IRDH275B-427 Insulation Monitoring Device
Manufacturer :- Bender
Description :- Bender
IRDH275B-427 Insulation Monitoring Device
Full Description :- The ISOMETER® of
the IRDH275 series is designed to monitor the insulation resistance of
unearthed main circuits (IT systems) AC, AC/DC 0…793 V resp. DC 0…650 V.
The AMPPlus measurement
method meets the particular requirements of modern power supplies which often
include rectifiers, converters, thyristor-controlled DC drives and directly
connected DC components.
In these systems often high leakage
capacitances against earth occur due to interference suppression measures.
The IRDH275
automatically adapts itself to the existing system conditions.
