Features and Advantages
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.
