Frequently Asked Questions
What kind of applications is the Ltech SE-20-100-700-W2D designed for?
This model is a 20W constant-current LED driver intended for professional lighting applications that need DALI2 control and tunable white capability. Its compact, thin housing also makes it suitable for space-constrained fixture designs where a lightweight driver is preferred.
What makes this LED driver different from a basic non-dimming driver?
The SE-20-100-700-W2D supports DALI2 dimming and tunable white control, which makes it better suited to projects that need controllable light output rather than simple fixed-output operation. It also supports NFC parameter adjustment, including dimming interface, output current, and DALI address settings.
Can the output current be adjusted on this model?
Yes. According to the product details, parameters such as output current can be changed using an NFC programmer or app and then synced to the driver. The listed model range is 100-700mA, and the product data also notes current can be set as low as 1mA.
Is this driver compatible with DALI-based lighting control systems?
Yes, this model uses DALI2 control and references IEC62386-101, 102, and 209 in the product details. That makes it appropriate for projects that require a driver aligned with standard DALI bus protocols and tunable white control.
What are the key electrical specifications of the SE-20-100-700-W2D?
This LED driver is rated at 20W with a listed output voltage of 48V. The product data identifies it as a constant-current model in the 100-700mA family and also lists a rated current value of 100mA in the supplied record.
Is this LED driver suitable for demanding indoor operating conditions?
It is specified for an ambient temperature range of -20°C to 50°C, which supports use across a broad range of indoor commercial lighting environments. The housing is also described as V0 flame-retardant PC material, supporting applications where material safety is a consideration.
What warranty is offered for this model?
The supplied product data lists a 5-year warranty period for the SE-20-100-700-W2D. That makes it a better fit for commercial and project-based purchasing where longer service life expectations matter.
