MEP803a Real World Voltage Adjustment Limits

[Haoleb]

Let me preface this by saying, Yes I could test this on my own set. However, it is currently stored away unless needed for power backup and would involve a lot of work to deploy it and then store it again for a simple test so it is so much easier to just pose the question to someone who may already know the answer.

Any ideas on the actual adjustment limits for the voltage range? At my workplace we have a piece of equipment that uses single phase 208v motors and we are looking to test this equipment across a wide voltage range to see if a new motor is suitable as our customers have a wide voltage range from 190v up to 240v

I figured that I could test the upper end of the spectrum on single phase mode probably up to 250v or so but it is the lower end I am worried about. I doubt it will go down to 210 or lower in single phase mode but in 3 phase mode any idea how low I could adjust down to?

You should be able to adjust it safely within a range of +/- 10%.

To cover the voltage range from 190 to 250 you'll need to use single phase and 3 phase settings on the generator.

3 phase variac

Or 3 variacs coupled together.
