The ESP040W-0900-42 is a high-efficiency constant current LED driver designed for architectural, commercial, and residential lighting. It features a compact, potted metal case for high thermal performance and supports universal input voltages from 120 to 277 VAC. The driver provides triple-mode dimming, including TRIAC (leading-edge) and ELV (trailing-edge) at 120 VAC, and 0-10V dimming across the full input range. It is protected against over-current, over-temperature, short-circuit, and open-load conditions.
