    FAQ

    Q1: What is a variable DC power supply used for?

    The variable DC power supply provides adjustable voltage and current to electronic circuits, devices, and testing equipment. It allows users to safely simulate different operating conditions and test components. Engineers, hobbyists, and students commonly use it for development, troubleshooting, and educational experiments. Its CV/CC modes make it suitable for almost any type of load.

    Q2: How do I switch between constant voltage and constant current modes?

    Most modern variable DC power supplies automatically switch between constant voltage (CV) and constant current (CC) depending on the load. CV mode keeps voltage stable while the current varies. CC mode keeps current stable while the voltage adjusts as needed. Some units also allow manual selection for precise testing.
