Switch mode power supplies are a very common type of power supply. A switch mode power supply uses a switching regulator to convert AC mains power to low voltage DC and it does this very efficienctly. Typically a switch mode power supply is much more efficient than a linear power supply. Switching power supplies also tend to be smaller in size than linear power supplies and use less raw material making them more competitively priced. PowerPax are one of the UKs largest suppliers of power conversion products and we have an extremely comprehensive range of switch mode power supplies held in UK stock for immediate delivery.

The ranges below provide an overview of some of the core ranges of switch mode power supplies we offer. For a more detailed over view please visit our main power supplies page
