Hello
[img]http://img848.imageshack.us/img848/9938/20ksd.jpg[/img]
This is a photo of an open SD20KD are 10 transformers at source, in principle each can provide 2500w power before saturation of the core staff that is more technical know what I'm talking about and if you can explain to colleagues Croatian forum, I thank you.
At the source of the source are 18 capacitors are 1000mF x 250v.
The MOSFET of the source are IRFP1404, 206A at 25 ° C, 143A and 100 ° C.
The mosfest output are not mosfet, IGBT but are IRGP4072.
See you soon!

This power is in 12.6V to 20KW, we not tested other voltage.davor-ri wrote: 20kw @ 12-16-18-20V?
But we tested a 16KD in 16v and he provided 20.500 Wrms in burrp.
Look the result of output for 16KD in 16V...
Voltage:
Amps:
Very nice...
And as Ohm's Law is the same worldwide: 158.6 x 129.5 = 20538.7 WRMS
With these values we can find out in which he gave this power impedance:
Z = 158.6 / 129.5 = 1.22 ohms.
What do you think?
I'm pulling in English to talk to you, why in Brazil the official language is Portuguese ...
See you soon.

and starting and final impendance in this test was? (asuming this test was made on woofers)

The initial RE of SUB was 0.7 ohm and the final was 1.22 ohms.davor-ri wrote: and starting and final impendance in this test was? (asuming this test was made on woofers)
The above test was made with the subwoofer fron Fiat147 competition.
But the company tests are done with fixed resistors immersed in water with very 1ohm, the voltage is lower and the amps go up.
See you soon.
