KPM offers the most portable and easy to use VLF hipots available in market. A VLF hipotis just an AC
output tester but with an output frequency of 0.1 Hz or lower rather than 0.1 Hz. Although the frequency is
very low, it is still an alternating current with polarity reverses after every half cycle. At 0.1 Hz output,
rather than 50Hz, it takes 500 times less current and power to apply an AC voltage to a capacitive load, like
a long cable.
KPM product combines modern advanced digital variable frequency technology and micro computer
control together, therefore, it can realize
• Fully automatic voltage boost,
• Step down,
• Measurement and protection as well as the manual intervention in the process of automatic
voltage boost.

Key specifications :
• Small size
• Light weight
• Big Display. 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.
• 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.
. • 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.
• 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.
