LEDWCD040S222PS is a 40W constant current LED driver designed for LED lighting applications requiring precise current regulation and dimming capability. The driver features active power factor correction (typical 0.94), high efficiency up to 88%, and comprehensive protection including overvoltage protection (OVP), short circuit protection (SCP), and overload protection (OLP). It operates with an input voltage range of 90V to 305V AC at 47Hz to 63Hz frequency, delivering a rated output current of 2109–2331 mA at 6V–16V output voltage range with a no-load output voltage of 22V. The unit is fully waterproof (IP66 rated), includes dimming control via 0–10V input or potentiometer, and complies with UL8750 and EN61347 safety standards. This driver is ideal for outdoor LED installations, architectural lighting, and applications requiring reliable constant current regulation with environmental protection.
