The ESS040W-0900-42 is a constant current LED driver from ERP Power, LLC, part of the ESS series. It provides an AC-DC converter topology with a single output rated at 38W, delivering 900mA over a 28-42V range. The driver supports multiple dimming methods including TRIAC (forward-phase), ELV (reverse-phase), and 0-10V analog dimming, with a dimming range of 1-100% of output current.
Electrical specifications include an input voltage range of 120-277 VAC (TRIAC/ELV limited to 120 Vac), typical efficiency of 87%, power factor above 0.9, and total harmonic distortion below 20%. Protection features include over-current, over-temperature, and short-circuit protection with auto recovery. The driver has a startup time of 400 ms.
The driver is housed in an ESS plastic case measuring 83.8 x 39.9 x 25.1 mm with wire lead terminations. It is rated IP64 and NEMA 410 for environmental protection and has an operating temperature range of -30°C to 90°C with a maximum case hot spot temperature of 90°C. The lifetime is rated at 50,000 hours at 70°C case hot spot.
Compliance certifications include cUL, UL, cRUcs, FC, CE, CB; FCC Part 15 Class B at 120 Vac and Class A at 277 Vac; EN55015; ENERGY STAR; DLC; and CA Title 24. The driver is RoHS3 compliant and REACH unaffected, with MSL Level 1 (unlimited).
