• Spoorwegen
  • Universeel inzetbaar

De ISOMETER® isoRW685W-D is een isolatiebewakingsapparaat volgens IEC 61557-8 voor IT-systemen voor spoorwegtoepassingen en speciaal getest volgens DIN EN 50155. Dit product is universeel inzetbaar in AC-, 3(N)AC-, AC/DC- en DC-systemen. In AC-systemen kunnen ook omvangrijke installatieonderdelen met gelijkstroomvoeding aanwezig zijn (bijv. statische omvormers, gelijkrichters, geregelde aandrijvingen).
