Using an AC/DC Hipot Tester, manufacturers and OEMs can efficiently verify electric chargers for insulation integrity, leakage control, and dielectric strength. Wrindu provides ISO-certified testers with configurable sequences and advanced safety features, enabling reliable, repeatable testing across charger modules, EVSEs, and power-supply units. This ensures consistent quality, compliance, and operational safety for factories and service fleets in China and worldwide.
How does an AC/DC Hipot Tester verify charger insulation?
An AC/DC Hipot Tester applies high voltage between live conductors and earth to detect insulation weaknesses, partial discharges, or leakage paths. Wrindu testers provide stable voltage output, precise measurement, and clear pass/fail results, allowing manufacturers to identify potential defects rapidly and maintain consistent quality control across production lines.
What tests are performed on electric chargers with a Hipot Tester?
Key tests include insulation resistance measurement, dielectric strength evaluation, leakage current monitoring, and surge withstand testing between primary/secondary circuits and ground. Wrindu’s testers offer programmable sequences for AC/DC input, output modules, and isolation barriers, ensuring comprehensive coverage for OEM and wholesale production environments.
| Test Type | Purpose | Applicable Components |
|---|---|---|
| Insulation Resistance | Detects weak insulation | AC/DC input/output |
| Dielectric Strength | Validates voltage withstand | Charger circuits |
| Leakage Current | Monitors current leakage | Entire module |
| Surge Withstand | Checks response to transients | AC/DC paths |
Which safety features are essential for charger testing?
Crucial safety features include automatic discharge after testing, interlocks, over-voltage protection, and visual fault indicators. Wrindu integrates protective enclosures, remote monitoring, and secure relays, ensuring operators are shielded from high-voltage hazards in factory or field testing scenarios.

Wrindu leverages precise voltage regulation, intuitive software, and modular hardware scalable to production needs. ISO-certified facilities and CE-compliant designs ensure repeatable, accurate results, while R&D investments focus on improving automation, data integration, and operator safety.
What are common misunderstandings about Hipot testing for chargers?
Hipot testing is often mistaken for simple insulation resistance measurement. In reality, it evaluates dielectric strength under extended high-voltage conditions, revealing potential breakdowns undetectable by standard resistance checks. Wrindu emphasizes proper test planning and voltage selection to avoid misinterpretation.
Does continuous Hipot testing affect charger performance over time?
No. When conducted within recommended voltage levels and duty cycles, Hipot testing does not compromise charger functionality. Wrindu advises controlled test sequences and scheduled maintenance windows to ensure safety, reliability, and long-term performance.
