Hello,
I was wondering what the temperature derating is for the Orion Tr dc dc converters. We are running 3 in parallel. The control box may get to 50 degrees Celsius. Thanks.

What is the output derating for a Orion tr 48/24-16 at 50 degrees Celsius?
There is some temperature derating information for the Orion's available in their data sheet.
Though this only includes a 25 and 40 degree rating.
You can also use the information in the Victron ToolKit App. This allows you to expand the temperature range for the inverters and chargers. The Orion will behave very similarly.
In this case, there is 60% of the nominal output rating at 50 degrees compared to 25 degrees.
It's important to note that as ambient temperatures get very high, and with little airflow, the device is unable to effectively cool itself down with its heat sink.
You may wish to consider using an IP67 rated unit and give it fresh air so that it can dissipate the heat better.
