ISOSCAN® EDS151

  • Automatic insulation fault location
  • Application control circuits
  • 6 measuring channels
  • Integrated measuring current transformers
  • Universal system concept

The insulation fault locator EDS151 in conjunction with the ISOMETER® isoMED427P, are designed for insulation fault location in unearthed power supplies (IT systems). The locating current pulse generated by the ISOMETER® isoMED427P 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.
