Ltech SE-12-100-400-W1DS 12W 100mA ~ 400mA CC DALI2 LED Driver - Selectable Output

Q: 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.

Q: 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.

Q: 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.

Q: 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.

Q: 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.

Q: 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.
