ESS Tri-Mode Dimming™ Constant Current LED Drivers

ERP Power ESS Tri-Mode Dimming™ (up 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 ESS series offers a lifespan of 109,000 hours at +70°C case hot spot temperature (+57°C ambient temperature) for ESS030W-0620-42 (26W). These LED drivers from ERP Power are compliant with FCC CFR Title 47 Part 15 Class B (120V_AC)/Class A (277V_AC) and EN55015 (CISPR 15) at 220/230/240 Vac and ENERGY STAR® luminaire specifications and DLC (DesignLight Consortium®) technical requirements.
