Using wrong line source voltage and frequency





2003

Sir, I would like to be clarified if I have a machine rated at 230V/ 50 Hz, and the line source available is 220V/ 60Hz. Is there any devastating outcome to my instrument if I will plug it to the available line source?

The voltage isn't the main problem (most equipment is built to handle a ± 10 percent voltage variation). But the frequency difference is a big problem for many reasons. This is a question that can't be answered except by the supplier. Most things won't work, but there are a few industrial motors that are built robustly enough to run under these circumstances.

As Ted says, the voltage is no real problem, but the frequency is a major one. Many pieces of electrical equipment use the frequency to run their clocks and other time-based items, so they won't work properly, if at all. It is possible to buy a frequency converter, but they are not easy to come by, are usually quite expensive and tend to be quite big. As far as I know, the USA (and perhaps Canada) are the only other major countries that use 60Hz, whilst most of the rest of the world uses 50Hz, so it may be worth trying to source the converter from the USA. You may be better off getting a 60Hz replacement machine - try a trade-in.

Major problem will be on AC motor speed, which will be a bit difference RPM for 50/60 Hz and heat more if run on difference frequency, there are no need to consider for the cooling fan.
