Bring additional inspection performance to safety testing. Accelerate battery quality improvements with waveform analysis. Product concept Growing adoption of electric vehicles (EVs) and self-driving technology is leading to more rigorous reliability requirements for automotive components, pushing up quality.Degradation of EV batteries and related issues can lead to serious accidents, including fire.Consequently, safety and quality control are becoming even more important than in the past. Market requirements “Manufacturers want to manage test results using waveform data to verify battery quality.” “Manufacturers want to conduct shipping inspections (DC withstand voltage tests) that comply with a range of international standards.” The ST5680 is a DC Hipot tester that was developed to meet these battery market requirem

Preventing the shipment of batteries with latent defects that could lead to fires. Test waveform display Detection of minuscule defects Prevention of erroneous judgments Waveform display function Verify insulation performance with waveforms and values. The ST5680 is a DC Hipot tester that can perform DC withstand voltage testing and insulation resistance testing in compliance with a variety of safety standards. In addition to generating PASS/FAIL judgments, the instrument can display and record applied voltage waveforms and leakage current waveforms acquired during testing. Its ability to visualize...

Arc discharge detection function Prevent minuscule failures due to arc discharges. The ST5680 can detect arc discharges, which are caused by residual materials like burrs and cuttings. By correctly identifying parts with minuscule insulation defects as defective, the instrument helps prevent the risk of hazards such as fires and accidents caused by heating after shipment. Contamination with foreign material during the production process Detection of arc discharges triggering a FAIL judgment Detection of parts with minuscule defects + Burrs at a weld location Foreign material between cells The...

High-performance model specifically designed for DC withstand voltage testing High output High stability Detection of minuscule currents Featuring testing quality that’s a step above. Accommodate the full array of DC withstand voltage testing applications with specs that comply with a broad range of international standards. Ideal for withstand voltage testing of batteries, motors, electronic components, and other parts The ST5680 tests insulation performance by applying a high voltage to the test target. It’s capable of performing safety testing for a broad assortment of targets, including electronic...

Power supply performance that satisfies test conditions defined by international standards Output voltage: Max. 8 kV Output current: Max. 100 mA The ST5680 provides two modes: DC withstand voltage test mode, which evaluates insulation by measuring the leakage current in the test target, and insulation resistance test mode, which evaluates insulation by measuring resistance. In DC withstand voltage testing, it can output up to 8 kV, one of the highest values for any instrument of its kind. Test cycle times can be reduced since it can charge test targets quickly with high-capacity, 100 mA output,...
