DA1 DALI Constant Voltage LED Dimmer | 1-Channel 12–36V PWM

Overview

The DA1 Constant Voltage DALI LED Dimmer is a 1-channel DALI-2 compatible PWM dimmer designed for 12–36V LED strips and constant-voltage LED fixtures. It supports DALI DT6 dimming, delivering smooth 0–100% brightness control with 8A maximum output current. With high-precision PWM output, overload/short-circuit protection, and a compact installation size, the DA1 is ideal for residential, commercial, and architectural LED lighting projects requiring reliable DALI control.

Key Features

• Single DALI address, one output channel (1× CV LED dimmer)
• Supports DALI DT6 (linear or logarithmic dimming curve)
• 12–36V DC input voltage for compatibility with most LED strips
• High output current: up to 8A (max 192–288W depending on voltage)
• Smooth 0–100% dimming via constant-voltage PWM output
• Dimming frequency up to 1.5 kHz for flicker-free performance
• Optional Push-Dim (momentary switch) control for on-site adjustment
• Over-load, over-temperature, and short-circuit protection
• Compact and easy to install in tight spaces
• Compatible with DALI-2 masters and standard DALI bus systems

Technical Notes

• The DA1 is a constant-voltage PWM dimmer — it must be used with 12V, 24V, or 36V LED strips or CV LED fixtures.
• Does not generate DALI bus power; requires an external DALI PSU on the DALI line.
• Supports both logarithmic and linear dimming curves depending on DALI master configuration.
• Output current up to 8A; ensure total LED strip load does not exceed wattage limits at the selected voltage.
• PWM output guarantees flicker-free dimming suitable for video/photography lighting.
• Push-Dim input allows local wall-switch control without a DALI master.
• Temperature protection reduces output or shuts down the driver if overheating occurs.
• Ensure adequate ventilation around the device when using high loads.

Wiring & Installation Notes

• Connect LED strips to the output terminals observing correct polarity (V+ / V−).
• Power the unit with a regulated DC power supply (12–36V DC).
• Connect DALI bus lines to DA+/DA− following correct polarity and bus standards.
• If using Push-Dim: connect a momentary, non-latching switch to the Push input.
• Ensure the total LED strip wattage does not exceed the rated output power.
• Mount in a dry indoor location; IP20 rated.
• Operating temperature: –20°C to +50°C; ensure proper ventilation.
• Follow local electrical standards and LED driver compatibility guidelines.

Applications

• LED strip lighting (12V / 24V / 36V constant voltage)
• Residential cove lighting and linear lighting
• Commercial and retail display lighting
• Office ambient lighting and architectural effect lighting
• DALI-based smart lighting systems
• Hotels, restaurants, and hospitality installations
