Insulation monitoring device with fault location function
AM634 is a high-performance insulation monitoring device with fault location functionality. It is specially designed for medical IT systems to monitor the insulation status of single-phase or three-phase ungrounded networks. It also monitors the over-temperature and overheating of isolation transformers. The insulation monitoring device can be used in combination with the intelligent locating current transformer AM605-6 to quickly monitor and locate fault lines. It features a user-friendly display interface and can seamlessly communicate and connect with alarm panels and HMI centralized alarm systems.

Function Overview
■ Real-time monitoring and fault alarm functions for insulation resistance to ground of the monitored IT system, transformer load current, and transformer winding temperature
■ Can monitor in real time the wiring disconnection faults of the tested system, temperature sensor disconnection faults, and functional grounding wire disconnection faults, and provide alarm indication when faults occur
■ Can be used in conjunction with AM605-6 fault locating current transformers; when an insulation fault occurs on a line, alarm information can be quickly displayed and alarmed on the AM634 insulation monitoring device via communication
■ Each AM634 insulation monitoring host can be paired with 4 sets of AM605-6 fault locating current transformers, locating up to 24 lines, perfectly achieving comprehensive and rapid insulation fault location for each operating room
■ Local indication available: insulation level kC, transformer load rate, LED indication for insulation OK/insulation fault/current fault/temperature fault. Faults can be output via relay alarm, LED alarm warning, and uploaded via communication
■ Uses advanced fieldbus communication technology to communicate with external alarm and display instruments and upper computer management software
■ Can monitor the operating status of the IT system in real time
■ Has event recording function, capable of recording the time and type of alarm occurrence, facilitating operators to analyze system operation status and promptly eliminate faults
■ Can perform self-detection on communication wiring, transformer insulation measurement wiring, grounding connection, current transformer connection, temperature
■ Current transformer connection and other self-checks
■ Equipped with self-test and mute buttons
■ Programmable alarm buzzer
■ Immediate fault source identification
Standards Compliance
■ International standard products: IEC61557-8, IEC61557-9, IEC61558-1, IEC61326-2-4 (EMC Standard), IEC61010-1
■ Domestic standards: GB16895.24-2005/IEC 60364-7-710:2002 "Electrical installations of buildings Part 7-710: Requirements for special installations or locations Medical locations"
