The ISOMETERs® of the 107TD47 series monitor the insulation resistance of single and three-phase AC IT systems in medical locations. In addition, the IT system transformer is monitored for overload and overtemperature. In combination with the alarm indicator and test combination MK2430 they particularly comply with the requirements of DIN VDE 0100-710 (VDE 0100 Teil 710) and IEC 60364-7-710.
