If you can get the machine in 240V three phase, then a VFD in a small enclosure that takes 120V input and outputs 240V three phase is pretty easy to configure. I don¡¯t know what the HP of these units are, but the VFD¡¯s with 120V input might go up to 2hp or so, plenty of them at 1hp, so you would have to look around.

Greetings!?
I had considered posting this in the Mafell forum, but I suspect there's a little more electrical aptitude here. I've been using a Mafell ERIKA 70 for several years now for my on-site work, and I just can't say enough good things about it. For those not familiar with the machines, this video gives a brief overview of pull-push saws:??They are sort of like a portable sliding saw, with the option to either rip or crosscut depending on how you configure it. Changing configurations only takes a couple seconds, and for crosscutting I've found it far more accurate than a miter saw.?
While I am trying to perform more work in my Shop, I think I am destined to spend a sizable portion of my career performing work on-site, so having a good portable solution is important.?
Anyways, with the recent minor facelift of the Erika line, Mafell has discontinued the 120V option on the Erika 70, leaving all of the Erika models now in only 240V. I believe that the machines destined for the NA market are 240V 60Hz, "stock" machines are 240V 50Hz. So, I'm going to jealously guard my 120V Erika 70, but I can see the writing on the walls, and was wondering what my options might be in the future should I either:
?1. Need to replace my Erika 70 120V with a Erika 70 or 85 240V 60Hz, or:
2. Acquire a Erika 60 240V 50Hz for those small jobs where the 70/85 is overkill
My requirements are:
-- Need to be able to work on-site in residential settings, with access only to 120V 60hz power. Needs to supply 240V 60Hz (50Hz would be nice for the Erika 60), the Erika 85 draws 2,500 watts, the Erika 60 draws 1,300 watts
-- Needs to be a portable solution (preferably <40 lbs)
-- Needs to be a solution that is weather tolerant (needs to be able to handle snow, drizzle, heat, cold, etc.....)
I suppose the simplest solution would be something like the Festool Sys-Powerstation??, but I wonder if there are portable step-up transformers or "hardened" VFD solutions? In terms of the Festool Sys-Powerstation, I wonder if anybody would be willing to work with me to get a 240V model imported to NA (please message me privately for this). Or, am I simply out of luck and need to start going with the flow, reverting back to a miter saw and table saw (say it ain't so!!)??
Anyways, I know there's a lot of creativity here, and would be curious what thoughts folks might have. Thank you in advance for any tips or advice.....?
