(AC100-115V,AC110V,CP3 CP4 short
AC200-240V,AC220V, CP3 CP4 open)
2. Speaker load: 4-8Ω
3.RMS power: 500W
4. Peak power: 1000W
5. Channel: Mono
6. Frequency response: 20HZ--20KHZ
7. Size: 200X130X42mm
Features:
1. The power is very large, and the fan needs to be added with heat. From the right digital amplifier section to the left side of the switching power supply section.
2. Temperature protection: The temperature of the radiator rises to 85 °C, the protection starts automatically, and the amplifier stops working. After the temperature of the heat sink drops, the power amplifier automatically starts to work.
3. Overload protection: The load is overweight and will protect
4. Speaker protection: The output has DC, the relay is disconnected, and the speaker is protected .
5. Anti-shock: There is NTC thermistor at boot to prevent inrush current
6. The start relay is delayed.
Packaging:
1PC
Note:
This power amplifier board has high power and large heat. Long-term high-power work requires DC 24V fan. ![](https://ae01.alicdn.com/kf/Hd323642dcd8c41e2a7c00669caf2983cF.jpg)
