Insulation monitoring device with integrated load and temperature monitoring and locating current injector for insulation fault location systems for medical IT systems Product description The ISOMETER® isoMED427P monitors the insulation resistance of unearthed AC circuits (medical “IT systems”). At the same time, the load current and temperature of the IT system transformer is monitored. In combination with EDS series insulation fault locators and the appropriate measuring current transformers, the isoMED427P is designed to set up the respective equipment for insulation fault location....

Alarm messages LEDs Operating elements isoMED427P “ON” Operation System fault* Insulation fault Overcurrent Overtemperature * Detailed alarm information on LCD Test function/connection monitoring A self test is carried out once supply voltage is fed and later at hourly intervals. During the self test, the internal device functions, the connections to PE (E/KE) and the connections to the current transformer are monitored for interrruption and short-circuit. In the event of a fault, the alarm relay K1 switches and the LEDs ON/AL1/AL2 flash. The respective error code appears on the LC display....
