Outdoor power supply parallel solution

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.

In principle, it's possible to operate as many power supplies as you need to achieve the desired output current. The simplest is two, providing up to double the current. Principle of parallel PSU operation: The load receives at most the sum of the IMAX of the power supplies selected.

Designers connect power supplies in parallel to obtain a total output current greater than that available from one individual supply as well as to provide redundancy, enhance reliability, avoid PCB thermal issues and boost system efficiency.

While the above is true for many power supplies, EA's 10000 series products allow the user to combine different power levels in parallel. The only requirements are that they must have the same voltage rating, and they must be the same family. Examples are pairing PSB with PSBE or PUB and PSI with PS or PU.

This topology can be successfully implemented but there are many considerations to ensure the efficiency of the configuration. For parallel configurations, power supplies with internal circuits are preferred as the internal circuits will improve the efficiency of the current sharing. If the power

Principle of parallel PSU operation: The load receives at most the sum of the IMAX of the power supplies selected. Use of a protection circuit for parallel operation is actually recommended. The key concern with parallel operation is ensuring each supply contributes equally to the overall current drawn.
