Product Details
2019 New 60kv VLF AC Withstand High Voltage Tester/ VLF Hipot
Tester Manufacturer Direct
The product combines modern advanced digital variable frequency
technology and micro computer control together, therefore, it can
realize the full automatic voltage boost, stepdown, measurement and
protection as well as the manual intervention in the process of
automatic voltage boost. The full electronic design ensures the
small size and light weight. The big LCD screen ensures the clear
and visual display, and can display the output wave form. The
printer outputs test reports. In addition, the product has features
as follows:
- 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.
