Calculation

[aguantesoda]

Hi! I want do to know the power of my amplifier, knowing that the tension is of 25v+25v and RL is 8 ohms.?


hola, quería saber como hago para calcular la potencia de mi amplificador, sabiendo que la tensión es de 25v+25v. y la carga es de 8 ohms?

It is for this amplifier:

Hi,

If +/-25V is loaded voltage, then the output power is about 30W RMS on 8 ohm.
If 25V is the idle voltage, then it produces about 20W RMS.

Regards,

On the margin for that power I would choose something more elegant, maybe an integrated power amplifier.

At "integrated power amplifier" I mean chip amplifier.

Es para este amplificador:

For +/-22 Volt peak Max Output ( -3V drop for transistors, and also power supply transformer drop )
FORMULA: P (WATT rms) = ( UxU ) / ( 2xRL )
Watt RMS = 22x22 / 2x8
Watt RMS = 484 / 16

Resultade: 30.25 Watt RMS into 8 Ohm
Answer you get MAX ~30 Watt power / 8 Ohm

(And maybe 40-50 Watt into 4 Ohm speakers )

As I wrote too.

Very good! thanks
