HPRS-HIPOT-LOAD (Fluke 5320A-load hipot replacement) – Hipot current calibration load resistors

The IET Labs HPRS-Hipot-load is an excellent replacement for the Fluke 5320A-load hipot current calibration load resistors.

IET HPRS Hipot Load

The IET Labs high power resistive load can be used with the Fluke 5320A multifunction electrical tester, calibrator or standalone.
It provides a high power and high voltage load to various hipot tester to create the leakage current needed to calibrate various manufactures hipot testers.
