FRG-7 Current draw using an external 12V PSU

Hans Ostnell All Messages By This Member #303 Hi group, and thanks for having me! Anyone who can tell the current draw for a FRG-7, when using an external 12V PSU? I have a nice linear little PSU, but it's only capable of delivering 0,9 A continously. Thanks, Hans / LB6GG Sandnes, Norway

G. Marchal All Messages By This Member #306 Hello Hans, Don't worry, the needed current by the Frog is less than 500 mA. I don't use the internal PS of mine since a long time but an external 13.8 V one and I don't need anymore to put the lighting off to stop this rumble we all know.

Robert O'donnell All Messages By This Member #308 Well the manual says it draws 14VA at 120vac. So to translate that to 12vdc current draw would be:? So 14va*.7 ( .7 is the typ power factor of a std offline ps) = 9.8W of real power. So I = p/v, 9.8/ 12 = .82A? so your power supply should be fine. I have a frg-7, but never measured the DC current. Of course it will be less if you run it at 13.8V.? Hope this helps. Bob.? toggle quoted message Show quoted text On Fri, Nov 10, 2023 at 3:44 PM, Hans Ostnell <barentsdx@...> wrote: Hi Guy!
