Defender 3kVA Portable Transformer 110V 3000W (E203010)

Product Information

And if you’re working with specialized loads, such as those found with motors or medical equipment, your kVA requirements may differ substantially. Our transformers are generally double wound, enclosed in a steel or insulated enclosure, usually offering high levels of ingress protection. Please make use of any product reviews or youtube clips we have available to learn more about the item. Large facilities and industrial processes require substantial amounts of power, and they need dependable transformers to convert the energy coming from the power plant into a form they can use for their equipment and building utilities.

A 3kVA 110v Portable Transformer featuring 2 x 16A outlets designed for use with corded products such as drills, grinders, saws, lighting products, heating and ventilation products.

These transformers are common in industrial and commercial operations, including many types of lighting applications.

Most kVA ratings are whole numbers, and many, especially in the higher ranges, come in multiples of five or 10 — 15 kVA, 150 kVA, 1,000 kVA and so on.

It involves using a straightforward formula to generate your kVA requirements from the current and voltage of your electrical load. We provide a range of transformer services to keep your business operating smoothly, including transformer repairs, rebuilds, retrofits, rewindsand emergency replacements. In this case, i 1is 6, i 2is 4, and V 2is 10, and if you plug those numbers into the formula, you get 6/4 = 10/V 1.This transformer did good job for us thought it might come with plug but it doesnt it has to be wired in. In many industries, including health care, manufacturing, electrical contracting, higher education and corrections, reliable, high-quality transformers are essential for keeping operations running efficiently. Items found to be defective within 12 months of the units original purchase date will be repaired or replaced without cost to the owner for the parts and direct repair labour. Maybe you know your transformer has a current of 4 amps and a voltage drop of 10 volts through its secondary coil.

To determine your kVA size, you’ll need to make a series of calculations based on your electrical schematics. Alternatively, you may have the kVA of your transformer and want to calculate the necessary voltage. So if you’re working with a three-phase transformer, instead of multiplying the voltage by the amperage and dividing by 1,000 to get the kVA, you’ll multiply the voltage by the amperage by 1. In that case, you’ll probably need to replace your transformer, and when you do, you’ll need to select one with the correct kVA for your needs. I bought a 5kva transformer and needed it within 3 days as my other one had stopped working and I had an important task to complete.The equation for three-phase transformers, which we’ll discuss in more detail below, is also slightly different. There are many useful tools online to aid you with transformer rating and design, here is a useful link; Transformer Basics How can we help?

A good rule of thumb is to multiply the voltage by the amperage and then multiply by an additional start factor of 125%. It’s easy to talk about transformer size calculations in the abstract and come up with an array of numbers. To see the benefits of quality, high-performing transformers in your business, partner with ELSCO Transformers. You can calculate the voltageof the secondary circuit by using a ratio of the voltage drops through the primary and secondary circuits, along with the number of circuit coils around the magnetic part of the transformer. It does not apply if damage is caused by accident, misapplication, abuse, alteration, tampering or faulty external wiring, incorrect or fluctuating power supply.NOTE: If you need assistance with circuit protection devices such as fuses or breakers, or wire sizing, please consult a licensed electrical contractor or electrician in your area who will be familiar with state and local codes.
