The PWM-120 series are 120 W waterproof constant voltage output LED power supplies. Unlike general DC output power supplies, this device transmits PWM style output, adapting to directly drive all kinds of LED strips, ensuring that the color temperature is maintained and brightness homogeneity is assured.

Adopting a universal input range between 90 and 305 VAC and incorporating a built-in PFC function, this series is also designed with a 2-in-1 dimming function (0-10 VDC, PWM signal) or resistance, simplifying brightness adjustment for system designers to achieve light reduction and energy conservation.

Providing high efficiency of up to 90.5% and low no-load power consumption below 0.5W, the PWM-120 can satisfy the energy-saving demands of the new generation of LED lighting. The class II 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 94 V-0 flame retardant plastic case. The interior is fully potted with silicone, enhancing heat dissipation and allowing the PWM-120 to meet anti-vibration demands of up to 5G; it thus conforms to IP67 level, enabling the PWM-120 to be used in highly dusty and highly humid harsh environments. The entire series can operate under temperatures between -40 and +70 °C and complies with relevant global lighting safety certifications.
