FAQ
What type of LED driver is the LTECH SE-12-350-700-W1D?
The LTECH SE-12-350-700-W1D is a 12W constant-current LED driver with DALI2 dimming support. It provides selectable output current from 350mA to 700mA, making it suitable for projects that need one driver model across different current requirements.
Is this driver suitable for DALI lighting control systems?
Yes. This model uses a DALI dimming interface. It is designed for applications where integration with DALI-based lighting control is required.
What makes this model different from a fixed-output LED driver?
The key difference is its selectable constant-current output from 350mA to 700mA. That gives more flexibility than a fixed-current driver when matching one model to different compatible LED loads within the product range.
Can this LED driver support smooth low-level dimming?
Yes. The SE-12-350-700-W1D supports 0 to 100% dimming and states LED start at 0.01% is possible. It also specifies flicker-free dimming across 0 to 100% in line with IEEE 1789.
What kinds of lighting applications is this model intended for?
This model is suitable for internal lights application. It is a fit for indoor LED lighting projects where constant-current output and DALI dimming are required.
What operating environment is this driver rated for?
The specified operating temperature range is -30°C to 50°C. That makes it appropriate for indoor environments where the ambient conditions stay within that range.
What protection and reliability features does this driver include?
This model includes overload, overheat, and short-circuit protection with automatic recovery. It also states innovative thermal management and intelligent power life protection.
