ST-2000VA 2000 Watt Step Down Transformer 220V to 110V

The ST-2000 takes your 220V mains and steps it down to 110V safely — the model with a built-in residual current device (RCD), so you get voltage conversion and leakage protection in one unit. It’s the practical answer for running US 110V appliances, tools and equipment on 220V mains, common across the Middle East, Africa and Southeast Asia.

Key Specifications

Voltage Combinations

What You Get

• True transformer-based 220V to 110V conversion — not a cheap electronic converter
• Built-in RCD for leakage protection
• Thermal protection against overload
• US-style output socket, plug and play
• 12-month warranty from delivery

Why Choose This Model

There are plenty of step down transformers out there, so let us be straight about what makes this one different:

• Real transformer, not a switcher. Many cheap “voltage converters” are electronic choppers. This is a wound-copper transformer — heavier, cooler, and built to run for years.
• Built-in RCD (residual current device). This is the model we recommend for homes: voltage conversion and leakage protection in one unit, which matters when you are running someone else’s 110V appliance on local mains.
• US-style socket standard. Plug your US appliance straight in — no adapters needed.
• Properly rated. 2000VA (2000 Watt) continuous capacity with thermal protection, so it runs hot loads without drama.
• Backed properly. 12-month warranty, CE / RoHS / ISO9001 production, and a factory that answers within 24 hours.

What It Can Do for You

This unit solves one problem very well: running 110V appliances on 220V mains. Typical users:

• Expat households in the Middle East and Africa. Bring your US kitchen appliances, TVs and tools — plug them into this and they run safely on local mains.
• Restaurants and shops. US-made refrigerators, freezers, blenders and coffee machines on 220V supply.
• Workshops. 110V power tools and machines imported from the US or Japan.
• Distributors. Stock one model that covers the most common household conversion need in your market.

A quick honesty note: 2000VA handles most household appliances up to about 2000W. For bigger draws — air conditioners, large water heaters — tell us your wattage and we will size you up to the right model rather than sell you something undersized.

Questions Customers Ask Us

Will it run my 220V appliance on 110V mains?
No — this model steps 220V down to 110V only. If you need both directions, look at our step up & step down models.

What can I run with 2000W?
Most household appliances: fridges, freezers, TVs, blenders, coffee machines, printers and 110V power tools. If it draws more than 2000W, size up.

What is the RCD for?
It cuts the power if it detects current leaking to earth — protecting you and the appliance. It is the safety feature we recommend for home use.

Can you change the socket type?
Yes — US, EU or UK sockets are available. Tell us your market.

Do you offer samples?
Yes, samples before mass production are welcome.
