DA4-D DALI LED Dimmer | 4CH 5A DT6/DT8 DIN Rail CV Controller

Overview

The DA4-D is a professional 4-channel constant voltage LED dimmer designed for DIN-rail installations in DALI-based lighting systems. Supporting both DT6 and DT8 modes, it provides flexible, high-performance control for single-color, tunable white, RGBW and multi-channel LED strip systems. With 5A output per channel and a 12–48V DC input range, the DA4-D delivers smooth flicker-free dimming and color mixing for architectural, commercial and centralized lighting installations.

Key Features

• 4-channel constant voltage output (4×5A)
• Supports DALI DT6 (individual channel dimming)
• Supports DALI DT8 (RGBW / color mixing control)
• 12–48V DC wide input range
• DIN-rail housing for cabinet and control panel integration
• Smooth flicker-free PWM dimming (0–100%)
• High output capacity for large LED installations
• Memory function for restoring brightness and color state
• Ideal for smart building lighting and automation systems

Technical Notes

• DT6 mode: 4 independent dimming channels.
• DT8 mode: RGBW control using a single DALI address.
• DIN rail design simplifies integration into electrical cabinets.
• Suitable for commercial buildings, hotels and architectural lighting.
• Constant voltage PWM output ensures stable and smooth operation.

Applications

• Centralized DALI lighting systems
• RGBW, tunable white and multi-channel LED strip control
• Building automation and DALI-2 networks
• Control rooms, electrical cabinets and smart lighting panels
• Architectural and façade lighting
• Premium indoor commercial environments
