Product Features:

  • External I/O output
  • Rapidly assess in as fast as 50 ms
  • Quick discharge of residual voltage
  • Freely configurable test voltage (Set from 25 V to 1000 V, 1 V resolution)
  • Contact check function (Prevents errors due to poor contact)
  • Short-circuit check function (Stops potentional defects from reaching the market)
  • Note: The ST5520 and ST5520-01 cannot be operated alone. Please select and purchase the optional test leads to accommodate your application.

The Hioki ST5520 is the one of the fastest insulation tester in the industry, delivering pass/fail assessment in as fast as 50 ms. 25 to 1000 V test voltage with 1 V resolution.

Industry-beating test time

Rapidly assess in as fast as 50 ms

Testing is complete in as little as 50 ms. This is 700 ms faster than legacy Hioki models.

  • Discharge time varies according to the sample's capacitance
  • The pictured waveform reflects use of a test time of 45 ms
  • The waveform shows the test result for a 9 MΩ, 10 pF sample

High-speed auto discharge function

Quickly discharge residual voltage

The post-test residual voltage discharge time has been reduced significantly compared with legacy models. As a result, when comparing an identical sample under the following conditions, a takt time improvement of 990 ms is estimated.

  • Discharge time varies according to the sample's capacitance
  • The waveform shows the test result for a 9 MΩ, 10 pF sample

Contact check function - Prevents errors due to poor contact

The contact check function allows you to check that proper contact has been made with the device under test prior to the testing. This ensures that resistance testing is not carried out without proper contact, as this can result in erroneous assessment. There are two methods: 4-wire contact check and comparator contact check.

4-Wire Contact Check Continuity between the low contact check terminal and the low output terminal, and between the high contact check terminal and the high output terminal, is verified.

Comparator Contact Check If the comparator result exceeds a previously set upper limit after a normal connection, the instrument reports an "upper fail," indicating a contact failure.

Freely configurable test voltage - Configure from 25 V to 1000 V (1 V resolution)

In insulation resistance testing of lithium-ion and other batteries, the specific test voltage used varies with the manufacturer. In addition, the test voltage for electronic components, such as relays and connectors, is likely to change in the future along with revisions to various standards. ST5520 allows the test voltage to be freely configured.

Comparator Function - Freely set upper and lower limit values

You can select from three types: upper limit, lower limit and upper-lower limit value assessment. Comparator operation can also be delayed for a certain period of time by specifying the preferred response time.

Built-in RS-232C interface

Use the RS-232C interface to capture measurement and assessment results from a PC, PLC or other system. The ST5520 is also equipped with a "data output function" for automatically sending the measurement values and assessment results at the end of each test.
