked into scenes, configured with operating parameters, and tested for communication strength. This technology provided a platform for integrating lighting and automation devices across residential and commercial electrical systems.

Powerline Control Systems has also been associated with patented powerline communication technology, including inventions covering pulse-position-modulated communication systems operating over electrical power lines. U.S. patent records identify Powerline Control Systems, Inc. as an assignee for several of these technologies.

Public business records currently show an active Powerline Control Systems, Inc. registered in California at 19215 Parthenia Street, Suite D, Northridge, while an earlier corporation with the same name is listed as dissolved. The available company/product documentation consistently associates the active business with PCS lighting-control products and the Northridge location.
