MEAN WELL DAP-04 DALI to PWM Signal Converter, 4 Channel

The MEAN WELL DAP-04 DALI to PWM Signal Converter is a sophisticated interface unit designed to bridge the gap between DALI lighting control systems and PWM-dimmable LED drivers. It seamlessly converts a standard DALI control signal into a PWM output, specifically engineered to work with MEAN WELL's own range of AC/DC LED power supplies featuring a 3-in-1 dimming function (compatible with 1-10V, PWM, and Resistance dimming methods). This enables advanced, addressable lighting control for installations requiring reliable and flexible dimming solutions.

Featuring four independently addressable DALI output channels, this converter allows for grouped or individual control of multiple lighting circuits from a single DALI line. It offers extensive configurability, with user-selectable options for PWM signal polarity (active high or active low via a jumper) and dimming curve (linear or logarithmic in compliance with IEC62386-207), providing perfect dimming performance for various LED types and applications. The device includes a built-in push dim function for manual control and a relay for direct ON/OFF switching of the connected LED power supply, adding to its operational versatility.

Housed in a fully isolated plastic case as a Class II power unit (requiring no functional earth connection), it ensures safe installation. With universal AC input covering a full range up to 305V AC and very low power consumption (less than 0.5W), it is both energy-efficient and adaptable to various mains voltages. Its compact dimensions make it easy to integrate into control cabinets, luminaires, or other confined spaces.
