SUNPOWER 18W Constant Current LED Power Supply

The SUNPOWER 18W Constant Current LED Power Supply provides a stable, efficient, and dimmable power source for a variety of LED lighting installations. Operating in constant current mode ensures your LEDs receive a consistent, flicker-free current of 500mA, maximising their lifespan and performance. It accepts a standard UK mains input of 220-240Vac and delivers a maximum output voltage of 18VDC, making it suitable for powering a range of LED modules and strips.

A key feature is its integrated 1-100% Triac dimming function, offering smooth and wide-ranging light level control from full brightness down to a gentle glow, compatible with standard trailing-edge dimmer switches. This driver is packed with protective features for peace of mind, including safeguards against short circuit, overload, and over-temperature conditions.

Designed for ease of installation and reliability, it features captive terminal screws for secure and straightforward wiring connections. A snap lock cable strain relief system ensures cables are held firmly in place, preventing damage from pulling or twisting. As a Class II (double insulated) product, it does not require an earth connection, simplifying setup in a variety of locations. Cooling is managed efficiently through free air convection, ensuring quiet operation and long-term reliability.
