Associated Research 4040AT Hypot Test Instrument

Associated Research 4040AT Hypot Test Instrument is an AC high-potential tester and ground-continuity test set for production-line electrical safety testing. It delivers 0–3 kV AC hipot output at up to 15 mA, enabling dielectric withstand tests on components and assemblies to meet UL, CSA, VDE, BSI, and IEC requirements. The unit runs on 120 VAC, 50/60 Hz, at about 1 A, and includes an audible and visual failure detector with SPDT relay contacts that switch on a fault, allowing integration with alarms or control systems. In addition to hipot testing, the 4040AT supports ground-continuity checks to verify grounding integrity of the device under test, a common requirement in manufacturing for safety-critical products. Designed for production environments, this model supports repetitive testing in quality assurance workflows that require verified insulation and grounding results before final assembly or shipment.
