HypotULTRA III is a fully-automated dielectric analyser for Safety Agency production line testing. The HypotULTRA III family features two models.

The 7620 is an AC Hipot with an optional 4 or 8 channel internal scanning matrix. The 7650 is a 3-in-1 system that performs AC Hipot, DC Hipot and Insulation Resistance tests. An optional 4 or 8 channel internal scanning matrix is also available.

HypotULTRA III can be used as a bench top instrument or as a PC controlled system. It is well suited for all hipot testing applications. An additional continuity test mode allows the HypotULTRA III to perform both point-to-point continuity and hipot tests at voltages up to 5,000 volts. Both models feature an enhanced graphic LCD with an analog bar graph, which allows users to monitor test results versus limit settings. HypotULTRA III is an easy-to-use dielectric analyser with advanced technology and test capability.

Key features

The Ethernet card allows customers to remotely set up and execute tests and retrieve data from a PC with a network connection. The card also allows for barcode scanning and provides an active RS-232 serial port.

The patented SmartGFI® is a high speed shut down circuit that provides maximum operator protection. If the circuit detects excessive leakage to ground it shuts down the high voltage in less than 1 millisecond. SmartGFI is automatically activated if the DUT is not grounded. The operator does not need to make the decision whether to activate the SmartGFI.

This drop in interface simulates the interface found on HypotPLUS II and provides manufacturers the ability to install HypotULTRA III into analog controlled test systems. The analog signal provides access to the same voltage and current controls as found on HypotPLUS II.

The patented CAL-ALERT® feature automatically alerts the user when the instrument is due for re-calibration. This eliminates the need for manual tracking of calibration dates.

The VERI-CHEK® feature is a menu driven process by which the instrument's failure detectors are proven to be functioning properly, 'verifying' the functionality of the electrical safety tester and connected accessories.
