DC HIPOT TESTER ST5680A

Product Description

The HIOKI ST5680A is a professional DC Hipot Tester designed for reliable electrical safety and insulation testing of EV battery cells, modules, packs, and other high-voltage equipment. It combines DC withstand-voltage testing, insulation-resistance measurement, and breakdown-voltage testing in one instrument. The tester provides DC output up to 8 kV with a maximum test current of 20 mA, making it suitable for demanding high-voltage safety tests. It also offers very fine current measurement resolution down to 0.001 µA for detecting small leakage currents. A major feature is its built-in waveform analysis, which records voltage, current, and insulation-resistance waveforms at up to 500 kS/s and for up to 128 seconds. Arc detection and capacitance-based contact checking help identify insulation problems and prevent false PASS results caused by poor connections. The ST5680A is designed for safe and repeatable production and laboratory testing, with automatic discharge, interlock, voltage limitation, auto-ranging, panel memory, and USB/LAN connectivity. It is particularly suited to EV battery manufacturing, R&D, quality control, and high-voltage insulation testing.
