FAQ

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

The Ltech SE-12-100-400-W1DS is a 12W constant-current LED driver for lighting applications that need a selectable output current between 100mA and 400mA. It is intended for low-voltage LED loads that operate within the driver's output limits and benefit from DALI2 dimming control.

Does this model support DALI dimming?

Yes. This model uses DALI DT6 control. 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 an IP20 rated device, making it appropriate for controlled indoor lighting environments.

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.
