Description:
This is pure power amplifier board, the sensitivity of the input signal of 1.5Vrms, if your input signal voltage can't reach this value, recommend add preamp. Mono channel, for 2.0 channel need bid two. The rated output power: 500W ( DC +/- 65V power supply, 4 ohm load, distortion 10%) Efficiency: ≥90% SNR: 90dB color: blue The total harmonic distortion: 380W (+ /- 65 power 4 ohm speaker, distortion Less than 0.1%) 280W (+ /- 65 power 8 ohm speaker, distortion Less than 0.1%) Frequency range: 20Hz-20KHz Speaker: 4-8ohm Voltage Magnification: 36 times Input sensitivity 1.5V (RMS) 0. Output short circuit protection: Yes That output DC bias protection speaker protection: Yes Over-temperature protection: Yes, radiator FET temperature higher than 100 Celsius, turn off the output! Amplifier board size: length x width x height = 98x43x30mm Weight: 95 g
Use precautions:
Rated supply voltage is DC +/-65V, +/-58V ~ +/-70V range, do not over 70V! positive and negative do not pick wrong Recommended power supply DC +/-65V Recommended 4-8ohm / 10-18inch speaker Carefully check before electricity, ensure the wiring is correct. Material: CCL
Note:
Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
As small as it is, this thing makes a lot of noise. Take care not to blow up your speakers! You need a double (+ and -) power supply, at least +50V and -50V.
As for the connections, they are a bit unclear but here they are. Take the pcb in front of you with the fan on the left and the blue connector on the right (see attached photo). The connections of the blue connector from top to bottom:
speaker +
speaker -
+60V
GND
-60V
The connections of the white connector from top to bottom:
input ground
input positive

Run at 500 watts the amp produces 10% distortion and sounds awful! Turn the amp down to 380 watts and the distortion drops to 0.1 % and then the amp sounds OK

You need a mains transformer with either a 40 volts 0 volts 40 volts centre tapped secondary or a 40 volts 0 volts and a 40 volts 0 volts pair of secondary windings. The secondary windings need to be able to source at least five amps. You will then need a pair of bridge rectifiers that can handle 100 volts at ten amps and a pair of smoothing caps of one hundred volts and ten thousand micro Farads

Q:
comprei eu gostei so que veio com malcontato no ci refiz a solda voltou a funcionar e a bobina indultor esquenta muito troquei por outra mais grossa ficou normal mais fora isso e muito bom som excelente tocou 02 falantes de 15 de 250w voltarei a comprar

qual defeito do seu? o meu funciona uns segundos e fica mudo, será que refazer essas soldas faz ele funcionar normal? comprei 2 e os dois dão o mesmo defeito. E pior que esquenta mesmo, demais
What's wrong with yours? Mine works for a few seconds and goes mute, does redoing those solders make it work normal? I bought two, and they both give the same defect. And worse than it gets hot really, too much
500 watts into 4 Ohms from ***** 65 volt PSU but with 10% Distortion and it sounds awful. Run it at 380 watts and you get 0.1% distortion and it sounds OK.

Buy an unpopulated Power supply filter board, and populate it with four 10000Uf 100Volt Capacitors "make sure you populate them the right way round" and if the PCB has a place for a Bridge Rectifier install it with a 25 to 35 amp Bridge rectifier and a 35 Amp is best as it's less prone to fail, If the PCB does not have a place for a bridge rectifier on the PCB, Get a square shaped chassis Mount Bridge rectifier and bolt it down to the Chassis. Finally get a 110V centre tapped 300~500VA Toroidal Transformer

please explain me how output dc protection works? I don't see any relay on board for speakers.Then how is it working?Have you really used 'DCP' pin of irs2092?If used then reference manual of IR suggests relay to be used at output,why haven't u used such relay?

No..You need at least a 80Volt centre tapped 40-0-40 Volt 300VA Toroidal Transformer followed by a bridge rectifier, and at least *****Uf smoothing Capacitors 1 for each 55~65Volt Rail if running two modules "Stereo" with 4 Ohm Loads I would get a 50-0-*****VA Toroidal

I have two of these and I am using a 240 volt primary step down to 40-0-40 secondary 300VA Toroidal Transformer feeding two bridge rectifiers "One per channel" where each rail is smoothed with a 15000Uf capacitor per rail "a Total of 4 Capacitors", I am using a 10 amp fuse for the mains. BUT Just bare in mind I am only driving 8 Ohm loads where each channel can output 384 clean watts per channel..

Boa tarde! comprei 2 amplificador desse, ontém dia 03/ de janeiro. como faço pra ver meu pedido?, porquer não aparesse no aplicativo. Não aparesse nada là. me ajude ai.
