Schneider Fault Locator Vigilohm_ VIGILOHM 12 CHANNEL FAULT LOCATOR WITH MODBUS HOSPITAL - 110-230VAC - 125/250VDC_ [IMDIFL12H]

This device belongs to the Vigilohm range designed to monitor ungrounded/IT electrical networks at feeder level, in accordance to installation and products standards This insulation fault location is only possible when it is associated to IM400 20-H. This device is dedicated to monitoring 12 feeders, AC, DC and ACDC, up to 1000V with the voltage adaptor, IFL12VA1T. It mesures the insulation resistance and leakage capacitance per feeder. Configuration is set from the front of the device, through the HMI screen, or from the communication port. Main settings are related to alarm thresholds, channel naming, toroid type (Vigilohm type or other compatible ones), filtering time. Per feeder, it displays insulation resistance from 100 ohms to 250 kilohms and leakage capacitance from 1 to 15 microfarad. Auto-test starts automatically every 5 hours, and on demand. In case the insulation resistance drops below the set threshold, an alarm is triggered thru the IFL output relay, HMI and communication port. Once no fault is monitored, the alarm is cleared, the alarm relay is back to normal. The device can be supplied by a 110VAC to 440VAC source or a 110VDC to 440VDC, all with a tolérence of plus or minus 15%._ [IMDIFL12H]
