Post output power calculation Reply with quote
so now we have a math question for all the math guys here on this forum.

i will like to dive the SD2941 Amp with one watt.
the pallet will do 175watts with 4 to 5 watts drive at 48 volts/7 Amps i also have a gain of 16db

again i will drive this unit with one watt with a 15 volt power supply @ 12 amps .

the transistor has an efficiency of 58 to 60%

can anyone provide a method to calculate the approximate output power from the SD2941

At this voltage and 1W drive you will probably get out zero watts.

This unit was designed for 48V and 3-5W drive and at 15V it won't
produce almost any power at all.

It will produce some power at 24-28V, but not much with 1W drive.

Its not expressible in a simple single formula.

But some years of experience tells you what to expect.
I expect close to zero watts output.
