The Comm/net Systems FDN is an advanced fuse panel that provides robust, high-density DC power distribution for medium-current applications where fuses are preferred. The FDN is available in single- and dual-input (A/B redundant) versions, and can be used as standalone distribution in equipment racks or can be integrated into Comm/net Systems’ BDFBs. Rated at 600 amps per bus in only 3RU, the FDN provides fuse protection for up to six loads (3A/3B in redundant configuration). The fuse sockets support standard TPL-B telecommunications fuses available from 70 amps to 250 amps. The FDN monitors individual load current and features programmable de-rate thresholds to provide ample warning before any fuse is overloaded.
The FDN provides real-time panel status on the touchscreen display including input voltage per bus, total current per bus, current per load, temperature, as well as fuse fail and other alarms. The bright LED backlight changes color under warning and alarm conditions, allowing the operator to quickly see the status of the panel from a distance. A standard dry-contact summary alarm output is also provided.
The optional Ethernet module allows the panel to be remotely monitored over a network. Status data is available via web (HTTP), SNMP, and email notifications.
