Then, solder the components on the printed circuit board, and note that the market prospects for printed circuit board assembly are promising. However, due to the active market for circuit board components, you need to work hard to determine the product you are using, otherwise you will immediately know what you are using. The products you need to repair include: wet printing, through-hole silver deposition, connector holes, pins, device sockets, heat dissipation devices, electronic connectors, automotive connectors, wiring terminals, test clips, plug sockets, electronic connectors, plugs and sockets, and can also be customized according to your special requirements.
● Debugging status: TIM-9914, no fault displayed: not working, TIM-9914 not started, fault displayed: leakage 1 (5V/2A),
The cooling fan motors U and N are connected to around 2W, and the two wires are directly connected to the power supply. After 3 seconds, they do not work;

The cooling fan motors U and N are connected to OE1-3 after 220V, 110V, 48V, 24V, 36V, 48V, and the other two wires are directly connected to O2 wire;
The fan motor does not have low voltage (0~+24V,+24V), but can be wired 180 degrees by hand, with a capacity of 4-8, 12, and 15 times.
