Parallel or Series?

In general, when selecting a power supply, it is important to choose one with appropriate voltage and current rating to support the system requirements. Typically, power supplies are connected in parallel to increase the power/current rating and also to increase the system reliability by providing redundancy function. Series connection of power supplies can cater to special needs of the system when requiring higher output voltages.

Delta recommend the use of redundancy modules DRR-20N and DRR-40N for load sharing and redundant operations. To learn more about Delta redundancy modules, please visit Or contact your local sales representative or distributor for product availability.
