To determine which below Step Down transformer you need please check these five questions first:
Select from our Step downs transformers based on how many watts your device uses.
Choose the transformer rated above your devices watts usage.
E.g: Playstation 3 uses 380 Watts so you need the 500 watt rated stepdown transformer.
If a motor is included then you should select a stepdown rating approx 25% higher than your motor as a buffer.
Motors have a higher power use on the stepdowns and startup currents which need to be allowed for.
Most motors have a rating plate on them with their Power and Amperage rating.
If so, how critical is this timing device?The Transformer cannot change the Frequency. It is 50Hz
If a timing device is included the speed of the device may change due to the frequency change, 60Hz to 50Hz (eg old clocks, motors / fans/microwaves ) Most modern electronic devices should not be affected. Read more about frequency
Calculated as Watts = Amps x 110Volts (eg 5 A x 110 V = 550 watts)
Check total watts of all devices this must be less than the VA (Watt) rating of the stepdown & get a US Powerboard.
