## Description

This product is a relay-type high accuracy voltage stabilizer and transformer. Ideal power source for voltage regulation for modern household electrical appliances. Designed to transform 220V to 110V up to 3000 watts, it can safely be used with a wide range of electrical equipment, including home appliances, tools, computer equipment, etc. Ventilated design for continuous use. It is applicable for areas with large fluctuations of electric network voltages. The manufacturer recommends a transformer that is 25% higher than the wattage you need. You should know that you will never damage your appliance with a higher voltage transformer, however if you buy one that is not powerful enough, it will not work. Remember to leave at least a 100% slack for the transformer. Some items, such as laser printers and power tools, spike when you turn them on. For these types of situations you need to buy a transformer that is at least 3 times the item's capacity. Use Amps to calculate Watts: Volts (x) Amps = Watts. For example 110 Volts x 5 Amps = 550 Watts * In many regions, voltage fluctuations might be within ±10% of the nominal voltage, meaning the voltage could vary between approximately 198 volts and 242 volts. However, this can vary based on specific regulations or utility practices in different countries or regions. Rural areas may experience dramatic voltage fluctuations due to long power lines. These voltage fluctuations can cause lights and display screens to flicker, and heating systems to take longer to warm up. They may even cause computer systems to lose data or become damaged. In industrial settings, overvoltage and undervoltage can cause serious damage to expensive equipment like automation machines. Automatic Voltage Regulators (AVRs) are the most effective way to protect electrical appliances from voltage fluctuation damages.

## Questions & Answers

**Q: Es igual a un inverter....utilizar bateria de carro?**
A: I think it is better than an inverter since you can physical see the voltage supplied at any moment.
Car battery is too heavy.

**Q: Will this product work with a south african plug in the usa?  (using a south african device in the usa). does the outlet receive a sa plug?**
A: hello,
No, this item will only work in Africa with 110 volt devices. Will not work in the United States.
Regards

**Q: Does it also bring the frequency from 50 hertz to the 60 hertz required bu US appliances ?**
A: I didn’t use it yet i’ll Send it in my country

**Q: Why is the output voltage in the red? Can i plug in my device without damaging?**
A: I have used the step down transformer for 2 years without any issues. Please check your load, is the rating 110V or more? Switch on the transformer without any load and check the Voltage meters to see if everything is normal.
