4.3. Thermal Data
The main heat contributors are:
1.
The electronic devices of the
eGrabber Frame Grabber
including the losses of the power
converters of the
main
power distribution network.
2.
The losses of the 12V-24 V power converter of the
auxiliary
power distribution network of PCI
Express
eGrabber Frame Grabbers
. The actual contribution depends on the effectively
delivered PoCXP power!
NOTE
The losses of the 12V-24 V power converter are estimated with 17 W* of
PoCXP output power per connector and a worst case 24 V DC/DC converter
efficiency of 92.5%.
(*) 25 W for
3621 Coaxlink Mono CXP-12
and
3621-LH Coaxlink Mono CXP-
12 LH
Generated heat power estimation and cooling method
The following table shows the estimated heat power generated by the card for two use cases:
1.
Heat power 1:
when the card doesn't deliver any PoCXP power
2.
Heat power 2:
when the card delivers the maximum PoCXP power on all connectors.
