SMAKN Class D 2 15w DC 12V Mini Digital Power Amplifier Board
SMAKN Class D 2 15w DC 12V Mini Digital Power Amplifier Board
First, the main technical parameters: Supply voltage: DC 7V-15V Maximum output power: 10W + 10W (8 Euro trumpet); 15 + 15W (4 European speakers) Efficiency:> = 90% Shutdown Current: 4uA Quiescent Current: 20mA SNR: 80dB Total harmonic distortion: (50W / 1KHz / 12V / 8Ω - 0.1%) Frequency range: 20Hz-20KHz Input impedance: 15KΩ Speaker: 4-8Ω Voltage Gain: 33dB The amplifier board size: LWH = 30mm 25mm 2.5mm Weight: 2 grams Second, the use of note: The power supply voltage limit is 24V, do not over! Otherwise, easy exploding capacitors, AC rectified voltage peaks do not exceed 25V. Do not exceed this voltage, the positive and negative do not reversed The power supply is recommended for 22V, 200W power supply is better than filtering horn speaker recommended 15-50W Do not short-circuit the audio output to each other or shorted to ground
