    FAQ

    Q1: What are the main advantages of the 0ā€“120V high-voltage variable DC power supply?

    With a maximum output of 120V, this supply is suitable for higher-voltage test and power supply applications, including high-voltage electronic module testing, specialized motor drives, industrial equipment requiring elevated DC voltage, and R&D of medium-voltage power systems. It offers stable output and precise adjustment for demanding high-voltage applications.

    Q2: What installation and operational rules must be followed for a 120V output?

    The 120V output requires strict adherence to electrical safety standards. All connections must be insulated, and the equipment must be properly grounded. The working area should be kept dry and clear of conductive materials. Users should avoid open connections and regularly check for loose terminals to prevent arcing or electric shock.
