sir it's very simple task! we can use same transformer for both 50/60 hz frequency. rest of ckt is just connection of voltage regulating ic. if you need ckt then i can provide it with detailed specifications in 1 day.

Product is readily available please let me know when you need this Contact me visuATadmalee dot com Visit our website www dot admalee dot com

I'm senior electronic engineer . I made many pcp designs for digital & analog signals as I work in power suply design using variable regulators to have voltage up to 48 volt and I also use microcontrtoller for many control circuit designs . Normally , I use proteus software in pcb design.

Hi, I am a PhD (doctorate) holder with faculty position and with 15 high ranked publications. To prove my claim, I can do small part of your job for free to check my expertise. Sincerely,

I have similar ones that is use for GSM communications in remote area's. What are the size constraints because your power requirement is 90W. which requires larger components. Otherwise i can have the schematic and list of components plus where to source them to you in 3 days
