The ISOMETER® of the IR425 series is designed to monitor the insulation resistance of unearthed AC/DC control circuits (IT systems) 0…300 V. DC components existing in AC/DC systems do not influence the operating characteristics. An external supply voltage allows de-energized systems to be monitored too.
