To determine the Ratigng of the Equipements if not indicated on the equipment, Use the Formulae;
Volts x Amps = Watts (i.e. 110V x 0.5 AMPS = 55W)
Choose the transformer rated above your device’s watts usage By 25%-50%
If your equipment has a motor, Buy a Stepdown transformer that is rated 25%- 75% Above you Equipment Wattage
Step Down Transformers
A Step-down is commonly used in Kenya with Equipment Bought in The USA or Elsewhere that require a 110v AC input The Stepdown transformer decreases the voltage incoming to the site by increasing the electrical current.
Volatge and Current Transformers does this by converting the high incoming voltage in the primary winding to the necessary lower voltage in the secondary windings.
Voltage may need to be ‘stepped-down’ in order to be at a voltage level that matches the devices used, whether in a small manufacturing facility or a factory covering thousands of square feet.
