Step Up Step Down

Step Up Step Down Voltage converters (220v to 110v)

The Dowa step or steps down transformers are available in the following models: 100, 300, 500, 1000, 2000 and 5000 watts. They change 220v AC to 110v AC or vice versa ( AC to AC). Sinewave to sinewave. These converters are meant to be used primarily when people want to convert a US appliance to work in South Africa.

Say you want to purchase a 1000 watt converter, but not sure if it would be appropriate. Then use the following method as a guide:

  • The converter should be 40% higher than the load voltage
  • If the appliance label states 120v, 60 Hz, 2A, multiply 120V x 2A = 240 watt, which is the wattage of the appliance.

Based on the above information the DW1000 or any higher rated model can be used on appliances that operate on 714 watts or less
