    Linear Power Supplies

    An embedded system is a computer system with a dedicated function, embedded as part of a complete device often including hardware and mechanical parts. A power supply sub-system is one of the most important aspects of any embedded system. Embedded linear power supplies are used to regulate the high voltage DC from battery power source to low voltage DC suitable for the embedded system.

    How does an embedded linear power supply work?

    Embedded linear power supplies accept the load current at the higher DC input voltage, reduce the voltage and deliver the current at reduced voltage. They provide clean output voltage with low noise. They dissipate the extra power as heat, so you need to have heatsinks.

    What are embedded linear power suppliers used for?

    Embedded linear power suppliers protect sensitive loads against excessive voltage and stabilize tensions so they are suitable for precision applications (for example laboratory power supplies and hi-fi systems). They are easy to install and connect and their efficiency is up to 90%. Embedded linear power suppliers have different numbers of outputs, from one to four. They usually have safety mass straws.

    What are the different types of power supplies

    Open frame linear power supply

    The power supplies are usually available in open frame format. In other words, open frame refers to the fact that the power supply is made out of a PCB, but without any enclosure. Only the end equipment used in the power supply would be providing physical protection to it.

    Closed frame linear power supplies

    Open frame power supplies are not the best to be used in most situations. For example, there can be mission critical applications, where you will need to offer extra protection to the power supply. This is where the power supplies are provided with an external enclosure. There are situations where the power supplies come along with an conformal coating as well. It can provide extra protection to the power supply against humidity, contamination, and dust.

    If you are looking forward to getting linear power supplies, take a look at the selection of products we offer. At our store, you can end up with buying the best closed frame or open frame linear power supply that will cater to your needs.
