The specs for the PID alimentation are:
12V - 24V (AC/DC) +/-20% 3VA Polarity not required
I suppose I can add a small transformer like this one 110V to 12V 60W Electronic Transformer Halogen Light Power Supply Converter #Z (ebay , 3$) , it's AC.
It will be better to have a 110 volts , but the PID is in UPS hands and I don't want to send it back from Canada
