I'm currently researching the possibility of picking up a used KR150 with KRC1 electronics that I am told is in good working order. So far I have been able to find satisfactory solutions and advice when it comes to transportation, training and even offline programming, but there is one lingering question that I am having some trouble finding an answer to - how to supply power to this beast.
The specifications I have received state that I need a 3x400V to 3x415V (+/-10%) supply capable of supplying a rated connected load of 4kVA (some say 4.7kVA). Unfortunately, I am not much of a mains electrician and am not feeling confident that I am going to be able to achieve this requirement.
The shop that I would want to put this robot into has a 240V line, probably single phase, which appears to have a 20A fuse at the breaker box. From what I've gleaned so far, to have the local power company drop a new three phase 400V line would cost me a fortune - far more than I plan on spending on the robot itself and the software I intend to use.
I'm looking into the possibility of using a phase converter to get the 3 phase 400V power I need, but I am running into some barriers of communication when I try to get advice from the friends I have in industrial shops. I am finding that phase converters are rated in HP, but the specs I have for the robot use kVA, and some of my local friends are completely flummoxed that I am not talking about just A.
Could someone point me to some solid info about setting up a KR150 (or similar) robot in a non-heavy industry shop? We're a small, specialty fab shop specializing in unconventional high-tech solutions for creative professionals, like responsive environments, interactive video walls, kinetic sculptures and so on, which is to say that we are not able to put up the $10k's+ that a traditional large-scale industrial shop would have. Creative (but safe!) solutions are very welcome
