DALI-2 Dimmable Emergency LED Driver 10W With Li-ion Battery Maintained Non-Maintained
The DF-DALI-10W is a high-performance DALI-2 compliant LED emergency power kit designed in accordance with IEC62386-102/202 standards for modern commercial and industrial emergency lighting systems. Supporting a wide AC 90–280V input and an output voltage range of DC 12–60V, it provides up to 10W emergency power output and 1 to 3 hours of continuous backup illumination during power outages. Equipped with intelligent DALI bus centralized monitoring, automated periodic self-testing (function and duration tests), and comprehensive fault diagnostic indicators, this kit—paired with a high-quality 7.4V lithium battery—delivers a safe, reliable, and code-compliant emergency lighting solution for office buildings, shopping malls, and public facilities.
Description
Smart & Reliable Emergency Solution for Modern LED Lighting Systems
The DF-DALI-10W LED Emergency Power Kit is an advanced emergency control unit engineered to seamlessly integrate into DALI lighting control systems, offering intelligent centralized management and automated compliance testing for building safety.
Key Features & Selling Points:
Full DALI-2 Standard Compliance: Strictly meets IEC62386-102/102/202 protocol standards. Supports networking up to 64 devices on a single DALI bus for centralized monitoring, address assignment, group management, scene setting, and remote emergency status tracking.
Automated Periodic Self-Test System: Features customizable, automated Function Tests (verifying instant emergency switching) and Duration Tests (evaluating battery capacity and runtime). Saves significant labor and maintenance costs by eliminating manual inspection routines.
Real-Time Fault Diagnostics & Visual Indicators: Equipped with dual-color LED status indicators and DALI software status feedback to immediately report issues such as LED load open/short circuit, battery disconnection/failure, or low battery capacity.
Wide Voltage & Flexible Working Modes: Compatible with AC 90–280V mains input and DC 12–60V LED light sources, supporting external standard drivers up to 40W. Features selectable Persistent (Maintained) and Non-Persistent (Non-Maintained) modes, along with Inhibit and Rest (Sleep) modes for convenient maintenance and testing.
High Safety & Rapid Switching: Triggers emergency operation in less than 0.5 seconds upon main power failure. Built with high-voltage protection on DALI terminals (withstanding over 260V) and full CE and RoHS compliance for maximum operational safety.
