Re: need help in Power Supply
- Hi, I'm new to this group but old and experienced with electronic
devices. Have you thought about a surge suppressor for your device?
Just a thought! c ya

- Hi, its always good to make one but i'm concern about your safety, on
your case if you are experiencing a huge amount of surge you dont
need to built one to replaced the other one the problem still there.I
would suggest to get one reliable UPS uninterruptible Power supply
this type of device has a voltage windows that can handle huge
amount of surge and sag.If out of your budget mind to get on surge
suppressor with circuit breaker.This i would like you to do if you
really want to built one first monitor your ac utility during day
and night time check how far the ac utility went beyond the nominal
voltage 110Vac, check your ac outlet where the fax machine
connected is it really properly grounded? if not have a elctrical
technicain look on it, reason why I want you to check the proper
grounding cause this in one reason why your psu on your fax keeps
busted. during that time.let me know if you needs more info on
voltage regulation.Electonics 101 advice Think first before you
jump...just be careful.safety first.
