Tanning beds need buck/boost transformers?

Didn't you still have to buck 240 to 220?

Definitively not. after some calls and double checking, generally speaking things rated '220' or '230' volt will run fine on a nominal 240 system, there was a nice post on here recently on nominal voltages.

Some manufacturers do not want the supply voltage over 230V, on their 220V, equipment, I have a really bad attitude towards 220V equipment being imported here.

That isn't my experience with Wolff tanning beds, but it was in the early 2000's. The manufacturer was very specific that you could not provide 240 volts. The beds required 220 volts period and hooking up to 240 (or 208) would void the warranty.

Good article, but two things regarding this subject. Wolff tanning beds are made in Germany to German standards, so NEMA the first word of which is "national" doesn't apply. Second, when the manufacturer says you MUST apply 220 volts and specifically states you can't provide 208 or 240, then guess what? Are you going to cover the warranty they won't if the bed stops working? Don't get me wrong, I have always questioned whether they are full of stuff, but installed buck/boost transformers anyway.

Well in that case for sure. And older types of lighting (pre electronic) were very sensitive to voltage.
When I am ordering a new service from the POCO here I can request them to 'tap change' up or down by 2.5% or so.
It saves a lot of hassle on a new build to know about odd voltages like this way ahead of time.

It's my understanding that the need for the correct voltage is to get the maximum life out of the lamps in the tanning bed. If you have a salon with 10-15 beds that a lot of lamps to change and they are not cheap.

Yeah, I’ve had people want a buck transformer on their personal tanning bed at home because of that.
