Fixed Installation Car Power Adapters: The power that comes into your vehicle from the battery may be too high for powering some of the modules and devices, so the manufacturers will often utilize power adapters to ensure you are receiving the right voltage for the devices. They are available at various input and output voltages to ensure the best and safest performance. They also have surge protection and short circuit protection. Isolated DC-DC Converters: As mentioned, these have internal transformers that will transform the input to a different output voltage for use with your equipment. With this converter, the output is isolated from the input. Non-Isolated DC-DC Converters: As the name suggests, they do not have any isolation between the input and output. They are typically used for smaller voltages. They can step the voltage up or down, and some of the converters have the ability to do either.
