PWM-120 is one 120W waterproof constant-voltage output LED power supply series. Differentiating from general DC output power supplies, PWM-120 transmits PWM style output, adapting to directly driving all kinds of LED strips that the color temperature can be maintained and the brightness homogeneity can be assured. Adopting a universal input range between 90VAC and 305VAC and incorporating the built-in PFC function, this series is also designed with a 2 in 1 dimming function (0~10Vdc or PWM signal) that simplifies the brightness adjustment for system designers so as to achieve light reduction and energy conservation. Providing a high efficiency up to 91% and a low no load power consumption below 0.5W, PWM-120 can satisfy the energy saving demand for the new generation LED lighting. The class ?? design (without FG pin) and the double insulation weather-resistant cable (SJTW) on the input side make it convenient for users to flexibly install on various types of lighting systems. The enclosure design is a 94V-0 flame retardant plastic case. The interior is fully potted with silicone that enhances the heat dissipation and allows PWM-120 to meet the anti-vibration demand up to 5G; it also thus conforms to IP67 level, enabling PWM-120 to be used in a highly dusty and highly humid harsh environment . The entire series can operate under the temperature between -40~+70?? and comply with the relevant global lighting safety certification.
