Mikrotik Support told me: you have to use 24V.
I am powering older Mikrotik gear (like CCR 1036 8G-2S+ routers ) with a 24V setup using these:
- "Meanwell PSC-160B-C"
This is a 160W Single Output Power Supply with Battery Charger (UPS Function), with two 12Ah 12V (serially connected) batteries.
It works for us without problems, for years...
Now... I was planning to use this setup for the CRS317-1G-16S+ when I stumbled across this thread.
The aforementioned Meanwell PSC-160B-C device's output voltage ranges from 21V up to 27.8V (21V is the cut off voltage to protect the battery, the 27.8V is the highest charging voltage)
As I mentioned all of the older Mikrotik devices are working flawlessly with this Meanwell power supply (CCR 1036, CCR 1009, CSS 326, CRS 326...)
Am I good to go with this setup on the CRS317-1G-16S+ also, or this device CAN NOT take voltage higher than 24V...?
