EDS490 Series

Ground fault location module for ungrounded AC/DC systems


Compatible with IRDH575

The EDS490 ground fault location module, in combination with the IRDH575 ground fault detector, locates branch faults in ungrounded AC/DC systems. Up to 12 separate branches may be monitored by one EDS490 device. Up to 90 EDS devices may be connected together, for a total of 1080 branches simultaneously monitored. The EDS490 works on both AC and DC systems, including systems with variable frequency drives (VFDs). Devices are interconnected via RS-485 to automate the process of locating faults. An LCD display shows which branch has the ground fault after it has been located. One common DPDT contact is built into the EDS490, along with twelve separate SPST contacts, one for each channel.

The EDS490 is used with the IRDH575 ground detector and is designed for large power distribution networks. It features a common DPDT contact output and twelve SPST contact outputs, one for each channel.
