MR78 operating temperature

sedat-pamay — Thu, 22 Feb 2024 06:07:24 GMT

Hello All ,

According to Datasheet of MR78 , operating temperature: -4 °F to 131 °F (-20 °C to 55 °C) .

I will use MR78 in temperatures of -18/-19 °C. However, since -19 °C was very close to the minimum operating temperature, I am not sure that it can work well for a long time.

Has anyone tested the AP at these temperatures for a long time? Can I use it at these temperatures for a long time without any problems?

Regards

@sedat-pamay the device will usually operate outside of the datasheet parameters, but as long as you are within them then you will be fully supported and should expect good reliability.

I don't know the answer.

A simple solution might be to put the AP into an ABS electrical box and put a small light into it (not LED). The light will generate a small amount of heat, and might just light the temperature a couple of degrees in a small confined space.

Hi , Thanks for your reply ,

I thought the same way, but the temperatures will be at the limit and this may not be good for the device life in the long term. So we I will to change the mounting place and move forward with the MR76 model for a guaranteed solution.

Hi ,

Thanks for your answer,

This is good idea , ı can use it other projects 🙂

But unfortunately I cannot use this solution due to some installation restrictions.

I am continue with MR76 models AP becasue of its wider temperature ranges.
