0.1Hz integrated ultra-low frequency and high voltage generator

The withstand voltage test can be classified into the AC withstand voltage test and the DC withstand voltage test. The AC withstand voltage test can also be divided into power frequency, frequency conversion and 0.1Hz ultra-low frequency test technologies. The 0.1Hz ultra-low frequency technology is the latest technology and is the technology recommended by IEC (International Electrotechnical Commission) at present. The new generation of VLFS series microcomputer type 0.1 Hz ultra-low frequency high-voltage generators are core products independently developed by FARSEE,they overcome many shortcomings of mechanical domestic products, and its cost performance is much higher than the similar imported products. It is particularly suitable for the withstand voltage test of electrical equipment (e.g.: power cables, power capacitors, large- and medium-sized generators and motors, etc.) with large insulation equivalent capacitance

1、Advanced technology: By adopting digital frequency conversion technology and microcomputer control, the test procedures of boosting, voltage reduction, measurement, protection, etc. are fully automated. The instrument has the electronic calendar function, and the time can still be maintained after powering down.

2、Convenient operation: Simple wiring, and fully automatic operation.

3、Comprehensive protection: Multi-protection (over-voltage protection, over-current protection on high- and low-voltage side), rapid action (action time ≤ 20 ms), the instrument is safe and reliable.

4、Safe and reliable: The controller and the high-voltage generator are in low-voltage connection and under photoelectric control, which are safe and reliable to use.

5、By adopting high- and low-voltage closed-loop negative feedback control circuit, the output has no capacitive rise effect.

6、Complete configuration: 8-inch industrial touch screen, manual storage, and manual printing.

7、The instrument has the data communication function. It can be connected to a computer through a USB port for uploading test data to the computer.

8、The instrument has the help documentation function, through which the directions for use, wiring and notes of the instrument can be known without viewing the instruction book.

9、The instrument has the system setting function, through which the current time can be modified.

10、Large test range: Multi-frequency selection of 0.1Hz, 0.05Hz and 0.02Hz, a large test ange.

11、Small size and light weight: Very conducive to outdoor operations.
