Power supply transformers are an important part of many electronic devices. They take the voltage from a power outlet and change it to a voltage that the device can use. This allows the device to run off of batteries or power from a wall outlet. There are many different voltages that a power supply transformer can create. This makes them useful for a variety of devices.
Some common voltages that power supply transformers create are 12 volts, 3 volts, 9 volts, 15 volts, 18 volts, 36 volts, and 48 volts. Each of these voltages have their own unique uses. For example, 12 volt power supply transformers are often used in cars to run the electrical system. While 36 volt power supply transformers are often used in industrial settings to run machines.
Knowing the voltage that a device needs is important when choosing a power supply transformer.
