Product description:

Using the low-frequency pulse square wave injection method can reliably and accurately monitor the insulation resistance of AC, DC, and AC-DC hybrid IT systems (ungrounded systems) to ground. Due to various applications, system types, operating conditions, application of variable speed drives, high system leakage capacitances, etc., the measurement technology must be able to meet different requirements in order to ensure optimized response times and relative uncertainties. Different measurement conditions, which can be selected from the settings menu, allow optimal adaptation to the specific application measurement technique.
