FAQ

What kind of applications is the Ltech SE-30-200-800-W1D designed for?

This model is intended for constant-current LED lighting applications that need dimming control and adjustable drive current. Its 30W output, 200-800mA adjustable current range, and DALI2 dimming make it a good fit for commercial and architectural LED systems where control flexibility matters.

Does this model support DALI dimming?

Yes. This driver is DALI2 dimmable and also includes features such as soft-on and fade-in dimming for a smoother lighting experience. It also supports very deep dimming through T-PWM technology, which helps in applications that need fine light-level control.

What are the key electrical specifications of this model?

This LED driver is rated at 30W with a maximum no-load output voltage of ≤55Vdc. Its rated current starts at 200mA, and the output current can be adjusted up to 800mA depending on the application requirements.

Is the SE-30-200-800-W1D suitable for demanding indoor environments?

It is built with V0 flame-retardant PC housing materials and is specified for operation from -20°C to 45°C. Those characteristics make it appropriate for indoor lighting environments that need a compact driver with a defined operating temperature range.

Does this LED driver offer long-term reliability for commercial projects?

This model includes a 5-year warranty, which supports use in professional and commercial lighting projects where service life matters. Its feature set is aimed at controlled LED applications that need both dimming performance and configurable operation.
