Re: redfox ez3540-i85iw bios
still i suspect to be a bios, since voltages are present, the pch and cpu is getting warm and hot(not so hot, just anormal temp when board is on) indicating that they are working when turn on.

Re: identify torroidal transformer amperage
its dual secondary, there are 3 wires is sencondary, blue-black-blue(28-0-28)
my transformer weighs 1.25kg, its outer diameter is 94mm, height 39mm, inner diameter is 45mm. its rough measurement

Re: identify torroidal transformer amperage
hmm so 230V/28V = 8V
and 8V/1.5A = 5A, so my transformer output current is upto 5A?
230V primary, 28V-0-28V secondary

Re: identify torroidal transformer amperage
hi sam, i only have the transformer now, yeah i connected a bridge rectifier without caps and load, i run it like that for almost an hoir, the temps of the transformer felt like normal, not hot , jus normal temp i have no thermal scanner to exactly do temp meas, one thing i did not do is to put a load on it, anyway can you guess the amps based on its marking?
