- 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.
To use the device, ensure that the power supply meets the requirements of AC50Hz, 220V with frequency stability of fluctuations less than 0.5%. Also, avoid exceeding the rated capacity of the instrument when testing samples, as excessive capacitance can affect the output waveform, with a minimum capacitance of 0.05µF required for normal output. Additionally, it is prohibited to boost voltage without load or connect the device to a resistive load.
