Abstract

The present disclosure relates to the field of low-voltage power distribution, and specifically discloses a low-voltage distribution switch and a power supply device, wherein the power distribution switch includes a switch module, a plurality of current detection modules and a metering module. A plurality of input ends of the switch module are adapted to be correspondingly connected to the multi-phase power supply line. The input ends of the plurality of current detection modules are correspondingly connected to the plurality of output ends of the switch module. The output ends of the plurality of current detection modules are adapted to be correspondingly connected to the multi-phase power supply line. Each of the current detection modules includes a plurality of current branches and a current detection unit. The distribution switch can improve the linearity and accuracy of the power metering function.
