All voltage converters only convert the voltage and not the cycle, however most appliances and electronics will function properly with them. North American 110-120 Volt electricity is generated at 60 Hz. (Cycles) Alternating Current. Most foreign 220-240 Volt electricity is generated at 50 Hz. (Cycles) Alternating Current. This difference in cycles may cause the motor in your 60 Hz. North American appliance to operate slightly slower when used on 50 Hz. foreign electricity. This cycle difference will also cause analog clocks and timing circuits that use Alternating Current as a timing base to keep incorrect time. Most modern electronic equipment including battery chargers, computers, printers, stereos, tape and CD players, VCR/DVD players, etc. will not be affected by the difference in cycles.
On the back of your appliance, you should be able to find a label describing its specifications including its Wattage (W) or the Amperage (A) of the appliance.
Example: If your appliance consumes 80 Watts then you need a AC-100 transformer (100 Watts capacity) or higher.
If you want to operate 2 appliances on one transformer. One of them consumes 300 Watts and the other 130 Watts then you would need a AC-500 (500 Watts capacity) or higher.
If the label does not specify the wattage, but you know the Amperage (A), you can calculate it using the following formula:
Amps (A) x voltage (V) = Watts
Example: 3 Amps x 220 Volt = 660 Watts
3 Amps x 110 Volt = 330 Watts
The Servo type voltage regulators, stabilizes the voltage by adjusting the transformer to the desired output voltage. This ensures the highest precision in voltage stabilization. The relay type is all done electronically, therefore less precision.
