■ Accurate testing
based on standards Withstand voltage tests based on various standards can be carried out, accurate testing can be performed by pass / fail judgment function and timer function that compare by setting upper and lower limits of test.
In the withstand voltage test, the voltage comparison function does not start the test until the output voltage set by the voltage control knob is within ± 5% of the reference voltage value (output voltage ≦ 1 kV: ± 50 V) I can do it.
■ Fluorescent display tube The
fluorescent display tube is excellent in visibility and it is very easy to see, so you can check the test status and test results accurately and quickly.
■ Analog voltmeter (Withstand voltage test only) The
test voltage is digitally displayed on a fluorescent display tube, and it can be confirmed with an analog voltmeter.
■ Zero closing switch (withstanding voltage test only) It
controls the ON / OFF of the output voltage at the zero-crossing point and prevents damage to the EUT, even if the EUT is faulty.
■ Saving at the time of
test setting In order to quickly switch the test settings specified in the various standards and laws, the function to save the test setting value is provided, and it is possible to save up to 20 setting values in each test mode I can do it. Also, since the set value just before shutting off the power is saved, the previous setting will be reproduced when the power is turned on.
■ EXT-I / O
EXT-I / O outputs signals according to the state of TWV-551. You can also input start and stop signals.
■ Automatic testing and test results can be captured using the RS - 232C interface computer.
■ Status Out In
accordance with the status of TWV - 551, perform relay contact output from the terminal block on the rear panel.
