Product Description
Made by one of the leading manufacturers in the industry, the Goldsource ST series step up/down voltage transformers offer you a safe, reliable, affordable & convenient solution to converting voltages from 110-120 volts up to 220-240 volts or from 220-240 volts down to 110-120 volts for both home use & industrial applications. The ST-3000 is rated at 3000 watts maximum. It features a heavy-duty cord with a standard US 3-prong plug plus a free American to German outlet plug adapter. There are a total of two grounded outputs on the front panel, one is designated for 120 volts and the other is for 220 volts only. They both are standard US outlets and can be used simultaneously. For safety, it's recommended by the manufacturer that the voltage transformer's maximum power should be equal or greater than the power rating of your appliance multiplied by 1.5. For example, if you have an appliance rated at 100 watts, you will need to pick a transformer with a maximum power of 150 watts or greater.
- Step Up/Down transformer converts 220-240 volts down to 110-120 Volts or 110-120 volts up to 220-240 volts.
- Simultaneous 3-mode Output: 5V (USB) / 120V (Standard US outlet) / 220V (Universal outlet)
- Four input voltages selectable: 110V/120V/220V/240V
- All range fuse protection with two spare fuses included.
- CE certified & 3-year manufacturer's limited warranty.

The product is well equipped to do this. It has different settings for input of 110v, 120v, 200v, 220v, or 240v. You easily select the voltage that will be coming in by moving a plug in the back. The power cord is a standard USA polarized plug with ground, but in the box it comes with a plug adapter for Europe. This didn't help me too much in Brazil, but it is not a big deal to get a $1 or $2 plug adapter to make it fit here or anywhere else.After you plug it in, switch it on, and then you have two options on the front from which to get power. You can receive either 110v or 220v via two USA type outlets (with ground) in the front. Then just plug in your electronic equipment and bingo, you have the correct voltage and hertz to not burn out your motors! I am using the product to step down the voltage to 110v for my stuff, but...

This corresponds to 1366 Watts, which converts to about 1.8 Horsepower. I assume there are losses in the system, so the actual rated pump HP is probably more like 1.5. Frankly I was surprised that my generator was able to start the pump since it is only a 3500 Watt generator. The starting current is about 16 Amps at 220V, and the generator nearly stalls, but then catches up and runs fine after a few seconds. The transformer shows no signs of strain, does not get hot, does not hum loudly, and definitely does not smell at all. 3 of 3 people found the following review helpful Durable, By Brooks "Nomads" (West Africa & USA) - See all my reviews Amazon Verified Purchase This review is from: Goldsource STU-3000 Step Up/Down Voltage Transformer Converter - AC 110/220 V - 3000 Watt (Electronics) We live in Africa and have burned up many transformers. This one has held on well while being used with a KitchenAid and an expresso maker. |
