Electromechanical relays (Electromechanical Relay, EMR) with relatively little impact on changes.

Because, although the solid state relay has the characteristics of low energy consumption, it is very sensitive to the temperature change generated when the load is large current, so that the first switch unit 20 cannot stably withstand the high power output, therefore, the second switch unit 22 electromechanical The collocation of the relay can maintain the maximum amount of current that the multi-port power supply monitoring device of the present invention should have, so that each switch module 2 can switch back and forth between each first switch unit 20 and each second switch unit 22 to conduct, so that The load can operate among high power mode, low energy consumption mode and off mode, achieving the effect of switching between high efficiency and energy saving.

In this embodiment, the low energy consumption mode is defined as the conduction of the first switch unit 20 and the conduction of the second switch unit 22; when the conduction of the second switch unit 22 and the conduction of the first switch unit 20 is defined as The high power mode, and when the first switch unit 20 and the second switch unit 22 are not turned on at the same time, it is the off mode.
