    FAQ

    Q1: Can I use linear adjustable DC power supply for LED testing?

    Yes, linear adjustable DC power supply is ideal for LED testing. It delivers stable, precise DC output, which aligns perfectly with LED operation. Just ensure the supply’s voltage range matches the LED specs to avoid overload, then gradually adjust the voltage within the safe operating range while monitoring brightness, color accuracy, and function. This creates a controlled environment for accurate evaluation, though linear supplies are generally less energy-efficient than switching types.

    Q2: What should I pay attention to before turning on linear DC power supply?

    Before turning it on, please turn the voltage and current knobs to the minimum, check whether the positive and negative poles of the wiring are correct and whether there is a short circuit, confirm that the load parameters match, and ensure that the equipment is well-ventilated and there is no fault alarm before turning it on.
