We have low voltage (24VDC) cubicles and consoles fed off a common low voltage bus. I am trying to find a way to detect a "reverse power" situation where someone might have accidentally connected 24VDC on the load side. We thought about using a Hall Effect sensor to light up an LED but our current (25mA to a few amps) is too small to produce magnetic field large enough to be sensed by Hall Effect sensors.
Any idea how to detect reverse power on low voltage/current DC buses?
thanks
