other functions can be controlled
remotely. In DC withstanding voltage test, AC withstanding voltage test and insulation
resistance test, judge and time can be controlled remotely. The test result can also be
read via remote control. GPIB and RS-232C interface provides a stable and united
standard test interface for PC or other devices.
■
High voltage scanner can realize the control function flexibly
TH9201S have internal multi-channels, in withstanding voltage test and insulation
resistance, it can control 8 channels to test 8 points. Each channel can be connected to
HI/LO/OPEN voltage. TH9201 series can be connected with TH9121 multi-channels
scanner with 8 channels. TH9201 series can be connected with 2 scanners at most to
operate 16 channels simultaneously.
■
Rising time control function
In AC withstanding voltage test, DC withstanding voltage test and insulation resistance test,
the test voltage can be raised to set value slowly, it can’t provide set voltage to DUT
instantly after test starts. The resolution is 0.1s from 0.1s to 99.9s
，
and the resolution is
from 100s to 200s. TH9201series meet each UL test standard and IEC withstanding
voltage standard
（
primary voltage is less than the half of test voltage and it can appoint the
fixed rising time when reaching the set test voltage.
■
Fall time control function
In the pass judge of AC withstanding voltage test, the test voltage can be reduced gradually.
The voltage fall time can be set within 0.0s to 99.9s

■
Discharge function
In common condition, the DUT reacts the feature of capacitance. At the moment of the cut
of DC withstanding voltage and insulation resistance test, the DUT holds the full charge
status, so there is a danger of electric shock..TH9201 has the enforced rapid discharge
function after DC withstanding voltage test and insulation resistance test finish.
■
Reinforced safety
In order to improve the safety, TH9201series allocate many devices and safe functions
including safe output terminal, discharge function and electric wall. The electric wall means
