FAQ

What does the Mean Well DAP-04 do?

The Mean Well DAP-04 is a DALI-to-PWM signal converter. It takes a DALI or push-dim input and provides 4 PWM dimming output channels for dimmable MEAN WELL AC/DC LED power supplies. This makes it useful when a project uses DALI control but the power supply expects a PWM dimming signal.

What types of products is the DAP-04 intended to work with?

This model is specifically described for use with dimmable MEAN WELL AC/DC LED power supplies, connected to their DIM+ and DIM- lines. Each of its 4 output channels can control up to 20 MEAN WELL LED power supplies. It is positioned as a signal-conversion accessory rather than a standalone LED power supply.

Is the DAP-04 a good fit for commercial or B2B lighting control projects?

Yes, the DAP-04 is well suited to B2B lighting projects where DALI-based control needs to interface with compatible MEAN WELL LED power supplies. Its role as a signal converter makes it relevant for commercial control schemes that need protocol translation. Buyers evaluating system compatibility should confirm the target power supply is a dimmable MEAN WELL AC/DC LED power supply.

What are the operating temperature limits for the Mean Well DAP-04?

The specified working temperature range for the DAP-04 is -30 degrees C to +60 degrees C, at 20 to 90% RH non-condensing. Storage is rated from -40 degrees C to +80 degrees C. Buyers should compare these limits against the actual ambient conditions of their enclosure.

How compact is the Mean Well DAP-04?

The DAP-04 measures 165 x 46 x 23 mm (L x W x H) and its listed weight is 0.16 kg. That relatively light weight can be useful when evaluating control accessories for panel space or overall system integration. It is best considered as a small signal-conversion component rather than a heavy power device.
