Product Details：

IRDH275B-435 BENDER Insulated monitor

Product Dimensions：

nsulation monitoring device with load current and temperature monitoring for IT systems in medical locations in accordance with DIN VDE 0100-710 and IEC 60364-7-710

If one of the measured values exceeds the limiting value (insulation resistance, load current, temperature), an alarm is initiated. The alarm relay switches, the ALARM LED lights up and a message appears on the LC display. This alarm message is transferred to remote MK2430 alarm indicator and test combinations installed in the medical location via two-wire interface so that the technical or medical staff is informed immediately. The measuring leads to the system and PE, to the current transformer and to the temperature sensor are monitored continuously. If one of these measuring leads is interrupted or short- circuited, a message will appear. The function of the device can be checked by pressing

The insulation resistance of operating theatre lamps often is monitored by another insulation monitoring device that activates a relay contact in case of alarm (voltage-free NO contact). The alarm message of this contact is recorded by the 107TD47 and transferred via the BMS (Bender Measuring Device Interface) bus to other Bender devices such as a remote alarm indicator and test combination. In order to detect the load current in three-phase systems, an CMS460-D4-2 load current monitor is required which in combination with the STW2 current transformers measures the current of the phase conductors. The highest value of the load current is evaluated by the electronics and is made available at the input k/l of the 107TD47.
