DALI to PWM converter DAP-04-S01

DALI to PWM Converter – Precise LED Lighting Control

The DALI to PWM converter, model DAP-04-S01 from MEAN WELL, is a device that enables smooth control of LED lighting via the DALI interface. It allows the use of advanced control functions, such as dimming, in installations using PWM power supplies. This is particularly useful in smart lighting systems where precise control over each light point is required. The device is dedicated to working with MEAN WELL power supplies equipped with a 3-in-1 dimming function, but can also be used with other compatible power supplies.

Functionality and application

DAP-04-S01 converts the DALI control signal into a PWM signal that is understandable for LED power supplies. It has one or four addressable output channels (depending on the model), allowing independent control of individual lighting groups. The 'push dimming' function allows you to adjust the light intensity by briefly short-circuiting the phase wire to the converter input – a simple solution ideal for use in residential and office spaces. Additionally, the converter allows you to set the minimum dimming level using the DALI protocol, which ensures user comfort and optimizes energy consumption.

Construction and parameters

The converter is characterized by a wide range of input voltages (90-305 VAC), which ensures compatibility with various electrical networks. The standby power consumption is very low – below 0.5 W – which translates into energy savings. The housing made of plastic provides Class II insulation (without grounding) and protects the device from external factors. Compact dimensions (165 mm x 46 mm x 23 mm) make it easy to mount in a limited space. The device operates in a wide range of ambient temperatures (-30°C to +60°C), allowing it to be used in various environmental conditions. A built-in ON/OFF relay enables remote switching of the connected LED power supply.

The DAP-04-S01 converter is a reliable and efficient solution for professionals and end customers looking for an advanced LED lighting control system.
