Technical information sheet of JC1000 STEP UP AND DOWN TRANSFORMERS-1000 WATTS
Who has ever not suffered a damaged electrical appliance from an electrical surge? The JC 1000 has a maximum capacity of 1000 watts. Japan uses high end electrical appliances just as America. It is necessary that for all electrical appliances to run properly, there must be an appliance to provide a uniform flow of electric current. It can step up the current from 110 volts to 117 volts and step down current from 117 volts to 110 volts. The internal circuit is well built so that it can take the load of overflow or underflow of current. This is available online or you can directly call Sam Stores.
Features Model# JC1000 Step Up and Down Transformers 1000 watts For use in Japan and USA Step up/step down 117<---> 100V 100<--->117V
The manufacture recommends you purchase a transformer that is 25% higher then the wattage you need.
You should know that you will never damage your appliance with a higher wattage transformer, however if you buy one that is not powerful enough, it will not work.
Use Amps to calculate watts
Volts (times) Amps = Watts, For Example 110V x 5A = 550W
Remember to leave at least a 100% slack for the transformer. Using them to maximum capacity will eventually burn the transformer out after prolonged use. 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 items capacity.
