LTECH SE-20-250-1000-W2D2 20W 250mA ~ 1000mA CC DALI2 LED Driver -...
The SE-20-250-1000-W2D2 is intended for constant current LED lighting applications that need tunable white control. Its DALI DT8 colour temperature adjustment capability makes it relevant for projects where white tone needs to shift within the lighting design. It is a 20W driver, so it suits lower-power fixtures that match its output range.
Input 100~240VAC. Operating temperature 20~+90°C. Backed by a 5 year warranty.

Frequently Asked Questions
What type of LED applications is the LTECH SE-20-250-1000-W2D2 designed for?
This model is intended for constant current LED lighting applications that need tunable white control. Its DALI DT8 colour temperature adjustment capability makes it relevant for projects where white tone needs to shift within the lighting design. It is a 20W driver, so it suits lower-power fixtures that match its output range.
What are the key output specifications of the SE-20-250-1000-W2D2?
This LED driver is rated at 20W with a maximum output voltage of 59V. It supports an adjustable constant current range from 250mA to 1000mA, with the listed rated current at 250mA. These specifications make it a constant current driver rather than a constant voltage power supply.
Does this LED driver support DALI tunable white control?
Yes. The product description states that it supports DALI DT8 and is a tunable white driver with CT adjustment. It also supports Push DIM and T-PWM digital dimming, giving it broader control compatibility within supported lighting systems.
How smooth is the dimming performance on this model?
The SE-20-250-1000-W2D2 is specified for 0 to 100% dimming and is described as flicker-free. The product description also notes LED start at 0.01% is possible, which is useful for applications that need very low light output. That makes it a strong fit where fine dimming control matters.
What protections and reliability features are included in this driver?
According to the provided description, this model includes short circuit, overload, overheat, overvoltage, and over-temperature protection with automatic recovery. It also uses innovative thermal management technology and intelligent power life protection. The listed warranty period is 5 years.
Is the SE-20-250-1000-W2D2 suitable for demanding temperature conditions?
The provided temperature range is 20 degrees C to 90 degrees C. That indicates the model is specified for elevated operating temperatures at the high end. Buyers should compare their project environment against this stated range when selecting the driver.
