DA1-S Constant Voltage DALI Touch Dimmer | 1-Channel LED Panel

Overview

The DA1-S is a single-channel constant voltage LED dimming wall panel designed for 12–36V LED strips and constant-voltage LED luminaires. It provides smooth PWM dimming from 0–100%, supporting both DALI DT6 control and Push-Dim functionality. The high-quality glass touch interface offers direct brightness control, while its DALI compatibility allows seamless integration into smart lighting systems. With up to 8A output current and robust protections, the DA1-S is suitable for residential, commercial, and architectural LED lighting applications.

Key Features

• Single-channel constant voltage LED dimmer (PWM output)
• Supports DALI DT6 dimming and Push-Dim (momentary switch)
• 12–36V DC input for LED strips and CV LED fixtures
• High output current up to 8A for powerful LED installations
• Glass touch panel with smooth brightness adjustment
• 0–100% dimming with flicker-free PWM
• Selectable dimming curves (linear/logarithmic via DALI master)
• Over-temperature, over-load, and short-circuit protection
• Designed for standard 86 mm wall box installations
• Compact, clean, and modern touch interface for interior spaces

Technical Notes

• This is a constant voltage PWM dimmer—compatible with 12V, 24V, or 36V LED strips only.
• The DA1-S does not supply DALI bus power; an external DALI PSU is required for DALI mode.
• Supports DT6 dimming with smooth 0–100% brightness control.
• Maximum output: 8A; ensure the total LED load does not exceed wattage limits.
• PWM output ensures flicker-free dimming suitable for cameras and studio lighting.
• Push-Dim mode allows full local control without a DALI controller.
• Temperature protection will reduce output or shut down the dimmer if overheated.
• Best performance is achieved with high-quality constant-voltage LED drivers.

Wiring & Installation Notes

• Connect the LED strip to the CV output terminals (V+ / V–).
• Supply the unit with a regulated 12–36V DC power source.
• Connect DALI bus wiring to DA+ / DA– if using DALI control.
• For Push-Dim, connect a momentary (non-latching) switch to the Push input.
• Ensure the LED load does not exceed maximum rated wattage and 8A output.
• Install into a standard 86 × 86 mm wall box.
• Indoor use only; IP20 protection rating.
• Operating temperature: –20°C to +50°C — allow proper heat dissipation.

Applications

• LED strip dimming (12V / 24V / 36V constant voltage)
• Residential mood and ambient lighting
• Commercial and retail lighting control
• Hotel rooms, hospitality environments, and restaurants
• Architectural cove, linear, and indirect lighting
• DALI-controlled smart lighting installations
