D4I UL Listed CC 100W-720W Outdoor DALI-2 D4I NFC Dimmable LED Power Supply

Product Introduction

The SDU Series Constant-Power Dimmable LED Driver is designed for high-power outdoor and professional LED lighting applications, supporting a 120–277VAC input and a wide output voltage range. Based on an LCC topology and advanced control architecture, the series provides high power factor, low THD, and standby power consumption of less than 0.5W. Its constant-power design allows programmable output current adjustment, while NFC programmability enables convenient field configuration and current setting.

The SDU Series integrates multiple functions for precise lighting control and long-term system reliability. It supports isolated DALI-2 dimming from 1–100% with 1% dimming depth, as well as optional output lumen compensation and an end-of-life indicator. The driver also supports optional three-stage timer modes for applications requiring scheduled lighting control. Built-in short-circuit, overload, and over-voltage protection, together with 6kV differential-mode and 10kV common-mode surge protection, helps protect the LED lighting system under demanding outdoor operating conditions.

With IP67 protection and UL suitability for dry, damp, and wet locations, the SDU Series is suitable for street lights, stadium lights, square and area lighting, plant lighting, and other high-power outdoor applications. Its professionally designed housing and efficient thermal management support reliable heat dissipation and long service life. The integrated DALI auxiliary power interface provides 18V/50mA bus power, capable of supporting approximately 25 compatible DALI power supplies, while the 24V/125mA (3W) auxiliary power output supports additional control-system requirements. The series is backed by a 5-year warranty.
