Abstract: A power transmission system is described. The power transmission system comprises a local power converter, a dedicated power transmission cable and a regulating unit. The power transmission system couples the local power converter to the KVM circuit of the remote KVM device via the dedicated power transmission cable and the regulating unit. The local power converter converts a first power signal into a second power signal. The dedicated power transmission cable has a first end and a second end. The remote regulating unit is able to regulate the second power signal to generate a third power signal. The first end of the dedicated power transmission cable is coupled to the power converter for receiving the second power signal from the local power converter. The second end of the dedicated power transmission cable is coupled to the remote regulating unit for supplying the regulated second power signal to the remote KVM device.
