1.1 Product Overview

The 19020/19021/19022 Multi-Channel Sync Hipot Testers are high quality devices specially
designed to test the hipot leakage current and insulation resistance automatically for
electrical and electronic equipment.
For withstand voltage test, the output power of each channel for 19020/19020-4 is AC:
50VA(5kV, 10mA) /DC: 30VA(6kV, 5mA), for 19021/19021-4 is AC: 48VA(6kV, 8mA) and for
19022/19022-4 is DC: 28VA(8kV, 3.5mA). Thus they can be used to perform withstand
voltage tests on electronic, electrical equipment as well as on components.
For insulation resistance test, the range it can show is 0.1MΩ ∼ 50GΩ and the test voltage is
50V~1000V that can be set as desired. (Note: Only 19021/19021-4 can conduct AC
withstand voltage test.)
The Hipot Tester uses a clear display to show all settings, time, current, voltage, resistance
and memory channel no., etc. without the need to memorize the parameters set previously.
The Hipot Tester has equipped the device to identify pass or fail products as well as to output
signals of test result and to remote control other devices. It has GPIB, HANDLER and RS232
interfaces that are of advantage to automatic test system. This Tester equipped with assorted
devices mentioned above is capable of performing highly efficient and accurate tests for
electrical, electronic equipment and components.

1.2 Features

■
Sync Withstand Voltage Test
The testers have the world's first sync withstand voltage test function that a single device
can have 10 channels to output and test simultaneously and maximum 10 devices can
be controlled (master & slave) for 100 channels. They can be grouped for output to avoid
voltage difference from generation due to adjacent test and furthermore to improve the
production efficiency.
■
Multiple Tests
The testers are able to select single test function such as AC withstand voltage test, DC
withstand voltage test, Insulation Resistance (IR) test and Open/Short Check (OSC) test
■
OSC (Open/Short Check)
The testers have built-in OSC function to check if there is any Open (bad connection) or
Short (UUT shorted) occurred during test. It may cause the Fail product to be identified
as Pass if Open occurs. If Short is detected and resolved early when occurred, it can
reduce the damage to fixture and save the test cost.
