The HypotMAX series offers 500 VA testing in 3-in-1 and 4-in-1 electrical safety compliance analyzers. The 770 is a 3-in-1 model that provides 500 VA Hipot, DC Hipot, and Insulation Resistance testing. The 7704 is a 4-in-1 model that adds 30 Amp ground bond testing to the functionality of the 7700. The combination of 500 VA Hipot testing and DC Hipot Testing, Insulation Resistance and Ground Bond testing allows manufacturers to meet a variety of tests requirements with a single instrument. These testers are easy to use and designed with advanced features such as our patented SmartGFI® safety circuit and our patented CHARGE-LO and RAMP-HI systems. With both IEEE-488 (GPIB) and RS-232 Interfaces these testers are well suited for both bench top and automated applications.
