    Transformers

    RS stocks a great range of industrial power transformers. You can choose from PCB mounting, toroidal, chassis, DIN rail mounting, and more. We also have a site safety power transformer range and 110v transformers. All our power transformers are sourced from trusted brands such as Block, EPCOS, Wurth Elektronik and our own RS PRO.

    What is a power transformer?

    A power transformer is an electrical device that supplies electricity from one circuit to another by changing the magnetic field. They're used in residential and industrial environments

    What types of power transformers are available?

    At RS, we offer a range of power transformer types:

    Audio Power Transformers: for increasing and decreasing voltage in amplifiers and high-frequency audio and voice circuits

    Autotransformers: also known as a step-down power transformers, they are small, cheap and light due to only having one coil as opposed to those with a secondary winding coil

    Chassis Mounting: these power transformers come in different sizes with holes for mounting to a chassis

    Current Transformers: these power transformers measure the current of another circuit

    DIN Rail & Panel Mount: these power transformers have the capacity to be mounted to a flat surface, panel or DIN rail via mounting holes

    LAN Ethernet Power Transformers: isolation and signal conditioning for transmission and correct reception of voltage over Ethernet

    Lighting: power transformers that are specifically designed to work with lighting, most commonly dimmer switches

    PCB Power Transformers: printed circuit board transformers control the voltage or current moving through the board

    Safety Site Power Transformers: providing protection in transformers through isolating mains power supply minimise shocks and overloading

    Switch Mode Power Supply (SMPS): these power transformers are used primarily in PCs for switching from AC or DC to DC power

    Telecom Power Transformers: voltage isolation before transmission for use in homes

    Toroidal: power transformers in the shape of a ring or doughnut

    Wall Mount Power Transformers: for use in hazardous locations or harsh industrial environments

    We also have a range of chip and transformer-line baluns, coil formers, mounting kits, terminal covers, ferrite cores as well as variac brushes, connectors dials and knobs.
