The present disclosure relates to a power distribution unit (PDU) having at least one power receptacle for enabling attachment of an AC power cord of an external device thereto. A branch receptacle controller (BRC) has at least one bistable relay and is associated with the one power receptacle for supplying AC power thereto from an AC power source. The BRC monitors a parameter of a line voltage and uses it to detect when AC power is lost, and then toggles the bistable relay, if the relay is in a closed position, to an open position. A rack power distribution unit controller (RPDUC) monitors the bistable relay and commands the BRC to close the bistable relay after AC power is restored. 本申请涉及管理双稳态继电器以减小浪涌电流的智能电源板。具体涉及一种配电单元(PDU)，其具有至少一个电力插座，用于使外部设备的AC电力线能够附接至至少一个电力插座。分支插座控制器(BRC)具有至少一个双稳态继电器，并且与一个电力插座相关联，用于从AC电源向一个电力插座提供AC电力。BRC监测线路电压的参数，使用该参数来检测何时失去AC电力，然后如果继电器处于闭合位置，则将双稳态继电器切换到断开位置。机架配电单元控制器(RPDUC)监测双稳态继电器，并且在AC电力被恢复之后命令BRC闭合双稳态继电器。
