Description
This power supply is a pulse power supply, designed for situations such as micro-arc oxidation that require pulse voltage and current. The power supply adopts a high-frequency isolation design and advanced DSP control, ensuring stable output voltage that does not change due to fluctuations in input voltage. The output frequency and duty cycle are adjustable.
