FAQ

What type of product is the Ltech SE-12-100-500-W1D?

The Ltech SE-12-100-500-W1D is a 12W constant-current LED driver for lighting applications that need dimming control. This model is designed for adjustable output current and supports DALI2 dimming, with NFC-based parameter configuration through an app.

What output range does this LED driver support?

This model supports an adjustable output current range of 100-500mA and a maximum no-load output voltage of ≤48V. Its total power rating is 12W, so it is best suited to low-power LED lighting applications that fit within those limits.

Does this driver support DALI dimming?

Yes, this driver is DALI2 dimmable. It also includes soft-on and fade-in dimming behavior, and the description highlights T-PWM super deep dimming technology with 0.01% dimming depth.

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

This model stands out because it combines DALI2 dimming with NFC app-based parameter adjustment. It also allows changes to output current, DALI address, groups, and scenes, which gives it more flexibility than a fixed-output, non-dimmable driver.

Can this driver be adjusted without replacing the unit?

Yes, the product description states that output current, DALI address, and other parameters can be changed through the app. It also notes 1mA step adjustment, which is useful when a project needs fine current tuning within the supported range.

What operating environment is this driver rated for?

This driver is specified for ambient temperatures from -20°C to 50°C. It features an IP20 protection grade, making it suitable for indoor use only.
