AC withstand voltage test, and insulation resistance test can be remotely controlled. Test
results can also be read from behind through remote control. The USB and RS-232C
interfaces provide a stable and standardized standard test interface with PCs or other devices.
HANDLER interface for easy connection control
HANDLER
interface: You can input
START, STOP
signal, and output
TEST, PASS, FAIL
signals. Can be connected to the foot switch easily, connect with simple test fixtures for safety
interlocks, pneumatic controls, test indications, and more. Internal or external 24V power
supply can be used as the output interface power supply for easy control and connection.
USB interface for backup
The instrument is equipped with a USB interface, which can save the test files written by the
instrument and customer measurement files to an external USB flash drive, or load the files
from a USB to the instrument to conveniently set the usage parameters and archiving scheme
of the instrument in batches.
Test waiting time setting
The test waiting time can be set from 0.1s to 999.9s with a resolution of 0.1s. During this time,
the instrument will output a test control signal to control the external device to ensure reliable
test connection, and then start the high voltage test process.
Rise time control function
In AC withstand voltage test, DC withstand voltage test and insulation resistance test, the test
voltage can slowly rise to the set value instead of providing the set voltage to the DUT
immediately after starting the test. The voltage rise timecan be set from 0.1s to 999.9s with a
resolution of 0.1s. ST9010 series meets various UL test standards and IEC withstand voltage
test standards. (Rise time can be specified when the initial voltage is less than half of the test
voltage and when the set test voltage is reached).
Drop time control function
In the qualification judgment of the AC withstand voltage test, the test voltage can be
gradually reduced. The voltage drop time can be set between 0.1s and 999.9s with a resolution
of 0.1s.
Discharge function
Usually the tested part is capacitive. At the moment when the DC withstand voltage test and
the insulation resistance test are cut off, the DUT remains fully charged, therefore there is a
danger of electric shock. The ST9010 series has a forced fast discharge function on the DUT
after the DC withstand voltage test and insulation resistance test are completed.
Enhanced security
For improving safety, the ST9010 Series is equipped with many facilities and safety features,
include safety outputs, discharge function and ground current detection. The so-called ground
current detection is that when the return current of the ground high voltage test circuit is
greater than 0.5mA through the chassis, high voltage output is cut off.
Higher test accuracy
ST9010 series voltage digital display, voltage test accuracy is ± (1% reading + 5V) during
withstand voltage test, voltage accuracy is ± (2% reading + 5V) during insulation resistance
test. The accuracy in the withstand voltage and current test is ± (2% r 5 digits).
Current clear function
AC and DC withstand voltage test requires high voltage and high current sensitivity, the
