Toroidal Transformers

All our toroidal transformers have single primary (input) and 2 pairs of secondary outputs. See Data Sheet. All are 230Vac input. All our toroidal transformers are manufactured to EN61558 EN60742, BS3535 & UL1411

If you require a different power output toroidal transformer please enquire enquiries@rhonmac-cnc.co.uk There are approximately 300 in the range. Don`t forget to Specify the Voltage and amperage required

For CNC Stepper Motor drivers determine the dc voltage required as below then the amperage.

Calculate Transformer Output Voltage and Amperage required

Determine your driver output Vdc that you want to use, divide it by 1.4 to get your Vac transformer output.

            Stepper Motor Driver voltage in Vdc/1.4 = Transformer Vac output

Amperage as follows, multiply the driver output by the number of axes then multiply by 0.67% to determine the amps required.

            Driver amps x No of axes x 0.67% = Required transformer power output.

Please note that the transformers have 2 x sets of output leads, if these are connected in parallel then the voltage stays the same but the amperage doubles up. eg, our 0300235 transformer outputs 2 x 35vac @ 4.29 amps, so connected in parallel the combined output will be 35Vac @ 8.58 amps. (usually the secondary outputs are connected this way when making a power supply). See diagram below.

  Vac Output Connect Red/Yellow pair and Black/Orange pair. Always solder and use a cable crimp then insulate with shrink tube.
