POWER DISTRIBUTOR AND ON-BOARD NETWORK HAVING AT LEAST ONE POWER DISTRIBUTOR

The invention relates to a power distributor (2), in particular for an on-board network (4) of a motor vehicle (6), having an intermediate tap (16), two power outputs (10), and one each switching unit(28) for each power output (10), and having a switch (30) for need-based blocking of the associated power output (10). Each of said switching units (28) is designed in such a way that a blocking of the associated power output (10) takes place, if, in the event a voltage drop at the associated power output (10) and/or at the intermediate tap (16) below a first setpoint value, an error case is determined. The greater the corresponding voltage drop, the faster the blocking of the associated power output (10) takes place. 本发明涉及一种功率分配器(2)，尤其是用于机动车(6)的车载电网(4)的功率分配器，其具有中间抽头(16)、两个功率输出端(10)以及针对每个功率输出端(10)具有各一个切换单元(28)，切换单元具有用于根据需求来截止所从属的功率输出端(10)的开关(30)，其中，其中每个切换单元(28)构造成，使得当在所从属的功率输出端(10)上和/或在中间抽头(16)上的电压下降到第一给定值以下的情况下而获知故障时，使所从属的功率输出端(10)截止，其中，相应的电压下降越多，对所从属的功率输出端(10)的截止就越快实现。
