If I have a device from the UK, and on its AC adapter, it says that on 'sec' (presumably referring to the secondary winding of the transformer), the output is as follows: 12 V 1500 mA 18VA My question is as follows...if I don't have an adapter for the UK style plug at this moment (or a transformer to provide the proper 230 V AC), and I don't want to try and get a North American-style AC adapter from the company that manufactures the device just yet, then would the following be a possibility? If I manage to dig up an AC adapter that has the same output on the DC side as this one, is it safe to just USE it with the device? My reasoning is that if the voltage is the same, presumably all of the ICs etc will be happy...they'll be getting the correct Vcc's or Vss's or whatever the hell they need. As for the current, I am assuming that the 1500 mA is an upper limit on the current that CAN be supplied by the AC adapter based on the power that is going in. That would suggest to me that as long as the output current on my scavenged AC adapter is less than or equal to 1500 mA, then I'll be ok. The device may not quite be getting enough power to make it work, but it will be safe. On the other hand, I am assuming that if the current limit on my scavenged AC adapter is higher than 1500 mA, then it will be unsafe, because it will then be *possible* for the device to draw more current that it would be able to if connected using the manufacturer's AC adapter. But am I wrong? Have I got things the other way around? Is the 1500 mA NOT an upper limit after all?
