greenhouse climate controller voltage help

[Shoei]

Interesting piece of kit, it looks as though they are manufactured for 120 or 240V, so the US version would need a transformer. The outputs seem to be switched from the input voltage so the loads (lighting, heat etc) also would need to run off 120V so the supply transformer would have to be sized to cope. 240V loads could be used using relays or with additional transformers but it could all get a bit clunky.

The US version is unlikely to be legal in Europe, it would need a CE label and I can't see one in the pictures. It's your call whether that matters to you but you should know about it to make an informed choice.

ok thank you for the advice..

I do know of a person who used the previous version of the unit and ran it from a uk power source with no issues. and it says the same thing in the specs, 120v -240v . and I don't know why they would say its usable on a power supply of 240v if its not safe.
but im always very safety conscious so don't like taking risks with things.

as for legality, I suppose its just because we have euro standards that cover our safety, the usa has their own system I would think.

The supply range isn't clear, it says 120V on the label but it might work fine on 240V. I'd want to know what was inside the box before relying on it.

The standards are worth bearing in mind because if you buy one direct from the US you have personal liability for CE compliance, as the importer. Unlikely to be an issue but it's worth knowing where you stand.

nice to see some common sense posting from a new member. makes a change from the usual " how do i wire my shed". .

hi, I am looking to buy a greenhouse controller from the usa as I run a small commercial plant nursery. unfortunately a good unit is hard to source in the uk.

my question, can I use this from a regular uk power supply?
