Hi all, I saw this on an old thread:
The compressor is 115V 60Hz with 4.5A running current, and according to the nameplate, 26A locked rotor current. Domestic supply here is 240V 50Hz. In vain I tried to power this via a 12VDC car-style 800W inverter but, as expected, the inverter cut out when the compressor kicked in.
So I'm considering powering this unit via a single-phase VFD. I'm looking at the Invertek Optidrive ODE-2-22110-1KB42-01 (10.5A rated) or ODE-2-12075-1KB12-01 (7A rated) (http://www.invertekdrives.com/varia.../model-data/datasheet.aspx?mID=ODE-2-12075-1K), both are 185% current rated for 2s. I would consider rewiring the AC so that the compressor and fan are always on in order to make use of the soft-start capabilities of the VFD, but I'm not sure that this will actually work.
Can anyone advise? Will this work, or be even vaguely efficient?
This is pretty much what I'm trying to do. I have a cheap 500W 115V 60Hz window air conditioner (Frigidaire FRA054XT7), which is wired with the fan+compressor running off the same run cap, no start cap:Is the purpose of the inverter to operate a 60Hz motor from a 50Hz line?
