Custom Rectification and filtering power supply with speaker protection integrated rear power amplifier board PCB empty board

1. The filter capacitor is 10000UF/63V*2 (Ruby 30*45 diameter*height).

2. The bridge stack is imported 25A/800V, and the high-current PCB traces are all tinned, suitable for most post-stage power amplifiers (such as discrete post-stage, LM3886, TDA7293, TDA7294 and other circuits)!

3. The board size is about: 100MM long, 68MM wide, 52MM high.

4. Input voltage: dual AC24-36V. With +- dual power indicator (red light and green light).

If the voltage is less than AC24V, you need to contact customer service to explain what the voltage you entered is, we can modify it for you. The input terminal voltage is less than 24V, and the resistance value of the large resistor next to it is also changed to small, 100 or 50R

5. With horn protection function (power-on delay is about 3 seconds, instantaneous shutdown, midpoint DC protection, starting voltage is about 0.7V), the relay is imported from Japan OMRON G2R-2 (DC12V); with protection status indicator Light (the power-on delay is about 3 seconds, the relay is closed, the blue light is on, and this light can be selected for power indication when installed).

PCB size: 100*68*1.6 MM,
