For example, on the train only 110V DC power supply, the power adapter connected to 110V DC, the power adapter can work?
If the power adapter is a bridge rectifier, it can be used; if the internal voltage is rectified, it is not available. DC input can not be times the pressure effect, the switching power supply on the high side of the required operating voltage.
Can work properly, its role in the exchange of 100V to 240V, the use of 110V DC problem no
Can not be used! Unless you buy a car power, it can convert DC to AC, 12V to 220V!
I'll answer you! Power adapter is a switching power supply, it is the first to rectify the AC rectifier, and then through the chip control power switch to a certain frequency of exchange for the exchange, and then through the transformer buck, and then rectified into a DC, the final output, I think the input DC should be no problem, you can use!
