Unlike basic converters, every Type 3 unit runs virtually silently and includes thermal and overload protection, automatically shutting down if temperatures or wattage limits are exceeded.
With models ranging from 100W all the way up to 25,000W, Type 3 is designed for high-draw appliances, commercial equipment, and scenarios where a smaller converter would be pushed past its limits. They also come backed by a 5-year warranty, reflecting the heavier-duty construction.
Need voltage regulation on top of conversion? If your local power supply is unstable, our Type 5 converter adds both a built-in regulator and stabilizer on top of the same Diamond Series build.

Getting the right converter doesn't need to be complicated. Here's how to get started.
Check your appliance's wattage and pick a Type 3 model based on your needs. We recommend a transformer with a higher wattage than your device.
We pack and send your order from our Illinois warehouse - quickly and securely, no matter where you are in the world.
Connect your appliance to the universal output socket and plug the device into your wall outlet. It’s that simple to get reliable power.
Here's why customers worldwide have trusted us for nearly half a century.
220 Electronics has been the trusted source for voltage converters and transformers for 47 years and counting, serving customers across the globe.
Every Type 3 unit is manufactured to U.S. Military workmanship standards, with professional hand soldering on every electrical connection.
From compact 100W travel units to industrial-grade 25,000W models, 220 Electronics carries the largest range of Diamond Series converters available anywhere.
Most orders are processed and shipped within 1–2 business days from our warehouse in Elk Grove Village, Illinois. International shipping is available to many countries worldwide.
If you're bringing a 110V appliance to a 220V country or a 220V appliance to a 110V country, a step up/step down voltage converter like the Diamond Series Type 3 ensures your device receives the correct voltage safely and without damage.
Most of the world runs on 220–240V, while North America, parts of South America, and a few other regions use 110–120V.
Any appliance that is not dual-voltage (i.e., not rated for both 110V and 220V) will need a converter when used abroad. Check the label on your device; if it lists only one voltage (e.g., '120V only'), you need a converter.
The price of a voltage converter depends on its wattage capacity and build quality. Entry-level Type 1 and Type 2 models from 220 Electronics are the most budget-friendly option for occasional use.
The Diamond Series Type 3 is built for continuous, heavy-duty use and is priced at a premium.
To use a step-up transformer to convert 110V to 220V, follow these steps:
The universal outlet on all Diamond Series units accepts both US and Euro plugs.
Strictly speaking, 220V and 240V are used interchangeably in most countries. The actual supply voltage fluctuates within a range, and most 220V appliances are rated to handle 220–240V without issue.
However, if your appliance is rated specifically for 220V and your supply runs at 240V, a Type 4 or Type 5 Diamond Series converter with a built-in regulator and stabilizer is the ideal solution.
