Discuss Japanese 3 Phase Wiring in the Commercial Electrical Advice area at ElectriciansForums.net
Thanks, I upload some photos of the control box internals on Monday. The control box is powering a small rotating motor on small drilling machine.Update: I misread your 200V as 100V and gave an unhelpful answer.
200V is standard Japanese 3-phase delta. Red - L1, White - L2, Black - L3, Green - earth.
Unless it can be internally re-configured into star and will accept 230V in place of 200, you will need a stepdown transformer from 400V (normal UK 3-phase voltage) to 200V.
What is it for and what is its power rating? Do you have any info from the manufacturers?
