Hioki BT5525 Battery Insulation Tester, 500 Vdc with USB, LAN, GPIB and Analog Output

Hioki BT5525 Battery Insulation Tester, 25 to 500 Vdc with USB, LAN, GPIB, and Analog Output

The BT-5525 is an insulation resistance tester that generates DC voltage and tests the insulation resistance of instruments, parts, batteries, etc. It’s capable of high-speed testing using user-configured test voltages. With the Break Down Detect (BDD) function, micro short circuits and contaminations (metal foreign substances) can be detected during an insulation resistance test before battery liquid injection. In addition, this instrument can be widely used in manufacturing/test lines for research and development since ample communications interfaces are provided as standard equipment.

With the Measurement and Charging Current Limit Function, the charging current can be limited from 50 μA to 50 mA as desired; settings can be adjusted to achieve the optimal test time for the device under test (DUT) with a capacitive load.

Any test voltage can be set between 25 V and 500 V with a resolution of 1 V. With the comparator function and test time function, insulation resistance tests can be performed in accordance with various standards.

Contact check function for detecting contact defects and broken wiring connections. The contact condition is checked by monitoring the electrostatic capacitance between test points. This function helps improve the test quality.

The Automatic discharge function, after the test, discharges the electric charge stored in the DUT into the instrument, which can prevent damage to other instruments during the next test.

*The instrument is not able to perform measurements by itself. Please purchase optional test leads separately as appropriate for your measurement application. The LOW terminal is a dedicated HIOKI connector, so only the optional L2131 or L2133 can be connected.
