The invention relates to the domain of electrical engineering, paticularly to a power supply system of computer network. The offered power system of telecommunication devices is characterized in that DC supply nodes of individual devices are connected to the radial loop. Zener diode shunts each input node, herewith one node’s anode of the Zener diode is connected to the next node’s cathode of the Zener diode. Open part of the radial loop between the cathode of the first Zener diode and the anode of the last Zener diode is connected to a common current source. The invention can be used to create branchy networks of any topology with great length. Also it can be applied to existing traditional computer networks without changing the topology or using additional wires to provide power to telecommunication devices. |
