, The series resonant variable frequency test instrument is also known as the transformer volt-ampere characteristic tester.

1. The instrument is safe and convenient to operate. It is a fully microcomputerized device with a built-in high-performance imported CPU, ensuring high reliability. After setting the test values according to the interface prompts, there is no need for manual contact with the tested equipment. The instrument automatically completes the test, keeping test personnel away from high-voltage circuits and ensuring their personal safety.

2. The output capacity is large. The maximum output voltage for volt-ampere characteristic tests is up to 1000V, and the maximum current for transformation ratio tests is up to 600A. The instrument's output capacity is 5KVA.

3. Optional accessories include an external voltage booster, an external current booster, and an external voltage regulator. The external voltage booster can increase the voltage up to 2000V, 3A; the external current booster can increase the current up to 1000A; and the external voltage regulator can provide a maximum output of 1500V, 20A. When using the external voltage booster, volt-ampere characteristic tests can be performed on current transformers up to 500KV class with 1A current.

4. The large 320*240 dot matrix Chinese character graphical interface clearly displays the volt-ampere characteristic curve after the test, which is clear, aesthetically pleasing, and easy to analyze. It comes with a built-in micro printer that can print curves and test results at any time.

5. The instrument uses a rotary mouse as the input device, making operation convenient and simple, with a long service life.

6. The instrument has built-in Flash memory, so data is not lost after power failure. After on-site tests, test results can be viewed and printed indoors.

7. The instrument is equipped with an RS232 communication interface, allowing connection to a computer via a serial cable for communication between the PC and the instrument. Test personnel can use the computer to control the instrument for testing or upload test data from the instrument. The PC application software provided with the instrument is powerful, aesthetically pleasing, and easy to operate. It can save and print test results and export test data as EXCEL documents for editing.

8. The instrument's power supply supports adaptive AC220V and AC380V input.
