ESS040W-0800-42 Description

Short technical summary and product information.

The ERP Power ESS040W-0800-42 is a constant current LED driver designed for indoor and outdoor lighting applications. It provides 800mA output current over a voltage range of 28-42V, delivering up to 34W of power. The driver accepts universal input voltage from 120 to 277 VAC and features Tri-Mode Dimming™ compatibility with TRIAC (forward-phase), ELV (reverse-phase), and 0-10V dimmers. It offers high efficiency up to 87% typical, with a power factor >0.9 and THD <20%. The driver is housed in a compact plastic case measuring 83.8 x 39.9 x 25.1 mm with wire leads termination. It is IP64 rated for protection against dust and water splashes, and features silicone-based potting for thermal management. Protections include output open load, over-current, short-circuit (hiccup), and over-temperature with auto recovery. The driver complies with FCC Part 15 Class B (120 Vac) and Class A (277 Vac), EN55015, and has worldwide safety approvals including cUL, UL, cRUcs, FC, CE, CB. It is RoHS3 compliant and REACH unaffected.
