Mean Well DAP-04-S01 DALI signal to PWM signal converter - 1 or 4 address selectable

The DAP-04-S01 is a DALI signal to PWM signal converter. It is designed to work with MEAN WELL AC/DC LED power supplies that support 3-in-1 dimming. This model is used when a DALI control signal needs to be interpreted by compatible PWM-capable dimming hardware.

Mean Well specifies this model for use with MEAN WELL AC/DC LED power supplies that have 3-in-1 dimming functionality. The listed 3-in-1 dimming types are 1 to 10V, PWM, and resistance. Compatibility should be evaluated against that dimming capability rather than assuming it fits unrelated drivers or controllers.

This standard model supports selectable 1-address or 4-address operation. That makes it suitable for applications where the control scheme needs either simpler single-address handling or more segmented DALI addressing. The selectable addressing is one of the main differentiators called out for the DAP-04-S01.

It is intended for DALI-based lighting control applications where a DALI signal needs to interface with compatible MEAN WELL LED power supplies. That makes it relevant for commercial and project-based lighting systems already using DALI as the dimming protocol. The product is best matched to setups that specifically require DALI-to-PWM signal conversion.

The specified operating temperature range is -40 degrees C to 80 degrees C. That is a wide range for demanding indoor or protected equipment environments. Buyers with temperature-sensitive projects should compare their actual enclosure and ambient conditions against this stated range.

This model carries a 3-year warranty. Its listed weight is 0.1600 kg, which is 160 grams. Those details can help when comparing controller accessories for project documentation or bill-of-material planning.
