Verify insulation performance using waveforms and numerical values [waveform display function]

ST5680 is a tester capable of conducting DC withstand voltage testing and insulation resistance testing based on various safety standards.

Not only can it determine the qualification of PASS/FAIL, but it can also display and record the output voltage waveform and leakage current waveform during testing.

Visualizing the analysis of the test helps to trace the source of the inspection.

Output voltage and leakage current displayed in waveform format

The waveform can be used to confirm the direction of the output voltage or leakage current during testing.

While confirming the waveform, the voltage value, leakage current value, and resistance value can also be confirmed in chronological order.

Without the need for a computer, waveform amplification and display operations can be performed, and detailed analysis can be carried out on site.

Advantages of waveform display

Helps optimize production processes

By analyzing the waveform during inspection, it is possible to infer the adverse factors in the production process. By identifying adverse factors and optimizing production processes, production efficiency can be improved.

Helps to analyze the retrieved non-conforming products

You can compare the retrieved non-conforming products with the waveform during the original factory inspection. By optimizing the criteria for determining qualified products, we can further improve production quality.

Helps promote the reliability of inspections

The record management of waveforms is beneficial for the traceability of inspections, building a higher quality inspection system, and enhancing customer trust.

Prevent the leakage of minor faulty products caused by arc discharge [Arc discharge detection function]

Can detect arc discharge caused by welding burrs or dust or foreign objects.

Classifying products that cause minor insulation defects as minor faults can prevent the risk of fire accidents or malfunctions caused by heating after leaving the factory.

Prevent retesting caused by misjudgment [Contact Check Function]

By measuring the capacitance between terminals (stray capacitance, capacitance of the tested object), it is possible to determine whether the detection object is correctly connected.

Prevent misjudging non-conforming products as qualified products

The situation of increased resistance between test parts

Example: Aging of test lines, aging of fixtures or high-voltage relays, etc

Can be easily used

Using two terminals can achieve simple wiring

Suitable for voltage withstand testing of batteries, motors, electronic components, etc

ST5680 is a tester that outputs high voltage to the test object to test its insulation performance. It can conduct safety testing on a wide range of objects from research and development of electronic devices, electronic components, materials, etc. to production lines. In batteries, it is used for voltage resistance testing between the electrodes and the casing of battery modules, battery packs, and cells.

Output voltage Max.8 kV, output current Max.20 mA

Equipped with a DC withstand voltage test mode that measures the leakage current of the test object to evaluate insulation, and an insulation resistance test mode that measures resistance values to evaluate insulation.

In DC withstand voltage testing, the maximum output is 8 kV. Even if the test object contains capacitive components, it can be charged at high speed through a large capacity output of 20 mA, thereby shortening the inspection cycle.

Testing can be conducted without considering the capacitance component

Even if the test object contains capacitive components, due to the design that is less prone to overshoot, it will not output a voltage exceeding the set voltage to the test object, so testing can be carried out with confidence.

In addition, by adjusting the delay time setting, it is also possible to not judge the time when the charging current flows, thereby preventing misjudgment.

The maximum measurable electrostatic capacitance value is 200 nF (measuring larger capacitance values may result in longer measurement time or greater deviation in measurement values). ）

High precision determination with a minimum resolution of 0.001 μ A

With the improvement of insulation performance of batteries and motors, the requirements for setting the current value to determine whether the withstand voltage test is qualified are also increasing, requiring it to be set to a smaller current. If a low resolution voltage tester is used, it is impossible to accurately measure the measured value of leakage current. ST5680 achieves a high-precision specification with a minimum resolution of 0.001uA, allowing for accurate measurement of small leakage currents and determination of qualification.

Equipped with BDV (Insulation Breakdown Voltage) measurement function

Equipped with a BDV (Break Down Voltage) function to confirm the insulation breakdown voltage of the test object.

Increase the output voltage at a certain speed to confirm the voltage at which insulation breakdown occurs.

The testing method follows the standard regulations, including continuous boost testing and step-by-step boost testing.

Both ST5680 tests can be implemented. Can be used for performance evaluation during battery development (insulation endurance assessment).
