Choosing power supply, how to get the voltage and current ratings?
My DC adapter for a cordless mike has broken It' ratings are:
Input 230-240V ~ 50Hz 30mA Output 20V 250mA
Living in a country where it is not always possible to get the things we want, we often have to improvise.
I have an old laptop adapter - input 100-240V 50-60Hz Output 19V 1.58A (not mA!)
Can I use this to supply the power to the control box for my mike?
Thanks very much
