A-ISOMETER® isoMED427P

The A-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.

Insulation monitoring device with integrated load and temperature monitoring and locating current injector for insulation fault location systems for medical IT systems in accordance with IEC 60364-7-710, IEC 61557-8, IEC 61557-9 and DIN VDE 0100-710

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

EDS151

The insulation fault locator EDS151 in conjunction with the A-ISOMETER® iso-MED427P, the automatic transfer switching device ATICS or the locating current injector PGH474, are designed for insulation fault location in unearthed power supplies (IT systems). The locating current pulse generated by the iso-MED427P, ATICS or PGH are detected using the integrated measuring current transformers and evaluated by the insulation fault locators. The integration of six measuring current transformers in an EDS151 permits all current-carrying conductors of an outgoing line to be routed through. The response time for an alarm message inclusively indication on the respective display device is max. 8 s (e.g. MK2430).

A total of 88 EDS151 devices can be connected via an RS-485 interface (BMS protocol). Hence, up to 528 circuits can be monitored. Activities on the BMS bus are indicated by an alarm LED.
