MACHSWON OEP30WX2 Two-channel Audio Digital Power Amplifier Board High-power Module Class D 12V

Brand: MACHSWON
  • After the power amplifier board is powered, the DC voltage between the two pads of the speaker is 0V, and the DC voltage between the speaker pad and GND is half of the power supply voltage.Hands should not touch the pins of the components on the board, human interference signals interfere with the timing of the digital power amplifier, resulting in damage to the chip. A strong high voltage with static electricity on the human body will break down and damage the chip.
  • The power supply voltage should be stable as far as possible, using switching power supply and battery power supply. The power supply cannot exceed the working voltage of the board, otherwise the chip will be burned out.8 ohm speakers basically do not need to add heat sinks. If the chip temperature is higher than 60 degrees,it will stop working immediately and add heat sink fans to heat, otherwise the temperature will rise and the chip will be burned immediately.
  • When using 4 ohm speakers, the power supply voltage cannot exceed 16V, otherwise the core heat will be too high and the power amplifier will be damaged. When using 8 ohm speakers, the power supply voltage cannot exceed 24V, otherwise the high voltage will break down the power amplifier chip.
  • The speaker wiring should be controlled within 3 meters. If the line is too long, the inductance of the load will increase and the self-inductance voltage will be too high to break down the power amplifier chip. It is recommended to consider adding a diode (IN5819) to the speaker for a long line. The release of the inductive voltage protects the chip.
  • The power of the speaker must be greater than 30W to test the power amplifier normally, otherwise it will affect the normal operation of the power amplifier.We use a 4 ohm 300W stage speaker for the test.The speaker sensitivity of 95dBo must be greater than the output power of the power amplifier.Otherwise, due to the speaker power If it is too small, the short circuit between turns of the voice coil heating will cause the power amplifier to fail to work normally and damage the power amplifier.

MACHSWON OEP30WX2 Two-channel Audio Digital Power Amplifier Board High-power Module Class D 12V

Product parameters:
Product Name: Power Amplifier Module
Quiescent current: 11mA (12V power supply)
Specification model: 0EP30Wx2 power amplifier
Sleep current: <0.3mA (12V power supply)
Working mode: Class D (PWM modulation)
Recommended audio: 30-100W (the bigger the better)
Chip selection: 0EP30Wx2 (import)
Signal to noise ratio: 102dB
Number of channels: two channels
Harmonic Distortion: <0.1%
Power supply range: DC7.5-24V
Frequency Response Range: 20Hz-- 20kHz
Power amplifier gain: 36dB (the board can be set to 26dB)
Working temperature: -40℃-85℃
Input impedance: 1KΩ
Heat dissipation volume: no heat dissipation required
Output impedance: 8-3.2Ω
Dimensions: 25x 18x2.5mm (L*W*H)
Net weight: 2g
Output Power:
30W THD+N=10%(8Ω, 24V)
15W THD+N=10%(8Ω,16V)
22W THD+N=10% (4Ω, 16V)
15W THD+N=10%(4Ω, 12V)
15W THD+N= 1% (8Ω, 18V)
15W THD+N= 1% (4Ω, 14V)
Recommended work at 15W, more than 15W need to add heat sink
Note: 4 ohm speakers are not recommended for power supply greater than 16V.
Protection function: output short circuit protection (immediate recovery after troubleshooting).

Kind tips: Not recommended to use the default 36DB gain, the amplification ability is too strong, and the weak noise signal is easy to be amplified. Once the input signal is too strong, the power amplifier is easy to be distorted and seriously distorted If the amplification exceeds the output power of the chip itself, the chip will be damaged.

Package Including:
1x Amplifier board
