  • Wire bound telecommunications device and a power supply circuit
    Patent number: 6728372
    Abstract: Known is a wire bound telecommunications device to be coupled to telecommunication lines comprising a transmission circuit coupled between the telecommunications lines, which transmission circuit comprises a power supply circuit for forming a supply voltage from a telecommunications line voltage, whereby the power supply circuit comprises sensing means for sensing a telecommunications line current and adjustment means for adjusting the supply voltage, a supply voltage terminal being coupled to the sensing means. In the known device, no optimal matching is obtained for the load line of the power supply to a DC-mask for line voltages as a function of a line current as prescribed for a given country. A more optimal matching is proposed.
