Correct Selection

choosing the right step down voltage converter for your american or japanese appliance:

to and from ×
please read these easy tips before purchasing your step down voltage converter to ensure you have chosen the right one for your appliance:
  1. what size converter do you need?
    first we must establish what is the total power draw in watts specified on your 100v japanese appliance?
    on most appliances there will be 3 sets of numbers which should be displayed as follows:
    “input 100v 60hz and either xx amps or xx watts”
    as long as you have 2 of these values you can calculate the third - please use the calculator above.
  2. what is your appliance? will your appliance be used for a brief period or Running continuously?
    all step down converters in the 8zed range, have two power ratings. the 1st rating is for 1 hour use or less, the 2nd power rating is for over an hour or continuous use. these are safety power rating parameters to ensure the converter Runs cool and lasts for many years. 
    many users tend to hide the converter away behind appliances or in cupboards (in some cases not allowing adequate airflow) hence it is important to adhere to the recommended air flow safety allowances to avoid overheating.

    example: if your appliance states 100v 60hz and 5a then the max current draw will be, 100 x 5 = 500watts. the best matched transformer in this case is the stis-600tp, but if powering for over an hour then select the stis-1200tp.
  3. does your appliance have a motor, pump, heating element or compressor?
    appliances including one of these elements may require a larger transformer model than indicated by the power draw specification. these high power surge elements have large start up power requirements. typically, you should select a transformer 3 to 6 times the stated power draw.

  4. is your appliance two pin or three pin?
    all 8zed step down converters have the universal socket to suit all three variables. two pin, two pin keyed “one pin is thicker” and the three pin “two flat one round”
  5. why won’t my appliance plug in?
    all 8zed stepdown converters are manufactured using high quality pressed metal pin sockets and in the initial instances of usage a slight amount of force will be required to plug your appliance in.
  6. what about the frequency of 60hz to 50hz?
    what this means in regards to your appliance.
    in cases of motors they will turn 8~10% slower. so in case of fridges the temperature will be slightly higher hence the need to adjust the sensor to the next adjustment. many items with speed controls are not affected, such as sewing machines and most turn tables. in minor cases there are “digital” speed controllers used on turntables which will be affected.
    home av receivers are mostly immune but in some cases and field studies there are some chipsets that control the video signal that are affected. one example is onkyo av receivers which cannot sync picture to the tv.
    for game consoles, please seek further assistance, as each console is different. in some cases a converter cannot be used.

    now for all the cooks, kitchenaid mixers , all ksm 150 series ie: the general ones, you will need the st-500.
    for all the kitchenaid pro’s you will need the st-1000.
