Meanwell PWM-120 Series Switching Power Supply Description

The Meanwell PWM-120 Series is a 120W AC/DC LED driver designed for constant voltage operation with PWM-style output. This ensures uniform brightness and consistent color temperature across various LED strips. The series operates within an input voltage range of 90-305VAC, and is available in multiple output voltage options from 12V to 48V. Featuring high efficiency up to 90.5%, the fanless design allows the unit to operate in temperatures ranging from -40°C to +90°C. It is rated with an IP67 ingress protection level, making it suitable for dry, damp, or wet environments. The PWM-120 also includes a dimming function that adjusts the output duty cycle, offering flexibility for a variety of LED strip applications.
