DALI linear constant current LED drivers are advanced, addressable lighting controllers designed for professional, commercial, and, smart home applications. They provide flicker-free, 0–100% (or deep 0.01%) dimming using DALI-2 (DT6/DT8) protocols, allowing for individual control or grouping of lights, often featuring NFC programmability for precise current adjustment (e.g., 100-1050mA) and long, slim, IP20-rated designs for linear fixtures.

Key Features & Advantages

DALI-2 Compatibility: Certified for reliability within modern Digital Addressable Lighting Interface (DALI) systems, allowing for bidirectional communication for control and monitoring.

Constant Current (CC) Output: Ensures consistent brightness for LEDs by supplying a steady current, typically adjustable via DIP switches or NFC, ranging from 250mA to 1000mA+.

NFC Programmability: Many modern drivers, such as those from Sunricher and KGP, allow for setting output current, DALI addresses, dimming curves (linear/logarithmic), and fade rates via an NFC smartphone app.

Linear Form Factor: Designed to fit into slim, linear luminaires or profile lighting.

High-Quality Dimming: Capable of deep, smooth, flicker-free dimming down to 0.01%, often supporting PWM (Pulse Width Modulation).

Safety & Reliability: Typically includes built-in protection against short circuits, overloads, and overheating, often with a 5-year warranty.

Common Applications

Commercial Lighting: Office, retail, and architectural spaces requiring flexible,, addressable lighting control.

Linear Fixtures: Perfect for LED strip, channel, or Batten light fixtures.

Tunable White (DT8): Some models, such as from LTECH, support DALI DT8 to control CCT (1000K-10000K).
