IR420-D4 - Digital Ground Fault Monitor / Ground Detector Ungrounded (Floating) AC Systems
The A-ISOMETER® IR420-D4 monitors for ground faults in ungrounded AC systems from 0 to 300 V by measuring the system's insulation resistance.
The IR420-D4 is designed to provide predictive maintenence and detect ground faults in ungrounded systems before leakage current may even be present.
