30Wx2 High-Power Stereo Digital Power Amplifier Board 12V/24V Power Supply DIY Power Amplifier Module DY-AP3015Item NO.: DY-AP3015

DY-AP3015 Digital Power Amplifier Board

Parameter Properties:

● Product name: 30W stereo digital power amplifier module

● Product model: DY-AP3015

● Working voltage: DC: 8~24V

● Operating mode: Class D (PWM modulation)

● Number of channels: stereo (dual channels)

● Maximum output power (@ 1KHz): 18W * 2 @ 12V 4 Ω, 10W * 2 @ 12V 8 Ω, 15W * 2 @ 16V 8 Ω, 20W * 2 @ 20V 8 Ω, 30W * 2 @ 24V 8 Ω (radiator is required)

● Adaptive horn (30W~150W): 4 ohms (8-12V power supply), 8 ohms (8-24V power supply)

● Module protection mechanism: power reverse connection protection, short circuit protection, self recovery overheat protection

Be Careful:

1. In order to improve the performance of the module, it is recommended to add a heat sink to the power amplifier chip in the application scenario where the work exceeds 20W * 2.

2. The volume adjustment knob is equipped with a switch. If you turn it clockwise to hear the click sound, it will turn on and continue to turn up the volume. If you turn it anticlockwise to hear the click sound, the amplifier will turn off. After the factory test, it is turned on by default.

Precautions:

1. The recommended power supply voltage is 8~24V DC. If it exceeds 26V, the chip will be burned, and if it is lower than 8V, there will be noise.

2. The power supply shall not exceed 12V when connecting a 4 Ω horn and 24V when connecting an 8 Ω horn.

3. The power supply current is recommended to be above 2A.

4. The working power of the module exceeds 20W * 2, and heat sink is required

5. Ensure that the input sound source signal is 0.5V~1.5V

6. The horn cable shall not be too long, and it shall be suitable within 1m

7. Pay attention to electrostatic protection. Before touching the power amplifier board, release the static electricity on your hands to prevent the power amplifier chip from being broken down by static electricity. Digital power amplifiers are sensitive to static electricity.

8. It is recommended to use the horn with a rated power of 30W or above to avoid the horn burning due to heating
