LEDWCD040S070PS is a 40W constant current LED driver designed for high-efficiency LED lighting systems with integrated dimming control 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 a wide AC input voltage range of 90V to 305V at 47Hz to 63Hz frequency, delivering a constant output current of 665-735 mA with a maximum output voltage of 54 Vdc and output voltage range of 18V to 54V. The unit is fully waterproof rated IP66, complies with UL8750 and EN61347 safety standards, and includes 0-10V dimming control via secondary-side circuitry. This driver is ideal for outdoor LED lighting installations, architectural lighting, and industrial LED applications where reliability, efficiency, and dimming functionality are essential.
