FAQ
What kind of LED applications is the Ltech SE-12-100-400-W1A designed for?
The Ltech SE-12-100-400-W1A is a constant-current LED driver intended for low-power LED lighting applications that need adjustable output current. With a 12W power rating and a 100mA to 400mA output current range, it fits projects where matching the driver to the LED load is important.
What are the main electrical specifications of this LED driver?
This model is rated at 12W with a listed output voltage range of 10-42Vdc and a rated current range of 100mA to 400mA. The product name indicates a constant-current range of 100mA to 400mA, which helps distinguish it from fixed-output drivers.
Does this model support dimming?
Yes, this driver is positioned as a dimmable model, and the product data lists the dimming interface as 0-10V (1-10V/10VPWM/RX). For buyers comparing dimming options, this makes it more suitable than a non-dimmable constant-current driver in lighting systems that require light level control.
Is the SE-12-100-400-W1A suitable for demanding environments?
It is specified for operation from -30°C to 50°C, which supports use in a wide range of indoor and protected commercial lighting environments. The description also highlights a V0 flame-resistant polycarbonate housing, which is relevant for buyers concerned about material durability and safety-oriented construction.
What type of LED load is this driver compatible with?
This model is intended for constant-current LED loads rather than constant-voltage products. Buyers should evaluate it against LED systems that need a driver in the 100mA to 400mA constant-current range and align with the listed 10-42Vdc output specification.
How does this driver differ from larger LED drivers?
This is a compact 12W model built for lower-power applications, not a higher-wattage driver for larger LED loads. Its small size, light weight, and adjustable constant-current range make it a more targeted choice when a larger driver would be unnecessary.
What warranty is offered for the Ltech SE-12-100-400-W1A?
The listed warranty period for this model is 5 years. That gives commercial and project buyers a longer coverage window than many short-term electronics components, which can be relevant when evaluating lifecycle cost.
