HypotULTRA II combines the three most common dielectric safety tests (AC Hipot, DC Hipot & IR test) required by agencies such as UL, CSA, IEC, VDE, TÜV, BABT and others into a single 19” rack mount cabinet which takes up less rack space and allows for testing through a single DUT (Device Under Test) connection. QUADCHEK®II includes the same tests as HypotULTRA®II along with a high current Ground Bond test for applications requiring a test of the safety ground circuit
