Abstract
A multiple communications port unit for coupling plural peripheral devices to a computer. The multiple communications port unit includes a network port for being coupled to a supervisory computer, communications ports for being coupled to the peripheral devices, and a power supply unit suitable for using the substation battery at an electric distribution substation for input power. The power supply unit includes redundant power supplies, an input conditioning circuit, and a sensing and annunciation circuit for providing a warning of a power supply malfunction.
Claims52
A multiple communications port unit, comprising:
- plural communications ports adapted to communicate with peripheral devices;
- a network port adapted to communicate with a computer over a network link;
- and
- a power supply unit coupled to said communications ports and to said network port and having an input voltage of greater than or equal to 88 Vdc, said power supply unit comprising two power supplies configured to operate in a redundant manner, each of said power supplies comprising a flyback topology unit configured to provide a substantially constant dc voltage to said power supplies when the power supply unit has said input voltage.
A multiple communications port unit, comprising:
- plural communications ports adapted to be coupled to intelligent electronic devices;
- a fiber optic network port adapted to communicate with a computer over a network link;
- a power supply unit coupled to said communications ports and to said network port and having an input voltage of greater than or equal to 88 Vdc, said power supply unit comprising two power supplies configured to operate in a redundant manner, each of said power supplies comprising a flyback topology unit configured to provide a substantially constant dc voltage to said power supplies when the power supply unit has said input voltage.
A computer architecture comprising:
- a computer;
- plural peripheral devices;
- and
- a multiple port communications unit having plural communications ports coupled to said peripheral devices, a network port coupled to said computer over a network link, and a power supply unit coupled to said communications ports and to said network port and having an input voltage of greater than or equal to 88 Vdc, said power supply unit comprising two power supplies configured to operate in a redundant manner, each of said power supplies comprising a flyback topology unit configured to provide a substantially constant dc voltage to said power supplies when the power supply unit has said input voltage.
A multiple communications port unit, comprising:
- communication means for communicating with peripheral devices;
- network means for communicating with a computer;
- power supply means for providing power to said communication means and said network means, said power supply means having an input voltage of greater than or equal to 88 Vdc, said power supply means comprising two power supplies configured to operate in a redundant manner, each of said power supplies comprising a flyback topology unit configured to provide a substantially constant dc voltage to said power supplies when the power supply means has said input voltage.
