Associated Research 5500DT AC Withstand Voltage Tester

The Associated Research 5500DT HypotPlus II AC Withstand Voltage Tester is an AC-only dielectric withstand tester designed for production QA, delivering up to 5 kVAC output with a 20 mA full‑scale current limit and powered from 115/230 VAC. It provides a clean sine‑wave AC output at 50/60 Hz with low distortion (≤1%) and tight output regulation (1% of setting + 5 V), and incorporates ground‑continuity testing to verify insulation integrity before voltage is applied. The unit supports programmable test sequences stored in memory (up to 10 programs), along with remote PLC control inputs (Test, Reset, Memory Select) and status outputs (Pass, Fail, Remote Alarm, Test in Process), enabling automated testing workflows. Dwell and ramp timing are user‑adjustable (0.5–999.9 seconds dwell; 0.5–99.9 seconds ramp), with a password‑protected setup for security and a detachable 7 ft line cord for flexible lab or production floor use. Typical applications include insulation verification and dielectric withstand testing on electronics, medical devices, and other high‑voltage assemblies where controlled AC hipot testing is required.
