Description
Description
The Ltech SE-20-100-700-W2D is a compact 20W constant-current LED driver designed for high-performance tunable white lighting applications. Featuring an adjustable output range of 100-700mA and advanced DALI-2 DT6 / DT8 compatibility, this driver enables smooth dimming and precise color temperature control in architectural, commercial, and residential lighting systems.
With NFC wireless programming, installers can quickly configure output current and operating parameters without powering the driver, reducing installation time and improving job-site efficiency. Its high efficiency, flicker-free performance, and reliable single-channel design make it an ideal solution for linear lighting, downlights, and specialty luminaires requiring dynamic white control.
Engineered for dependable operation and seamless integration into modern lighting control networks, the SE series delivers the flexibility and performance professionals expect from Ltech.
