Skydance DA4-M 4 Channel Constant Voltage DALI LED Dimmer Owner’s Manual

Skydance DA4-M 4 Channel Constant Voltage DALI LED Dimmer

Product Information

The 4-Channel Constant Voltage DALI LED Dimmer, Model No. DA4-M is a DALI (Digital Addressable Lighting Interface) compatible dimmer designed for LED lighting applications. It supports 1 DALI address and offers 4 channels of output. The dimmer is compatible with various dimming modes, including DT6 dimming, DT8-TC color temperature control, DT8-RGB color control, and DT8-RGBW color control. It follows the DALI standard protocol IEC 62386-102, IEC 62386-207, and IEC 62386-209, ensuring interoperability with DALI products from different manufacturers. The dimmer features automatic DALI address assignment, PWM digital dimming with a standard DALI logarithmic dimming curve, and built-in over-load and short circuit protection.

Product Usage Instructions

Mechanical Structures and Installations:

The DA4-M dimmer has an LED indicator and is designed for installation on an installation rack.
It features two groups of DALI signal inputs, and the DALI bus does not require distinguishing plus-minus polarity.
It also has a DIP switch for selecting the light type.

Wiring Diagram:

The wiring diagram varies depending on the type of LED strip being used.

DA4-M for single color:

• Connect the DALI signal inputs (DA1 and DA2) to the DALI Master.
• Connect the power input (12-48VDC) to the AC power source.
• Connect each output channel to a single color LED strip.

DA4-M for dual color:

• Connect the DALI signal inputs (DA1 and DA2) to the DALI Master.
• Connect the power input (12-48VDC) to the AC power source.
• Connect the first two output channels to a dual-color LED strip (CW and WW).

DA4-M for RGB:

• Connect the DALI signal inputs (DA1 and DA2) to the DALI Master.
• Connect the power input (12-48VDC) to the AC power source.
• Connect the first three output channels to an RGB LED strip (R, G, and B).

DA4-M for RGBW:

• Connect the DALI signal inputs (DA1 and DA2) to the DALI Master.
• Connect the power input (12-48VDC) to the AC power source.
• Connect the first four output channels to an RGBW LED strip (R, G, B, and W).

DALI Control:

The DA4-M dimmer supports DALI control. The DALI address is automatically assigned by the DALI Master controller. Please refer to the user manuals of compatible DALI Masters for specific operations.

Safety & Warnings:

Refer to the User Manual Ver 2.0.1 for safety instructions and warnings related to the DA4-M dimmer.
