An Amazon purchaser of your converter model 090047 reported that it did not work below -20C. Your specification is -40C. I want to use several these converters to power 5V security cameras in Canada so they must work down to about -25C. Will they work?
The operating temperature should be -20℃ to 80 ℃. Now the seller is Amazon company, we think they may make some mistakes on product description. We pass it on to Amazon.
