Hi there. So here goes.
I have been having issues with a replacement chiller unit that requires 230VAC single phase.
An identical unit was running on 2 phases of a 110VAC 3 phase supply. I had a start capactior fail in this unit. When I connected the replacement unit, the compressor failed to kick on however it started when bumped with my fist. After kicking off however, the compressor would not always kick back on when required.
So... Since the power supply I'm using to "mimic" a single phase 230VAC supply is ACTUALLY a 2 phase 110VAC (2 of 3 phases) ie. not 180° opposed but 120° then 240°, does this mean that with regard to starting capacitors, polarity becomes an issue?
I am aware that the resultant voltage is 208VAC, however the original unit has run on this supply for a number of years without issue.
Thanks for any insight.
