MANAGING DC POWER

Examples are disclosed that relate to power supply devices and methods for managing DC power. In one example, a method comprises: providing DC power at a first voltage until determining that a standby time period has elapsed; determining that a load is connected to the power supply device; and based on determining that the standby time period has elapsed, entering a restricted power mode, wherein the restricted power mode comprises either: deactivating the DC power, or (1) providing the DC power at a second voltage until determining that a load detection time period has elapsed, (2) deactivating the DC power after determining that the load detection time period has elapsed, and (3) repeating (1) and (2) until determining that the load is no longer connected to the power supply device. 公开了涉及用于管理DC功率的电源设备和方法的示例。在一个示例中，一种方法包括：以第一电压提供DC功率，直至确定待机时间段已流逝；确定负载被连接到电源设备；以及基于确定待机时间段已流逝，进入受约束功率模式，其中该受约束功率模式包括要么：停用DC功率，要么(1)以第二电压提供DC功率直至确定负载检测时间段已流逝，(2)在确定负载检测时间段已流逝之后停用DC功率，以及(3)重复(1)和(2)直至确定负载不再连接到电源设备。
