Identification & Application WESTGATE LED UCM-40L-12DC 40W Magnetic Dimmable LED Driver 5" x 2-1/8" x 2" 12VDC The Westgate UCM-40L-12DC is a 40 watt magnetic dimmable LED driver designed to convert 120V AC input power into a regulated 12V DC output for compatible low-voltage LED lighting systems. It is intended for hardwired installations where reliable Class 2 power and smooth magnetic dimming are required. The compact black powder-coated steel enclosure measures 5 inches long by 2-1/8 inches wide by 2 inches deep, making it ideal for low-profile installations. The driver is encapsulated with polyester resin to promote whisper-quiet operation while protecting internal components. This magnetic LED driver is compatible with most low-voltage magnetic dimmers when minimum dimmer load requirements are met. Built-in primary and secondary auto-reset breakers help provide dependable circuit protection during normal operation. Visible specifications confirm a 40W maximum output, 120V AC input, 12V DC output, UL 1310 Class 2 compliance, 18 AWG input leads, 14 AWG output leads, and a compact 5" × 2-1/8" × 2" enclosure.
