2.vlf hipot insulation resistance tester feature
1. Data of current, voltage, wave form can be directly sampled at high voltage side, so the data is real and accurate.
2. 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.
3. 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.
4. 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
3.How to choose the suitable products for test
Please make sure that the capacitance of test products is below the instrument rated capacitance. The waveform will be influence if the capacitance of test products is too small and the instrument can not normally output when it below 0.05µF. 0.1µF capacitor in parallel to auxiliary output. Below is capacitance of some instrument for your reference.
