Patent ID: 8354760

Claim:
Power supply equipment comprising: conversion circuitry for converting an input voltage to a high DC voltage and to first and second low DC voltages; a first power port operative to receive the high DC voltage at a first pin of the first power port and the first low DC voltage at a second pin of the first power port for output to an assembly; a second power port operative to receive the high DC voltage at a first pin of the second power port and the second low DC voltage at a second pin of the second power port for output to an assembly; at least one low power assembly which is detachably mateable between a corresponding low power electronic device and either of the first and second power ports; at least two high power assemblies, each of the high power assemblies being detachably mateable between corresponding high power electronic devices and either of the first and second power ports, each of the high power assemblies having a high power configuration which identifies the assembly as a high power assembly; and circuitry, responsive to the high power configuration of the high power assemblies, for preventing the high power electronic devices from receiving the high DC voltage when a high power assembly is mated to each of the first and second power ports, without putting the conversion circuitry in an overvoltage or overcurrent condition.
