Meanwell Driver LCM-40 42W 350-1050mA Constant Current

The Mean Well LCM-40 is a constant current LED driver rated at 42W, engineered to deliver precise and reliable power to professional LED lighting systems. The on-board dip-switch allows output current selection between 350mA and 1050mA, accommodating a wide range of load configurations.

This driver stands out for its versatility and worldwide voltage compatibility, making it the ideal choice for professional residential and commercial installations requiring accurate and flexible LED lighting control.

Key technical features

The driver operates with an input voltage of 220-240V AC and delivers an output voltage variable between 2 and 100V DC, automatically adjusting to the connected load. Its 91% efficiency minimises energy loss and heat generation, removing the need for a cooling fan. The 3-in-1 dimming function supports regulation via 0-10V DC signal, 10V PWM, or resistance connected between the DIM+ and DIM- terminals. Multiple units can be synchronised using the Sync terminal. The compact 123 x 81 x 23 mm footprint and grey ABS housing simplify installation in confined spaces.

Safety and protection

The Mean Well LCM-40 carries Insulation Class II certification and an IP20 protection rating, suitable for dry indoor installations.

Applications

Perfectly suited for LED strips, spotlights, panels and architectural lighting systems requiring constant current control, with full compatibility across EU, USA, UK, Australia and Japan voltage standards.
