The output voltage and current of this series of DC charging power supply can also be set arbitrarily, which has strong flexibility, constant current and constant voltage functions, and has the good characteristics of small output ripple. It is suitable for the withstand voltage life test of various specifications of electrolyte capacitors and bile electrolytic capacitors, as well as capacitor aging. Each group has short-circuit protection function, which well protects instrument operators and aging or experimental capacitors.
