Information about the MEAN WELL PWM-40-24

The MEAN WELL PWM‑40‑24 is a 40 W constant‑voltage LED driver with a PWM‑style output at around 1.47 kHz, designed to keep LED strip color temperature and brightness uniform throughout the entire dimming range. This makes it a strong choice for 24 V LED strips, indoor accent lighting, and architectural or decorative LED projects where visual consistency is essential.

With typical efficiency up to 89 %, active power factor correction and a wide 90–305 V AC input range, the driver operates efficiently and can be deployed in worldwide installations. The fully encapsulated IP67 housing, wide −40 to +85 °C case temperature rating and comprehensive protection features (short‑circuit, overload, overvoltage and overtemperature in hiccup/shutdown mode) provide reliable operation in dry, damp and wet locations.

The integrated 3‑in‑1 dimming interface (0–10 V, 10 V PWM signal, resistance) with dim‑to‑off capability offers excellent flexibility for modern control systems and building automation. Combined with extensive international safety and EMC certifications (including type “HL” for use in Class I, Division 2 hazardous locations), the PWM‑40‑24 is ideally suited for professional 24 V LED strip lighting in commercial and industrial environments.
