Currently we do use buck/boost transformers, but I would like to get rid of them entirely. Hence my desire to be able to get 120V from both 240 split phase and 208 single phase.
Some of the other challenges are that at 50hz, the motors run hotter (even though they are rated for 50hz) and the...
Ron,
I agree that the consumer homes and industrial are two different animals when it come to power feeds, but the problem is that we sell to both. Not necessarily consumer, but small university R&D labs, where all they have is a 120 wall outlet or 240 split phase. We also sell to larger...
Just trying to reduce the number of parts in inventory and eliminate the need for a heavy expensive transformer.
They are so similar (component wise) that it would be nice if we had a "universal" scheme that could be wired as required for the country/voltage.
The products are environmental...
There are purely restive loads, and you are correct, when used at 208V they generate less heat, but we account for that.
We have had problems with 60Hz stuff overheating at 50Hz. Usually we reduce the voltage to 100V in that case.
Why are clothes dryers a bad example?
Carl,
Thanks, but some of our products use 20 amp NEMA plugs. For the 120V only versions, it's a pretty straight forward configuration, everything is the same. The problem is when 208/240 is used.

Hi all,
We make industrial equipment that our customers can order to run off different line voltages. Mainly
120V 60Hz
240V 60Hz (split phase)
208V 60Hz (single phase)
230V 50Hz (European)
My question is that there are parts of our product (like small .03HP motors) that will only...
