Technical FAQs 4

What is a parallel power supply?

Parallel power supplies refer to a configuration where multiple DC power supplies are connected in parallel to increase total output current. Each power supply shares the current load, ensuring that no single unit is overloaded. Higher Current Output – Allows for increased power delivery by combining the output of multiple units.

What is a parallel power supply topology?

Parallel power supply topologies have two or more power supplies configured to provide output power to the same system.

How many power supplies can be connected in parallel?

Up to 64 EA-10000 series power supplies and loads can be connected in parallel via the master-auxiliary bus. The system can consist of any combination of units of different power classes within the same EA-XXX family (EA-PSB, EA-PSI, EA-ELR etc.).

Why do power supplies need to be loaded in parallel?

As a single unit is not sufficient to provide desired power needs, two or more power supplies in parallel are expected to be always loaded. The control circuit responsibility shifts here to balancing the load sharing among the connected power supplies equally as possible.
