QB200A CPU & stdby Power Supply
I have developed this pcb for a special project I have been working on for a long time. The board can control a very advanced 8-channel power amplifier. There are many features, including eight communication ports for each power amplifier, over voltage detector and shut down function. The amplifier runs on two phases on the mains. Therefore, it can easily go wrong if they have been swapped. If this happens then the pcb will not turn on the large power supplies. Nothing happens to this pcb. It can withstand 600 volts AC. There is also IR receiver, USB communication, WiFi, three fan outputs and three 12 volt outputs for power relays which can switch the power supply to pure class A mode (half supply voltage and double current).
