    摘要: An input power measuring device includes a board with an edge connector, a first dual inline memory modules (DIMM) socket, a resistor, a differential amplifier circuit, a voltage dividing circuit, a display screen, and a controller. When the edge connector is inserted into a second DIMM socket of a motherboard and the motherboard is powered on, the resistor samples first current, and converts the first current into a first voltage. The differential amplifier circuit amplifiers the first current to a second current. The voltage dividing circuit divides the first voltage, and outputs a second voltage. The controller converts the second current into a third current, converts the second voltage into a third voltage, and calculates a power according to the third current and the third voltage.

    摘要: A sequence control circuit for power sources includes two switched circuits and a sequence control unit. Each of the switched circuits has a control node and is coupled between a power source and a load. The sequence control unit includes two output terminals coupled to the control nodes. The output terminals generate control signals to control the sequence of the circuits being turned on.
