Frequently Asked Questions

What type of LED application is the Ltech SE-12-100-400-W1DS designed for?

Does this model support DALI dimming?

Yes. This model uses DALI2 control and references IEC62386-101, 102, and 207 in the product data. It is intended for lighting systems where precise digital dimming and smooth light adjustment are important.

What output current range does this LED driver offer?

This driver has a selectable constant-current output from 100mA to 400mA. That range gives more flexibility than a fixed-current model when you need to match one driver platform to different low-power LED load requirements.

How do I know if this driver is compatible with my LED load?

This model is suitable for constant-current LED loads that require 100mA to 400mA and stay within the driver's 12W power rating and 50V output limit. If your LED module requires a different drive type or exceeds those limits, this model is not the right match.

What environments is the SE-12-100-400-W1DS rated for?

The listed operating temperature range is -20°C to 50°C. It is also described as a Class 2, SELV LED driver, which makes it appropriate for controlled lighting environments where low-voltage driver safety is a priority.

What are the main specifications of this Ltech LED driver?

This model is rated at 12W with a selectable constant-current output of 100mA to 400mA and an output voltage up to 50V. It also includes DALI2 dimming support, a 5-year warranty, and a compact lightweight design.
