## Summary description

Single-output LED power supply Mean Well PWM-120-12DA2 provides 12 V DC at 10 A output and supports DALI2 dimming control. Designed for driving LED strips, modules or luminaires, it enables smooth dimming via DALI2 systems and offers a compact solution for commercial and residential lighting installations requiring stable 12V power and digital dim control.

## Long description

Mean Well single-output LED power supply PWM-120-12DA2 delivers 12 V DC at 10 A and integrates DALI2 dimming control for digital brightness management. This compact, constant-voltage unit is intended to drive LED strips, LED modules and luminaires that require a stable 12V supply and DALI2-compatible dimming. The power supply includes standard protections and a form factor suitable for both commercial and residential installations where reliable low-voltage power and smooth dimming are needed.
Advantages
The unit provides a stable 12 V output at a rated 10 A, ensuring consistent performance for connected LED loads. Built-in DALI2 dimming control enables precise, digitally controlled brightness adjustment and integration with DALI lighting systems. The compact design simplifies installation in confined spaces, while typical Mean Well safety and protection features—such as short-circuit, overcurrent and overvoltage protection—help maintain reliability in daily operation.
Suitable for
Indoor LED strip lighting in retail, hospitality or residential spaces
LED module and linear luminaire installations that require 12V constant-voltage supply
DALI2-enabled lighting control systems for synchronized dimming
Projects where a compact power supply with digital dimming is required
Key specifications
Output voltage: 12 V DC
Rated output current: 10 A
Output power: 120 W
Dimming interface: DALI2 compatible digital dimming
Type: single-output constant-voltage LED power supply
Protection features: short-circuit, overcurrent, overvoltage protection
Application: designed for LED strips, modules and luminaires
How to use
Mount the power supply in a well-ventilated location and connect the AC input according to local electrical codes. Attach the 12 V DC output to the LED load observing correct polarity and total load not exceeding the rated 10 A. Connect the DALI2 control wiring to the DALI terminals following the DALI system layout and addressing procedure. After wiring, apply power and verify correct LED operation and dimming response through the DALI controller. If multiple drivers are used, ensure DALI addressing and system wiring are configured for the intended group control.
Usage recommendations
Install the unit where ambient temperature and ventilation meet the manufacturer's specified conditions, avoid covering ventilation slots, and ensure the total connected LED wattage stays within the 120 W limit. Use appropriate DALI controllers and wiring practices for reliable dimming performance and consult applicable wiring standards or an electrician for compliant installation.
