Product Details
Product descriptionThe ISOMETER® of the IRDH375(B) series is designed to monitor the insulation resistance ofunearthed main circuits (IT systems) AC, AC/DC 0…793 V resp. DC 0…650 V. The AMPPlusmeasurement method meets the particular requirements of modern power supplies whichoften include rectifiers, converters, thyristor-controlled DC drives and directly connectedDC components. In these systems often high leakage capacitances against earth occurdue to interference suppression measures. The IRDH375(B) automatically adapts itself tothe 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.ApplicationFunctionWhen the insulation resistance between the system conductors and earth falls below theset response value, the alarm relays switch and the alarm LEDs light up. Two separatelyadjustable alarm relays allow to distinguish between prewarning and alarm. The measuredvalue 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 berecognised easily. The fault message can be stored. The fault memory can be reset bypressing the reset button. By pressing the test button, the function of the device as wellas the connections to system and earth can be tested. Pressing the Info button providesadditional 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, thesystem fault relay switches and the alarm LED “system fault” lights up. The parameterisationof the device can be carried out via the LC display or the function buttons integrated in thefront plate.Device version IRDH375BDevice version IRDH375B includes the following additional functions:• History memory with real-time clock to store all alarm messages with date and time stamp• Electrically isolated RS-485 interface (BMS protocol) for communication with otherBender devices• Isometer disconnecting relays for the operation of several ISOMETER®s in coupled IT systems• Current output 0(4)…20 mAUse in coupled IT systemsOnly one ISOMETER® may be active when several IT systems are coupled. Isometer disconnecting relays and the control inputs F1/F2 integrated in version IRDH275B guaranteethat only one ISOMETER® is active at any one time.Measurement method The IRDH375(B) uses the patented AMPPlus measurement method.This measurement method allows concise monitoring of modernpower supply systems, also in case of extensive, directly connected DC components andhigh system leakage capacitances.
