European Products(IEC Standards) on American Voltage Systems(ANSI)

12/31/2010 6:35 AM

Can European products that are manufactured based on IEC standards be used to be plugged to a system that uses American standards like a voltage and frequency? For example my system is 230V/133V system and my client want to use an equipment that are rated 220/127 volt.. IS this safe? From my research it says it is okay to use the particular product because the peak value of the voltage is 127(1.414)= 179.6V and hence can still withstand the rms voltage at the source of 133V. Any thoughts?

Anything rated at 230 is ok on 220.
The European 'standard' is a fudge to cover a variety of voltages across Europe and allows 10% variation or somesuch.
UK is notionally 230 but is actually 240and comes under the 220/230/whatever umbrella.
I reserve the right to be wrong about the fine detail here, but you get the drift.

And now a word about frequency. European systems are 50 Hz and American power is 60 Hz. So any motors you have will be running at 6/5 the speed they would at 50Hz. This may, or may not, be a factor depending on load and motor efficiency.

Many motors are dual rated, but the speed is determined by frequency of the power supplied to the motor.

Like was stated,the difference in frequencies 60HZ American and 50HZ European.The 50HZ creates more current draw, therefore more heat is produced.You need to keep all of this in mind and adjust accordingly.

You can do it if the RMS is in the same range. Good thinking buddy!

The only problem you may have is that due to the frequency changes, the equipment downstream from the elements will run hotter and of course yours will run hotter, but if you have enough heat dissipation it should take care of if

Regards.

Only equipment not using Time and Speed elements will have no problem.

But where speed and time is important you have to think thoroughly to use.

As far as Voltage is concerned equipment's nominal rating of 220 works well from 200 to 240V
