Hello,
I bought a PID controller of dubious quality. EBAY posting said 110V to 240V but the device itself says 220V AC input voltage.
I got my money back, but it is just sitting there now so I would still like to use it.
Would there be any problems if I run 120V AC through it instead? I'm primarily concerned if it is going to be unsafe, but perhaps there could be performance issues related to it as well.
Thanks

 

From the information you have provided, I can tell you with certainty, nothing.

How about a link to the item or at least a picture showing all markings.

PID controller for what?
Servo?
Thermal?
Max.

 

Thermal PID
It is this one
100-240VAC PID REX-C100 Temperature Controller SSR-40A Thermocouple Heat Sink | eBay
It claims to be 100-240VAC but the side of the unit as well as the instruction manual says 220VAC

My question is more general though...I would still like to wire it up with 120VAC since it is all I have. Are there any safety downsides to this? If so, I won't attempt it.

 

Hook it up and try, there should not be any more safety issues that on 240v.
Max.

 

Indeed there should not be any safety issues, but it may have performance issues. More description of the device will certainly increase the probability of getting some useful responses.

 

Here is the manual, says 100v - 240v input supply ,
