WS-6-MINI Board Temps
Posted: Tue Jun 09, 2015 4:15 pm
We have been using the WS-12-250A units for some time now, and have recently received our first shipment of WS-6-MINI devices. While testing the WS-6-MINI we noted the temperatures seemed alarmingly high.
As an example we are using a WS-12-250A RevB to power equipment on our test bench. We are using ~108W as being reported by the unit, both fans are 0 RPM and temps are 31C/58C/58C (Board/CPU/PHY). Ambient temp is 20C (taken from Tycon Web Power Ext Probe).
The WS-6-Mini we are testing is reporting power usage of 21.4W which is about half the equipment we plan of connecting to it. The temps on the WS-6-MINI are 64C/91C/93C (Board/CPU/PHY) and this in not enclosed, it is sitting free and clear on our bench. We put it inside the outdoor enclosure we have for it and the temps increased to 74C/102C/104C (Board/CPU/PHY). This has us very concerned.
When my company preforms temperature testing we use a hot box heated to our test temperature (usually 45-50C). The hot box has no venting, and no air flow. We would then power the equipment on and run testing on the equipment simulating a stressful max heat output scenario. I am kinda afraid to do this to the WS-6-MINI.
Are the temps we are seeing on the WS-6-MINI accurate? Is your testing for the operating temperature range similar or different to what we do?
Finally, I think it would be really nice to know what the max operating temps for the Board/CPU/PHY would be for all the Netonix models as reported from the units themselves. This way if I log into a remote unit and see a CPU temp of 104C but I know it can operate up to 120C then I do not have to worry.
Cheers
