1pcs DC12V-24V Audio Speaker Digital Power Amplifier Board Dual Channel 30W+30W TPA3118
Specification:
(1) This model is powered by 10-24V DC single power supply, with TPA3118D2 high-performance digital power amplifier chip as the core, and can support 30W (left channel) + 30W (right channel) dual channel output.
(2) Potentiometer with switch / volume adjustment.
(3) Wide working voltage, power-saving design, efficiency up to 90%. It can use switching power supply with good performance, laptop switching power supply, charging bottle, vehicle power supply, etc
(4) The board is a finished board that has been welded and tested. Connect the speaker box according to the drawing, connect the appropriate power supply, and connect the sound source input. It can be used.
(5) 2 kinds of sound source input ports
Main Technical Parameters
Overall Size: 55x66x25mm, (excluding the potentiometer protrusion:15mm)
Voltage Range: DC10-24V (current 3-4A, if the power requirement is higher than 20-24V /4-5A). If an alternating current (AC) transformer power supply is used, it must be converted into a direct current (DC) power supply by rectifying and filtering. Note that the DC no-load voltage should not be greater than 25.5v (this is very important)
Sound Source Input Sensitivity: 600-800mV
Frequency Range: 20Hz - 20KHz
Speaker Impedance: 4-8Ω
Output Power: 12V/8Ω =10W x 2; 12V/4Ω =15W x 2;
19V/8Ω > 20W x 2; 19V/4Ω > 30W x 2;
24V/8Ω > 30W x 2; This is in accordance with the above test conditions, and the actual test data on the instrument are related to the output power, power supply voltage / current, speaker impedance and sound source input. When the power supply voltage / current is sufficient, the power supply voltage is usually higher, and the relative output power can be larger. The output power of speakers with different impedances is also different. Generally, the power of speakers with smaller impedance is easier to be larger. For those who require high power, please understand the above parameters before bidding.
Package Include:
Amplifier Board x 1
