The ERP Power, LLC ERM050W-1800-28 is a 50W constant current LED driver with an AC-DC converter topology. It provides a single output of 1.8A over a voltage range of 21 to 28V, suitable for high-current COB LEDs and various commercial lighting fixtures.
Key electrical specifications include nominal input voltages of 120 and 277 VAC, a typical efficiency of 90%, and analog dimming capability from 10% to 100% of output current. The driver integrates protection features: over-current (OCP), over-temperature (OTP), and short-circuit (SCP) with auto recovery.
The driver is housed in an IP64-rated metal case with silicone-based potting for environmental protection. Mechanical dimensions are 81.5 mm x 56.1 mm x 32.5 mm, with wire lead termination. It operates over a case temperature range of -30°C to 90°C (90°C maximum hot spot).
Typical applications include high bay lights, troffers, outdoor LED lighting, office and industrial LED lighting. The driver complies with FCC Part 15 (Class B at 120 Vac, Class A at 277 Vac) and ENERGY STAR / DLC requirements.
Nominal input voltages are 120 VAC and 277 VAC.
