This site

http://www.datadart.com/al/sanyo/sanyodata.htm

contains the data sheet. It's also a good idea to check the data sheet for STK4048XI as it is contains a bit more information and as they are quite similar.

Did you even bother to look in the data sheet?

Ohms law:

U = R*I => I = 66 V/8 Ohm = 8,25 A

16,5 A is needed for a 4 Ohm load. But these are peak currents so 8,25 A/(sqrt(2)) = 5,8 A continous and the double for 4 Ohms.

And add some to count for the losses...

THANKS U!!!

I build a amp With 2 STK4050V IN 8 Ohm


soo i need a power 66V ~ 16.5A in a 8 Ohm (for two STK)

or 66V ~ 30A in a 4 Ohm ( for two STK)...

yes??

if .............

66V ~ 8Ohm (IN STK4050V) = 200W R.M.S

soo....

66V ~ 4Ohm (in stk4050V) = W ????

U=R*I
P=U*I

With these formulas you can do most of the calculations you need. But remember that Up-p = (sqrt(2))*Urms and the same for current.

This means that the power doubles when you take half the load.

The transformer you need will be quite large (>1000 VA).
