Hi, friends!
Sorry for my ignorance on the subject. In my city/country, the voltage is 220V / 50 Hz. I am thinking about buying an Inkbird Heating PID Temperature Controller (IPB-16S) to build a RIMS system that, supposedly, has input and output voltaje of AC 100-240V 50/60Hz.
So could I use a 3500W heating element? I have read, I don't know where, that in 120V it only supports 1650W heating elements and if it is 220V it can support up to 5500W. Is it true?

A 20A circuit is about the highest-rated 120V branch circuit you'll find in a typical US house. With no other loads on the circuit, that's a max power draw of 2400W. (20*120=2400)

A 15A circuit on 115V can draw 1725W with no other load on the circuit.

I run a 3500W induction cooktop on a 30A 220V circuit.

That controller will not work on 220V. You must have gotten some bad information from somewhere.
