Features:
★ Data of current, voltage, wave form can be directly sampled at
high voltage side, so the data is real and accurate.
★ Overvoltage protection: If the output exceeds the set limit of
voltage, the instrument will shut-down to protect itself, the
actuation time is less than 20ms.
★ Overcurrent protection: it is high-low voltage dual protection in
the design, the accurate shut-down protection can be made according
to the set value at high voltage side; If the current on low
voltage side exceeds the rated current, the instrument will take
shut-down protection, the actuation time are both less than 20ms.
★ A high voltage output protective resistor is provided in the
voltage boost body in the design and this eliminates the need of
additional protective resistor connected outside
