Product Name:Very Low Frequency (VLF) Testing Equipment

Very Low Frequency (VLF) Testing Equipment

Application

Gold

Product Description:

Very Low Frequency (VLF) Testing Equipment 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.
