ESM Tri-Mode Dimming™ Constant Current LED Drivers

ERP Power ESM Tri-Mode Dimming™ Constant Current LED Drivers with Fast Startup Time are compatible with TRIAC (forward-phase or leading-edge) / ELV (reverse-phase or trailing-edge) and 0 to 10V dimmers. The ESM series offers linear 0 to 10V dimming transfer functions with 10V=100%, 1V=10%, and 0.1V=1%. These LED drivers from ERP Power are rated for a lifespan of 85,000 hours at +70°C case hot spot temperature (+39°C ambient temperature) for ESM050W-1200-42 (50W).
