dc power supply

  1. 12V-7A AC to DC Switching Power Supply [SMPS]

    The maximum power delivery of this power supply is 84W, which means it can handle 7A continuously at 12V output. The transformer can deliver higher currents, however, the educational purpose (hand winding of the transformer) and thermal stress on the switching controller were considered (the...
