ISOMETER® isoES425

For stationary energy storage systems according to VDE-AR-E 2510-2 (application)
Insulation monitoring device according to product standard IEC 61557-8
Preset response values according to the recommendation of VDE-AR-E 2510-2
Multifunctional LC display

The ISOMETER® isoES425 monitors the insulation resistance of unearthed AC, AC/DC and DC systems (IT systems) for energy storage devices up to AC/DC 400 V.

The DC-supplied components existing in AC/DC systems do not influence the operating characteristics. The isoES425 is used to monitor and indicate the connection to earth during network operation. When operated as an isolated system, the isoES425 takes over the monitoring of the isolated system (IT system).
