Good day all,
I have a new Sedgwick TA315 saw bench with a 3-phase motor, and currently it is running smoothly from a 3-phase supply. I will soon move the saw bench to a residential area, with no access to 3 phase supply.
So I would obviously need to buy a phase converter to run the saw bench from 240V supply, I have read a lot about this topic in the forum and elsewhere, and narrowed my choices to either a rotary phase converter or a digital phase converter.
However, it seems that the digital unit is extremely expensive. I contacted Drives Direct, and they explained that for choosing the right converter I would need to take the Sedgwick motor HP (it is 4HP), times this by 3 to get the starting load (=12 HP) and go for the next size up – 15 HP. The price for this digital phase converter is £4500 - £7400 (!!), depending on the specific model chosen.
My questions are: Does anyone have a Sedgwick TA315 or similar saw bench and encountered the same situation? Is there a good reason to prefer a digital phase converter over a rotary unit (except for the noise problem with the latter)? I must note that in the future I’m going to have an old Wadkin FM planer-thicknesser in my workshop and hopefully a Wadkin RS lathe, so the converter should be able to run all machines (not simultaneously, only one at a time).
Any help would be highly appreciated!
