[R-390] 400hz

[Bernie Nicholson]

Ok Rube you are generating 400 hz ac but the max power that you can get from a auto alternator is about is 520 watts devided by 3 will give 170 watts per phase  NOT enough !!! a arc58 system needs at least 3.5kva and a 618 system needs 2.5kva , even a big truck alternator will only deliver about 1kw , I have run these systems my making a regular psu and the only things that need 400 hz are the servo systems and you can get away with 20 watts for these but major surgery has to be resorted to in the radio  ,regards to everyone on the site
