Constant Current Led Driver 700ma

Constant current LED drivers are designed for a designated range of output voltages and a fixed output current (mA). LEDs that are rated to operate on a constant current driver require a designated supply of current usually specified in milliamps or amps.

Constant current led driver 700ma


When using LEDs as displays or other lighting devices or backlights, they need to be driven with constant current. The main reasons are:

1. Avoid driving current exceeding the maximum rating and affect its reliability.

2. Obtain the expected brightness requirements and ensure the consistency of brightness and chromaticity of each LED.

3. Can effectively avoid lightning strikes, grid surges, over current, over voltage protection, so that LED life is longer.
