Feature：
■ Four test functions—AC withstanding voltage test, DC withstanding voltage test, and
insulation resistance test, open and short detection.
TH9310, TH9320 provide AC/DC withstanding voltage test and insulation resistance test.
TH9310B provide AC withstanding voltage test.
All the instruments have the open and short detection function.
Once connected with load, the tester can perform different tests continually.
■ Multi-channel function
TH9320-S4/S8 has 4/8 programmable test channels. With appropriate test fixtures,
program-controlled and fast connection of components can be realized, and the test speed of
multi-parameter measurement can be greatly accelerated.
Simultaneously, the following functions can be achieved:
1. Combine into the TH90010 test system: connecting with the TH2882AS, use the withstand
voltage channel to switch the inter-turn voltage test. At the same time, the withstand voltage and
inter-turn withstand voltage sequential test capability can be achieved by programming.
2. Perfect contact check (node link check): Use two channels to connect one node at the same
time to conduct the continuity test and implement instrument-to-node connection reliability
testing.
■ Two different test power selection
In TH9320 series high voltage module, there is a AB power amplifier circuit and a 100VA high
voltage transformer, which can realize the output of 5kV/20mA (AC) and the output of 6kV/10mA
(DC). The distortion of the waveform is less than 3%.
In TH9310 series high voltage module, there is a AB power amplifier circuit and a 50VA high
voltage transformer, which can realize the output of 5kV/10mA and the output of 6kV/5mA (DC).
The distortion of the waveform is less than 3%.
If continuous current output is set, in order to guarantee the reliability of the instrument, the
maximum output time is 60 seconds when the output is more than 60% of the rated output current.
If the output is within 60%~40% of the rated output current, the continuous working hours should
be limited. If the output is less than 40% of the rated output current, it can ensure continuous
working.
