250 V, 10 - 200 kΩ | A-ISOMETER® IR125Y-4 series BENDER

  • insulation monitoring device 250 V, 10 - 200 kΩ | A-ISOMETER® IR125Y-4 series BENDER
The A-ISOMETERs® of the IR125Y series are designed to monitor the insulation resistance of unearthed AC and DC control circuits (IT systems). External supply voltage is not required.
In contrast to insulation monitoring device which evaluate the shift voltage for insulation fault detection, this series uses the active AMP measuring principle. This creates the possibility to detect and indicate both symmetrical and asymmetrical insulation faults.
