IRDH375B-435 Bender

Description

Product name：IRDH375B-435   Bender Power module

Product details:

The ISOMETER® of the IRDH375(B) 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 IRDH375(B) automatically adapts itself to

the existing system conditions.

In combination with a coupling device, the devices can also be used for higher voltages.

An external supply voltage allows de-energised systems to be monitored too.

When the insulation resistance between the system conductors and earth falls below the

set response value, the alarm relays switch and the alarm LEDs light up. Two separately

adjustable alarm relays allow to distinguish between prewarning and alarm. The measured

value is indicated on the LC display or an externally connectable measuring instrument.

In this way any changes, for example when circuits are connected to the system, can be

recognised easily. The fault message can be stored. The fault memory can be reset by

pressing the reset button. By pressing the test button, the function of the device as well

as the connections to system and earth can be tested. Pressing the Info button provides

additional information, such as the existing system leakage capacitance or device settings.

The function of the device and the earth connections are monitored. When a fault occurs, the

system fault relay switches and the alarm LED “system fault” lights up. The parameterisation

of the device can be carried out via the LC display or the function buttons integrated in the

front plate.
