IRDH275BM-7
with AGH675S series Device combination for insulation monitoring in ungrounded medium AC, AC/DC and DC systems (IT systems) The device combination ISOMETER® IRDH275BM-7 and the coupling device AGH675S-7 or the coupling devices AGH675S-7MV15 is designed to monitor the insulation resistance of unearthed medium voltage systems (IT systems). It is suitable for universal use in 3AC, combined AC/DC and DC systems. AC systems may include extensive DC-supplied loads. 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. Taking the system leakage capacitances into account, the IRDH275BM-7 automatically adapts itself to the existing system conditions in order to optimise the measuring time. |

iso685-…-P Insulation monitoring device with integrated locating current injector for IT AC systems with galvanically connected rectifiers or converters and for IT DC systems The ISOMETER® is an insulation monitoring device for IT systems in accordance with IEC 61557-8 and IEC 61557-9. It is universally applicable in AC, 3(N)AC, AC/DC and DC systems. AC systems may include extensive DC-supplied loads (such as rectifiers, inverters, variablespeed drives). In combination with the insulation fault locators of the EDS44x series or the appropriate measuring current transformers, an insulation fault location system can be set up with the iso685-D-P. Device variants iso685-D-P With high-resolution LCD display and operating controls for direct operation of the device functions. It cannot be combined with an FP200. iso685-S-P Without LCD display and can only be used in combination with an FP200. The iso685-S-P is thereby operated indirectly via the FP200. Option "W" Used for extreme climatic and mechanical conditions. |

IRDH575 (panel mounting) Insulation monitoring device for ungrounded AC, DC and AC/DC systems (IT systems) 20…575 VDC/340…760 VAC with integrated test generator and controller for EDS insulation fault location systems (html) The ISOMETER® of the IRDH575 series monitors the insulation resistance of unearthed power supplies (IT systems). It is suitable for universal use in 3(N)AC, AC/DC and DC systems. AC systems may include extensive DC-supplied loads, such as converters or thyristor-controlled DC drives. The IRDH575 in combination with EDS4… series insulation fault locators and the appropriate measuring current transformers is designed to set up the respective equipment for insulation fault location. |
