Can I Operate my AC-DC Power Supply with a DC Input?
...The answer is yes, sometimes.
Many standard AC-DC switched mode power supplies (most of TDK-Lambda's products) specify a high voltage DC input range in addition to the more common AC input range of 90-264VAC. We receive many questions about how and where to connect the DC input to an AC-DC supply that is specified to operate off of DC as well as an AC inputs.
