Dc Power Supply Wiring Diagram. It conducts electricity from the engine to the alternator while the voltage detecting cable senses the. Always put a fuse between the battery and the power inverter so that if a short circuit occurs the fuse protects the installation.
Modern personal computers universally use switched mode power suppliessome power supplies have a manual switch for selecting input voltage while others automatically adapt to the mains voltage. If youre trying to find out the dc voltage of an ac power supply then use the formula v ac 2 where v ac is the ac voltage. Here we will discuss the working principle of an smps circuit.
However many appliances and electronics use direct current dc which provides consistent power to the device.
The circuit comprises three main wires. The diagram above is the 5 pin relay wiring diagram. The output voltage is compared to a reference voltage derived for example from the front panel settings of the power supply and the difference is fed to the transistor to. Also it is a high efficiency regulator using an ic regulator ua723 and power transistor tip3055.
