This is a two prong approach to a situation I'm looking at for the place I work. Like many industrial/commercial OEM's you have to cater to the single phase end of things as well as 3-phase. I want to get away from single phase motors and stick to 3-phase. No start windings, no capacitors, no extra mechanical bits. In terms of reliability, if I can remove all single phase motors from my shelf (but still cater to the 230V crowd), I will be a happy man.
My question is, is there a "barebones" VFD/Driver on the market that essentially only packs a handful of features:
- Takes in single phase, convert to 3-phase
- Overload Fault Protection
- Handle from 1/2 HP to 5 HP capacities (should just be a heatsink and internal component sizing at that point?)
- Couple of I/O points to allow for Start/Stop/Reverse/OL Fault
- 220V single phase input, 208 3-phase out
- (Optional) EMC Filter built in
- (Optional) Ramp Up/Ramp Down (soft start, no programmable features)
I've been looking for sometime reputable with a ultra-simplified feature list but had no avail. At this point, I'm ready to build one from scratch if that's what needs to be done. I figured if anyone will know it will be you folks here...I've looked through ACTech, ABB, Siemens, Mitsubishi, etc...but no luck. If there isn't anything terribly cost effective on the market, what are we looking at if I wanted to hire someone smarter than myself to help tackle getting one put together?
