    50Hz Hum Noise in power supply

    Hello I wanted to know how I could remove the 50Hz noise by hardware? The problem is the adapter comes without a GND pin and it gives an output of DC12V--4A. The 50Hz signal interferes with the measurement. RC low pass filter is one of the solutions but due to high current, it dissipates a lot...
