Product information

Description

The MEAN WELL PWM-40-12 is a universal power adapter with a rated output of 40.08 W and a wide input range of 90–305 V AC. Designed for powering LED strip installations, the compact black unit (53 × 150 × 35 mm) offers high efficiency and a long MTBF, and includes a 1.8 m flex and plug for straightforward connection.

Advantages

This adapter provides even PWM dimming down to 0% output and supports dimming control via resistance, 0–10 V control, or an external PWM signal. It achieves up to 90% efficiency, ensuring lower energy loss during operation, and its universal input makes it compatible with a wide range of mains voltages. The supplied 1.8 m cable and plug simplify installation in typical lighting setups.

Suitable for

  • LED strip lighting in residential and commercial spaces
  • Applications requiring PWM dimming to zero percent
  • Installations using 0–10 V or resistance-based dimming controls
  • Retrofit and new-build lighting projects with 90–305 V mains

Key specifications

  • Model: MEAN WELL PWM-40-12
  • Output power: 40.08 W
  • Input voltage: 90–305 V AC
  • Dimming methods: Resistance, 0–10 V, PWM signal
  • Efficiency: Up to 90%
  • Dimensions (W×D×H): 53 × 150 × 35 mm
  • Cable: 1.8 m flex and plug
  • Color: Black
  • MTBF: 995,500 hours

How to use

Mount the adapter in a dry, ventilated location and connect the mains input (90–305 V AC) according to local electrical codes. Connect the LED strip load to the adapter output, and use the chosen dimming method—resistance, 0–10 V control, or an external PWM signal—to adjust brightness. Ensure all connections are secure before powering on. Follow the manufacturer's wiring diagram and safety instructions when integrating into lighting circuits.

Usage recommendations

For reliable performance, install the adapter with adequate airflow and avoid enclosing it in tight, unventilated spaces. Match the LED load to the rated output and choose a compatible dimming control (resistor, 0–10 V controller, or PWM source) to achieve smooth dimming down to zero percent.
