ESP Tri-Mode Dimming™ Constant Current LED Drivers

ERP Power ESP Tri-Mode Dimming™ (0 to 10V and TRIAC/ELV) 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 ESP series offers linear 0-10V dimming transfer functions (10V=100%, 1V=10%, 0.1V=1%) and a lifespan of up to 134,000 hours at +70°C case hot spot temperature (+37°C ambient temperature) for ESP050W-1050-42 (44 W). These drivers from ERP Power comply with ENERGY STAR® luminaire specification and DLC (DesignLight Consortium®) technical requirements and come in an IP64-rated case with silicone-based potting.
