Product Details:
This is a 10-24V DC single power supply. Use the TPA3118D2 high performance digital power amplifier chip as the core and support 2 channel output of 30W (left channel)+30W (right channel).
Switch/Volume Control Potentiometer
Wide working voltage, energy saving design, efficient up to 90% High performance switching power supply, laptop switching power supply. You can also use it as a charging bottle, car power supply, etc.
Board is a finished board that has been soldered and tested. Follow the pictures to connect the speaker box, connect the right power supply, connect the audio input and use it.
Main Technical Parameters:
Dimensions: 2.2 (W) x 2.6 (D) x 1.0 (H) inches (55 (W) x 66 (D) x 25 (H) mm), excluding protruding part of the switch socket.
Operating Voltage Range: DC 10-24V (If the power requirements are larger than 20-24V / 4-5A, current 3-4A) If you use AC (AC) transformer power, you need to rectify and filter the DC power supply.
Please note that DC (DC) No-load voltage should not exceed 25.5V (this is very important)
