ISOSCAN® EDS460-DG

ISOSCAN® EDS460-DG

El módulo de localización de falla a tierra en combinación con el  detector de falla a tierra IRDH575 o de un aparato de prueba de fallos de aislamiento PGH, localiza fallas  en derivados  de sistemas no aterrizados de CA /CD. Por cada EDS460DG se pueden monitorear hasta 12 circuitos derivados. Se pueden conectar a  través de un interfaz RS-485 (Protocolo BMS), hasta un máximo de 90 aparatos de evaluación EDS y de este modo se pueden vigilar hasta 1080 salidas.  El EDS460 trabaja en ambos sistemas de CA y CD, incluyendo sistemas con variadores de frecuencia. Una pantalla LCD muestra cual derivado presenta la falla a tierra tan pronto como la falla es localizada.
