Drawings indicate DC-DC switching power supply can be replaced with AC-DC switching power a?
Generally, as long as the output voltage is equal, the current is enough to be interchangeable.
DC input switching power supply and AC input switching power supply is not interchangeable. But if you have the knowledge of this circuit, after the transformation of the circuit can be interchangeable. Principle: AC input switching power supply, the AC input rectified filter voltage and DC input switching power supply DC input voltage of the same.
General low-power switching power supply input can be as low as 85VAC. Equivalent to 110DC, in the allowable voltage range should be possible.
Can be common, AC input to rectify to work, but the input voltage is DC = 1.4AC Caixing
