## Long description

The MEAN WELL PWM-90-12 is a 90W power adapter for LED strip lighting that accepts a wide AC input range of 90–305V at 47–63 Hz. Designed for reliable operation with an MTBF of 902,400 hours, the compact black unit measures 63 x 171 x 37.5 mm and includes a 1.8 m flex and plug for straightforward installation. It delivers high efficiency (up to 90.5%) and supports multiple dimming control methods for smooth brightness adjustment.
Advantages
The adapter provides even PWM dimming and can dim down to 0% output, enabling full off control. It supports dimming via resistance, 0–10V signal, or PWM input, offering flexibility for different control systems. High conversion efficiency reduces heat and energy loss, while the long MTBF indicates durable performance for continuous lighting applications.
Suitable for
Indoor LED strip installations requiring dimming control
Commercial and residential accent or task lighting
Retrofit projects where compact power supplies are needed

How to use
Connect the adapter to an AC supply within the specified 90–305 V range and attach the LED strip to the output according to the strip’s polarity and current requirements. Select the preferred dimming control method (resistance, 0–10 V, or PWM) and wire the control signal to the corresponding terminals following the manufacturer's wiring diagram. Ensure the unit is mounted in a location with adequate ventilation and secured to prevent movement.
Usage recommendations
For stable dimming performance, use control signals within the recommended voltage/current ranges and avoid long runs of low-quality signal wiring. Allow clearance around the adapter for heat dissipation and follow local electrical codes during installation.
