Feature:
1. Product Information: Power amplifier chip TPA3255, working voltage range 18-50VDC, limit 53V. It is recommended to use a DC power supply with a voltage of 36-48V and a current of more than 10A. The higher the voltage, the greater the output power.
2. Adaptive Speaker: 3-8 ohms, 50-300W in BTL dual channel mode. PBTL mono mode 2-8 ohms, 100-600W. Heat dissipation mode, temperature control automatic air cooling, or manual selection of fan rotation.
3. Gain Selection: Potentiometer 10 speed adjustment, 26dB-36dB. Bridge mode, power off first, switch the DIP switch No. 1 to the ON position, output R+ L+ short circuit parallel output, R-L - short-circuit parallel output. In BTL mode, 2x300W 50V 4 Ohm , 160W 50V 8 Ohm . Under maximum power PBTL mode, 600W 50V 2 Ohm , 300W 50V 4 Ohm , 160W 50V 8 Ohm .
4. Protective Mechanism: Input undervoltage, overheat, overcurrent, short circuit prevention. No input anti reverse protect, positive and negative terminals can not be reversed.
5. Enlarged Heat Sink: Equipped with large and efficient heat sink, the device ensures stable operating under sustained high power output. It effectively dissipates generated heat, enhancing the operational efficiency of the amplifier board and ensuring outstanding performance under high loads.
