FAQ

What type of LED load is the LTECH SE-9-350-700-G1T designed for?

This model is a constant-current LED driver intended for LED loads that require controlled current rather than constant voltage. It is part of LTECH's CC Triac driver range and is suited to low-power LED lighting applications within its stated electrical limits.

What dimming method does the SE-9-350-700-G1T support?

The SE-9-350-700-G1T supports AC phase-cut dimming, commonly referred to as Triac dimming. That makes it a fit for applications where phase-cut dimming compatibility is required from the driver itself.

What are the main electrical specifications of this LED driver?

The SE-9-350-700-G1T supports an output power range of 0.7W to 8.4W with an output voltage range of 2-12Vdc (max ≤22V). The listed output current range is 350-700mA, identifying it within LTECH's constant-current Triac driver series.

What makes this driver different from a constant-voltage LED power supply?

The SE-9-350-700-G1T is a constant-current driver, so it is intended for LED loads that are specified by drive current rather than by a fixed output voltage supply. Buyers comparing it to constant-voltage power supplies should match it only to fixtures or modules that call for a constant-current driver.

What operating temperature range is this driver rated for?

This LED driver is rated for ambient temperatures from -20°C to 45°C. That range is important when evaluating whether the product is suitable for the intended operating environment.

What physical and durability features does the LTECH SE-9-350-700-G1T offer?

The SE-9-350-700-G1T features a compact and lightweight form factor with dimensions of 111×35×20mm. It includes protections for overload, overheat, and short circuit, with automatic recovery for overload and short circuit conditions.
