Ltech SE-12-100-500-W2D 12W 100-500mA LED Driver - NFC, DALI2, Tunable White

Q: What is the Ltech SE-12-100-500-W2D designed for?

The Ltech SE-12-100-500-W2D is a 12W constant-current LED driver for lighting applications that need dimming control and tunable white support. It is positioned for LED use cases where compact size, precise current adjustment, and DALI2 control are important.

Q: Does this LED driver support DALI dimming?

Yes. This model supports DALI2 dimming control and is identified as a DALI driver in its product data. It also includes T-PWM super deep dimming technology with a stated dimming depth of 0.01% and a soft-on, fade-in dimming function.

Q: What makes this model different from a basic non-dimmable LED driver?

This model adds features aimed at higher-end lighting control, including DALI2 support, NFC functionality, tunable white capability, and adjustable output current in 1mA steps. It also emphasizes visual comfort with flicker-free dimming performance and soft-on fade-in behavior.

Q: What are the key electrical specs of the SE-12-100-500-W2D?

This LED driver is rated at 12W with an output voltage listed at 48V. The product data shows a rated current of 100mA, and the description states the output current is adjustable from 100mA to 500mA in 1mA increments.

Q: Is this a compact LED driver for space-limited fixtures?

Yes. The product description highlights an ultra-small, thin, and lightweight design with a screwless end cap. Its listed weight is 0.0100 kg, which makes it suitable for applications where low weight and compact form factor matter.

Q: What operating temperatures is this driver rated for?

The specified operating temperature range is -20°C to 50°C. That gives it a defined working range for indoor or enclosed lighting environments that stay within those limits.

Q: What warranty is provided for this model?

The listed warranty period for the Ltech SE-12-100-500-W2D is 5 years. For commercial buyers, that can be useful when evaluating lifecycle cost and long-term maintenance expectations.
