SFT-D302 is a 60W Stereo Digital Power Amplifier Module Dual Channel 102dB DC 12V Class D.
1>.Small size, only the width of two fingers;
2>.The power is very large, and it is easy to push 100-300W stage speakers without distortion;
3>.Transparent sound quality, high signal-to-noise ratio, strong resolution, and wide dynamic range;
4>.With output short-circuit protection, it will resume normal work immediately after troubleshooting;
5>.The heat generation is small, almost no heat is generated when the 12V power supply is supplied, and it can work stably and uninterruptedly for a long time;
6>.High working efficiency, up to 100%, low static power consumption, only 11mA;
7>.The base material is 1.6mm thick and high hardness FR-4 double-sided board.
1>.Pproduct name: Pure post-stage digital power amplifier board
3>.Working mode: Class D (PWM modulation)
4>.Channel type: Dual channel 2.0
5>.Power supply: DC 7.5-24V ≥ 2A
6>.Output power: 15~30W*2(4-8ohm)
7>.Recommended speakers: 30-300W
8>.Signal to noise ratio: 102dB
9>.Quiescent Current: 11mA when 12V power supply
11>.Work Humidity: 5%~95%RH
4.According to the impedance of the horn, select the approprite power supply:
1>.It is recommended to use a DC power supply such as a switching power supply or a battery. The horn impedance is different and the voltage range is different.
2>.When using a 4 ohm speaker, the voltage is 7.5-16V, the current is 2A or more, and the output can reach 22W. When it is close to 16V, the heat sink should be added.
3>.When using a 8 ohm speaker, the voltage is 7.5-24V, the current is 2A or more, and the output can reach 30W, no need to add a heat sink.
