Intelisens ST-AC Series
Proton Products InteliSENS® ST-AC series mains frequency spark testers meet the international standards stipulated for wire insulation testing UL1581, UL2556 and EC62230. The Proton Products mains frequency AC Spark Testers are designed for in-line testing of cables to detect pinhole and bare patch insulation faults. They accommodate cables up to 130 mm in diameter and outputs an AC frequency, user-adjustable EHT test voltage of up to 25 kV AC (rms). Typical applications are for the insulation testing of power and automotive cables. This unit offers a broad selection of built-in and optional industry-standard communications interfaces for connection to production controllers. The InteliSENS® ST-AC Series electronics are housed in a rugged IP54 sealed stainless steel case, ensuring reliability and long operational life.
