一种机柜电源设备，用以对装设于机柜内的若干台服务器供电，该机柜电源设备包括PDU以及分别对应一服务器设置的若干个PSU，所述PDU包括配线板、插接板以及底板，所述配线板连接至插接板，用以将从外界接入的三相交流电经分配成若干路单相交流电，所述若干PSU并联于插接板与底板之间，且每一PSU从所述插接板上获取一路单相交流电，并将该交流电转换成服务器所需的电压后发送至底板，该底板将若干PSU发送的电压重新分配给各台服务器。

The present invention provides a power source equipment for cabinet for server. The equipment includes a PDU and a plural of PSUs. Each PSU is for supplying power to a server. The PDU includes a wiring board, a connecting board, and a baseboard. The wiring board electrically connects to the connecting board, and is for converting the three-phases AC to three one-phase AC. The PSUs are electrically parallel connect between the connecting board and the baseboard. Each PSU gets a one-phase AC from the connecting board, and converts the AC source to DC source, and then transmits the DC source to the baseboard. Thereafter, the baseboard distributes the DC sources from each PSUs to each server.
