Contains a positive and negative bus-bar and provides a connection for 4 individual DC equipment circuits loads or DC groups. It has a space for individual DC fuses per DC group. There is an optional feature of an LED for each fuse to indicate if fuse is blown. If you wish to use the fuse indication LEDs on the Lynx Distributor it also requires a connection to a Lynx Shunt. The Lynx Shunt contains the necessary wide input 8 to 70VDC power supply to output the required 5V 45V-55V power requirement of the Lynx Distributor circuit board. RJ10 fly leads are used to connect the Lynx Shunt to the Distributor. This RJ10 cable is supplied with the Distributor in the box. There are two ports on the Lynx Shunt and it is possible to use either. When all is OK only the central LED is green; when a fuse has blown or is missing the central and blow fuse circuit LEDs turn red. If you are not using all connection points in your DC distribution it may be necessary to fit dummy fuses to extinguish the red LEDs.
