amplificador muito potente, apesar de eu estar usando uma fonte, muito inferior aos 38v 10 amperes, que o amplificador pede, irei comprar a fonte depois.

very powerful amplifier, even though I am using a power supply, much lower than the 38v 10 amps that the amplifier requires, I will buy the power supply later.

Q:
What power supply does this require?

What power supply does this require?
What power supply does this require?

A:

as stated - between 18 and 38 VDC. Notice - you only g1et the max power when using max voltage. The PSU must be able to deliver the same effect - I think at least 400W is needed. The TPC5532 chip allows up to 50VDC - so I guess it will accept variations ... I have my self use a un-regulated transformer-based PSU - 500W, 38VDC with some big capacitors - and that is working OK.
