Ltech SE-20-250-1000-W2D2 Quick Start Manual

Intelligent Tunable White LED Driver
Dimming interface: DALI-2 DT6/DT8.
T-PWM™dimming technology allows continuous and flicker-free images
under high-speed photography.
With soft-on and fade-in dimming function, enhancing your visual comfort.
Dimming from 0~100%, down to 0.1%.
Adopt constant power design that can adjust different color temperature while
brightness remains the same.
Comply with the EU's ErP Directive, standby power consumption < 0.5W.
DALI bus standard IEC62386-101, 102, 209.
Innovative thermal management technology intelligently protects the life of
the LED driver.
Overheat, over voltage , overload, short circuit protection and automatic recovery.
Ⅰ/Ⅱ/Ⅲ
Suitable for Class indoor light fixtures.
,
Up to 50 000-hour life time.
5 years warranty (Rubycon capacitor).

Protection
Over temp. protection: Intelligently adjusting or turning off the output current
if the PCB temperature ≥110°C, auto recovers.
Shut down the output when current load≥102%, auto recovers.
Over load protection:
Short circuit protection: Shut down automatically if short circuit occurs, auto recovers.
Over voltage protection:
Output current declined when over non-load voltage,
auto recovers.
