Description
TH9201 Provide 5kVAC/30mA withstanding voltage, 6kVDC/10mA withstanding voltage and
insulation resistance tester.
TH9201S Provide 5kVAC/30mA withstanding voltage, 6kVDC/10mA withstanding voltage
and insulation resistance with scanning test.
TH9201B Provide 5kVAC/20mA withstanding voltage, 6kVDC/5mA withstanding voltage and
insulation resistance test.
TH9201C Provide 5kVAC/20Ma withstanding voltage test.
In high voltage modular, there is a AB power amplifier power which can assure the
programming of output voltage as well as the isolation of output voltage power and line power.

～
600Hz high voltage transformer can rise voltage, and use high voltage feedback loop to
assure the accuracy of output voltage, then the actual voltage adjustment rate is far smaller
than that of transformer, which can be used to the product whose VA is larger than the actual
power.
In AC output, set the operation in 50 or 60Hz
，
not being limited by line voltage, the voltage
waveform isn’t affected by line voltage neither. The instrument also has the real current test,
and then the large current generated by distributed capacitance can’t affect the judgment of
real insulation.
To DC and insulation resistance test, TH9201/S/B tester use 600Hz AC to form DC
voltage to be the power, which can assure the DC power ripple is far less than the formal
withstanding voltage tester, thus to assure the stability of 5000V, 10mA test.
Once connecting the load, TH9201 not only can perform the independent AC withstanding
test, DC withstanding voltage test, insulation resistance test, but also multi –item test via the
setting of test programme. When connecting with high voltage scanner TH9121, perform
multi-items and multi-products test via setting the item of test programme. Each scanner can
adopt 8 channels. The tester can be connected to two scanners, reach to 16 channels totally.
TH9201 series all allocate PLC interface, RS-232C
、
GPIB(optional)
，
thus the instrument
can adapt to the auto test system of different required safety and reliability.
Feature
：
■
3 test functions—AC withstanding voltage test, AC withstanding voltage test and
insulation resistance test.
TH9201/S/B provides AC withstanding voltage test and insulation resistance test.H9201C
provides AC withstanding voltage test.
Once connected with load, the tester can perform different tests continually.
