HVLF-80kV Portable VLF Test Set

Mode: HVLF-80kV
Rated Voltage/current: 80kV/30mA (Peak)

Introduction: 
The product combines modern advanced digital variable frequency technology and micro computer control together, therefore, it can relize the full automatic voltage boost, 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 visual display, and can display the output wave form. The printer outputs test reports.

Features: 

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. Overcurent protection: It is high-low voltage dual protection in the design, the accurate shutdown 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 resister is provided in the voltage boost body in the design and this eliminates the need of additional protective resister connected outside.

Wiring Method of connection in series：

The product with series-type structure is a new one improved by our company based on the original single structure. Its volume and weight are reduced and can be used for many purposes. In single connection, rated output voltage is 30kV; in series, the rated output voltage is 80kV.
