IRDH275-435 Bender

Description

Product name：IRDH275-435 Bender Power module
Product details:

The ISOMETER® monitors the insulation resistance RF of unearthed AC/DC main circuits (IT systems) with
nominal system voltages of 3(N)AC, AC/DC 0 … 690 V or DC 0 …1000 V.
DC components existing in 3(N)AC, AC/DC systems do not influence the operating characteristics when a
minimum load current of DC 10 mA flows. The separate supply voltage Us
allows de-energised systems to be
monitored as well.
The ISOMETER® is always used in conjunction with the coupling device AGH420.
In order to meet the requirements of the applicable standards, customised parameter settings must be made
on the equipment in order to adapt it to local equipment and operating conditions. Please heed the limits of
the range of application indicated in the technical data.

• Monitoring for unearthed AC and DC systems with galvanically connected rectifiers or frequency converters
• Measuring the nominal system voltage Un (true RMS) with undervoltage/overvoltage detection
• Selectable start-up delay, response delay and delay on release
• Measuring the residual voltages of the supply system to earth (L1/+, L2/– to PE)
• Automatic adaptation to the system leakage capacitance Ce up to 1000 μF
• Automatic device self test with connection monitoring
• Two separately adjustable response value ranges from 1…500 kΩ (alarm 1, alarm 2)
• Alarms output via LEDs (‘AL1’, ‘AL2’), a display, and alarm relays (‘K1’, ‘K2’)
• Selectable N/C or N/O relay operation
• Measured value display via multi-functional LC display
• Fault memory can be activated
• Password protection against unauthorised changing of parameters
• RS-485 (galvanically isolated) including the following protocols:
– BMS (Bender measuring device interface) for the data exchange with other Bender devices
– Modbus RTU
– IsoData (for continuous data output)
