Abstract:
1. A power supply with arc flash protection mechanism, comprising: a first power connector including a plurality of power terminals and a first detecting terminal, wherein said plural power terminals are configured to couple with a plurality of power terminals of a second power connector, and said first detecting terminal is configured to couple with a second detecting terminal of said second power connector and provide a detecting signal indicative of whether said second power connector is being disconnected with said first power connector; a power conversion circuit electrically coupled to said power terminals of said first power connector for receiving an input voltage and converting said input power into an output voltage; a control unit electrically coupled to said power conversion circuit for controlling the operation of said power conversion circuit; and a connection status detection circuit electrically coupled to said control unit and said first detecting terminal of said first power connector for generating a power connection status signal to said control unit according to said detecting signal; wherein when said first detecting terminal of said first power connector is disconnected with said second detecting terminal of said second power connector, said power connection status signal is under disable status and said control unit controls said power conversion circuit not to generate or output said output voltage to a load according to said power connection status signal.
