VIGILOHM изолационно мониторинг устройство IM9 110-415VCA

Vigilohm IM9 is an insulation monitoring device (IMD) permanently monitoring ungrounded/IT earthing systems as per IEC 60364 requirements. According to standards, it is recommanded to equip your systems with Insulation Monitoring Devices (IMD). It monitors LV networks up to 600VAC or 480VAC when connected to neutral or to line respectively. It mesures the system insulation resistance by injecting a DC current between the network and ground. IM9 is versatile, adapting to networks resistance betwen 1k and 500 kOhm with an accuracy around 15% at 10 kOhm and 1 µF. To meet your applications, the device insulation alarm thresholds can be set between 1k and 250 kOhm. Once the alarm threshold is breached, it triggers an alarm that is relayed by 1 standard or fail-safe dry contact or by the local front face LED. It contributes to minimizing operational losses, downtimes, people safety risks and installations damages. This IMD benefits installations where continuity of power supply is critical and where unexpected interruptions must be kept to a minimum. The device can be supplied by a 110VAC to 415VAC or a 125VDC to 250VDC source, with 15% tolerance, plus or minus. It monitors purely AC systems of short length, with very limited loads and disturbance. The relay can be manually tested with a self-test button to ensure that the monitoring of the ungrounded system remains permanent. It has been designed according to EN/IEC 61557-8 product standard and has Marine certification. It can be DIN rail or flush-mounted to meet your installation. The HMI design makes it easy for the user to do device configurations, manual test, or to get informed about the device and network status. Vigilohm benefits from over 50 years' experience of insulation monitoring devices design by Schneider Electric. It is installed all over the world in industrial, marine, transportation, power generation or infrastructure sites.
