Custom Transformer

OEM and ODM

Two routes, and most customers know which one they need before they ask. Under OEM you supply the drawings and the specification — ratings, materials, dimensions, terminal arrangements, nameplate layout and documentation format — and we build to it, under your brand. Under ODM you supply the requirement instead: capacity, primary and secondary voltage, frequency, current, duty cycle, cooling, ambient and altitude, and the standards you have to meet. We return the design, the drawings and the test schedule for your approval before manufacture starts.

Both routes carry the same routine testing, the same traceability and the same support for third party inspection and witness testing. Both can ship directly to you — our import and export registration is in place.

    Frequently Asked Questions

    What is the difference between OEM and ODM supply?

    Under OEM you supply the drawings, specification, brand and documentation format and we build to them. Under ODM you supply the performance requirement instead and we return the electromagnetic design, thermal design, drawings and test schedule for your approval.

    What information do you need to quote a custom transformer?

    Rated power, primary and secondary voltage, frequency, phase, rated current, vector group, impedance, tap range, cooling method, duty cycle, ambient temperature, altitude, enclosure and installation environment, applicable standards, and quantity.

    How long does a custom transformer take?

    Design and drawing approval comes first, then manufacture and testing. A standard distribution unit is quicker than a rectifier or furnace unit with a custom vector group and cooling arrangement, which is scheduled as a project.

    Can I have my own brand on the unit?

    Yes. Under OEM we build with your nameplate, your documentation format and your packing specification, so the unit arrives as your product.
