Desktop centralized power supply distribution board

Input 12V, anti-reverse connection. (For other voltages, calculate the voltage dividing resistor by yourself, up to 24V)

Allowable input 10-13V. lower or higher than the cut-off input.

4 channels of power output, preset 3.2A x 3 channels, 4A x 1 channel.

If the output current exceeds the set value, the output will be cut off with short circuit protection.

After overcurrent or short circuit, the output will remain disconnected until the downstream load is removed or the power output is reconnected.

One channel also carries a 3A load. A short circuit on another channel will instantly pull down the main power supply, about 2ms.

It is good to use large power sources to provide centralized power supply, but it is too powerful. In case the output is short-circuited. It's so scary. In the past, the only solution I could think of was to add insurance, but it was always troublesome. If it breaks, you have to replace the insurance.

it's good now. No more fear of short circuit. In case of accidental short circuit, it can be restored immediately.

You need to think about how to arrange the desktop. All peripheral power supplies want to be connected to this large power supply.
