LMRC-222, Digital Lighting Universal Dimming Room Controller

LMRC-222 Digital Lighting Universal Dimming Room Controller The LMRC-222 is a 2-load forward phase dimming room controller designed for precise lighting control in commercial and institutional settings. It supports a total load capacity of up to 20 amps and is compatible with a broad range of load types including incandescent, magnetic low voltage (MLV), forward phase compatible electronic low voltage (ELV), LED drivers, neon, cold cathode, and dimmable two-wire and three-wire fluorescent ballasts as well as electronic ballasts (E-ballasts). This controller integrates seamlessly into Wattstopper’s Digital Lighting Management (DLM) system, enabling energy-efficient lighting solutions with occupancy sensors, daylight harvesting, and manual or automatic switching. It is suitable for applications such as conference rooms, classrooms, executive offices, restaurants, and galleries.
