heid587 Posted March 4, 2012 Share Posted March 4, 2012 (edited) anyone know of a guide or know themselves of how to use a pc power supply on a panasonic fz-1 3do. i am asking as i have purchased this system with a fried transformer and instead of sourcing another transformer. difficult for me as the old one is a 110v unit and i'm in aus and would prefer to use a 220v-240v power supply i had thought about sourcing a uk or eu transformer but its very hard to find just a transformer without taking the risk on buyin a dead unit and then the chances that the dead ones problem aint the same and then the price of postage on top... anyway i would really appreciate some help or any ideas at all? here are some pics of the units supply with voltages written on there http://i165.photobuc...6414_30edit.jpg http://i165.photobuc...6411_30edit.jpg http://i165.photobuc...6410_30edit.jpg Edited March 4, 2012 by heid587 Quote Link to comment Share on other sites More sharing options...
SEgamer Posted March 5, 2012 Share Posted March 5, 2012 (edited) Just to make sure, you did check to see if the primary windings and secondary windings on the transformer are still intact with a continuity meter? Sometimes I automatically assume a component is faulty only to realise it is something else later. Looking at the datasheet for the one that ouputs 9V (assuming I read the number right), it can take between 10V to 30V for its input voltage. I believe it is essentially a voltage regulator that can use a much wider range of input voltages, unlike the 7805 regulators that were used in just about everything. datasheet: http://html.alldatas...2/SI-3090C.html Not sure what the other one is, but it probably works the same and regulates the voltage at 5V. So any transformer with a secondary voltage of ~14V to ~25V (maybe less) should be on the safe side. They probably used 14.5 VAC (which is rectified to DC) to count for the load when it is connected to the circuit, which would bring it down to maybe around 11-12V which is ideal. If you can't find one, then you should be able to use a transformer with a higher voltage output. That is, unless that AC voltage goes somewhere else...
