FAQ
What type of LED load is the LTECH SE-15-350-700-G1T designed for?
This model is a constant-current Triac LED driver intended for LED applications that require a regulated output current rather than constant voltage. It is designed for use with compatible constant-current LED loads within its rated 15W power capacity and up to 50V output.
What are the main electrical ratings of the SE-15-350-700-G1T?
The SE-15-350-700-G1T is rated for 15W output power and a maximum output voltage of 50V. Its output current range is 350mA to 700mA, providing constant current regulation for compatible LED loads.
Does this LED driver support phase-cut dimming?
Yes, this model uses AC phase-cut dimming control and is identified as a Triac LED driver. That makes it suitable for projects where phase-cut dimming compatibility is required at the driver level.
What temperature range is this driver rated for?
The specified operating temperature range is -20°C to 45°C. Buyers should make sure the installed environment stays within that range for normal performance and product longevity.
What makes this model different from a constant-voltage LED driver?
The SE-15-350-700-G1T is a constant-current driver, so it is intended for LED loads that are specified by drive current instead of a fixed output voltage. Unlike a constant-voltage driver, this model regulates current and provides up to 50V output as needed within its rated operating limits.
What build and durability features does this driver include?
The SE-15-350-700-G1T features a compact, lightweight form factor with dimensions of 111×35×20mm. It includes overload, overheat, and short circuit protection, automatically recovering once conditions normalize.
