Ericsson MINI-LINK is a wide range of equipment in different possible configurations.
What are you planning to use?
Max power dissipation allowed through the PFU when running an AMM 20p, is 1200 Watts.
But this is rarely accomplished.
All depending on what MMU units and RAU units etc you are using.
Latest release will also have a DC-bypass with right plugin units. This feature will save power by turning off DC/DC conversion for certain configurations.
