The ESP040W-0940-43 is a constant current LED driver from ERP Power, LLC, part of the ESP series. It delivers 40W output at 940mA with an output voltage range of 35 to 43 VDC. The driver accepts universal input voltage from 120 to 277 VAC and achieves up to 87% typical efficiency with a power factor greater than 0.9 and total harmonic distortion below 20%.
This driver supports tri-mode dimming including 0-10V analog, TRIAC (forward-phase), and ELV (reverse-phase) dimming methods, with a dimming range of 1% to 100%. It features a fast startup time of 300 ms typical. Protection features include over-current protection (OCP), over-temperature protection (OTP), and short-circuit protection (SCP) with auto recovery.
The driver is housed in an IP64-rated plastic case with silicone-based potting, making it suitable for damp locations. It measures 87.0 mm x 59.9 mm x 27.2 mm and terminates with wire leads. The operating temperature range is -30°C to 90°C with a maximum case temperature of 90°C. Rated lifetime is 50,000 hours minimum at 70°C case temperature.
The output current is 940 mA, constant current.
