Frequently Asked Questions
What kind of LED driver is the Ltech SE-12-350-700-W1DS?
The Ltech SE-12-350-700-W1DS is a 12W constant-current LED driver with selectable output current from 350mA to 700mA. It is designed for dimmable LED lighting applications that use DALI2 control. This model is also described as a Class 2, SELV driver.
Where is this LED driver typically used?
This model is suited to professional LED lighting applications where compact size and DALI2 dimming are important. Its ultra small, thin, lightweight housing makes it a practical choice for space-constrained lighting products and commercial projects. Buyers typically consider it for constant-current LED fixtures rather than general-purpose power supply use.
Does this model support DALI2 dimming?
Yes, the SE-12-350-700-W1DS supports DALI2 dimming. The product description references IEC62386-101, 102, and 207, which aligns it with DALI bus standards. It also includes soft-on and fade-in behavior plus flicker-free dimming performance features in the product description.
What makes this driver different from a fixed-current LED driver?
A key difference is its selectable output current range of 350mA to 700mA, which gives more flexibility than a single-output model. That can help buyers standardize on one driver across more than one constant-current requirement when the application matches this product's ratings. It also combines that flexibility with DALI2 dimming in a compact 12W format.
What operating environment is this driver rated for?
The specified ambient temperature range for this model is -20°C to 50°C. That makes it suitable for applications that need reliable performance across a moderate indoor temperature range. Buyers should verify that their project stays within that stated temperature window.
What are the main physical and warranty details for this model?
The driver has a listed weight of 0.0100 kg, supporting its positioning as a very lightweight unit. Its housing is made from V0 flame-retardant PC materials according to the product description. The listed warranty period for this model is 5 years.
