Assuming that this question is about adapters for traveling to Another Country (not USA) then 230V is the equivalent of 220V. Just purchase a suitable adapter.
415V 3 phase is the line to line voltage. The line to neutral of this supply is 230V single phase. Therefore you use one of the phases and the neutral.
Voltage x Current = Power So Power / voltage = current Now you do the math
You can get a transformer that converts the UK's 230V power to 120V, but you cannot get a transformer that will convert from 50Hz to 60Hz. Often, US equipment can work, except that they will work hotter and less efficiently on the 50Hz power. Consult your clipper and trimmer documentation - you may find that it will work just fine on 50Hz.
3 amps
you divide the volts by the ohms
230V/50Hz
As of 2000, Australian power points supply AC 230v at 50hz. Pre-2000, it was 240v at 50hz.
The power adapter need 230v, 50Hz supply
No! Normally not, the recistance in the windings is to hig on 60Hz and the pump motor has not power enough to work propelly. This happened to myself when I connected my Whirpool AWE 7519 to 230V 60Hz. Europian model for 50Hz.
It is not advisable because the motor would run 20% faster which might produce damaging overpressure in the thermal circuit.
Swedish outlets have 230V, 50Hz like the rest of Europe.
Mains voltage in new Zealand is 230v AC 50Hz. Mains plugs are 3-pin, with a vertical Earth, and two inclined pins for Phase and Neutral. (Same as Australia) If the charger you are referring to is the type that plugs into a cigarette lighter - these are common to all (?) cars.
no way because frequency cannot change
yes, it can be used - single phase voltage of 230v. 50HZ is important
It is an AC supply with an rms voltage of 230 v and a frequency of 50 Hz, as used throughout Europe.
220V , 50Hz
Mains refer to the general-purpose alternating current (AC) electric power supply. In the UK, households receive 230v of electricity for normal house hold use at a frequency of 50Hz. The advantage attached with the use of alternating current is the ease with which it can be stepped up or down to suit the purpose using a transformer.
