Thanks for the help Geoff. I have a basic and a general question at the moment. I come across power requirements stated as VA, Amp., or Watts on the specs sheets. How can I standardized them on, say a Watts scale, considering the line voltage in UAE is 230v (+/- 5%) AC 50Hz 1 Phase. How about equipment running on DC through a line voltage adapter? Sorry, this appears to be a basic elementary stuff, but slightly lost here. lol.
