The Chroma 19050 series Hipot Tester is comprised of two models. The 19052 is equipped for AC/DC/IR Hipot testing and insulation resistance (IR) measurements. The 19053 combines both AC and DC Hipot tests and IR measurements with 8HV scan channel capabilities. With both models, front panel operation, digital display, and user-friendly controls allow test parameters and limits to be easily set.
The OSC function is used to check whether the connection is open circuit between instrument and DUT or breakdown inside DUT before testing the electrical safety. These testers have a ground continuity check feature to determine the resistance, that is between the ground blade of power cord and any exposed metal on the product, is less than 1Ω. GFI is required by the National Electrical Code in wet locations. Such devices automatically interrupt power when a ground current > 0.5 mA for more than a few milliseconds to protect users. In DC hipot and IR test the device under test is discharged back through the HV transformer. This technique results in a rapid and safe discharge.
