Description
This power supply is a programmable voltage and current source, designed for situations where a voltage and current source starting from 0V is required. 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 voltage is adjustable from 0 to 1500V200A.
