  • Difference between regulated power supply and portable power supply

    Difference between regulated power supply and portable power supply

    The topic of regulated vs unregulated power supply can be quite complex if you don't have a good understanding of electronics. So we'll break it all down in the most easy-to-understand terms in the following s.


    FAQs about Difference between regulated power supply and portable power supply

    What is the difference between regulated and unregulated power supplies?

    What's the difference between a regulated and unregulated power supply? While regulated power supplies regulate the output voltage, unregulated power supplies do not. In contrast to regulated power supplies, they provide the same level of power no matter what, meaning the output voltage will decrease as the load current increases, and vice versa.

    Does a regulated power supply affect the output voltage?

    Any variation in the input voltage will not affect the output voltage because of a voltage stabilizing device called voltage regulator used. The output voltage of an unregulated power supply, on the contrary, is not regulated meaning the output voltage changes as the load varies so they do not have voltage regulation.

    What are the different types of regulated power supplies?

    At Bravo Electro, our regulated power supplies come in various voltage ranges, such as 12V power supplies, 24V power supply, and 48V power supply to cater to different needs.
