Power Supplies 3 SDN Series Redundant Options The SDN Series standard options allow for operation in a wide variety of applications. With the addition of an external redundancy module, the SDN can also be used for true redundant operation including 2N and N+x configurations. All SDN units include built in current sharing for parallel and redundant operation. The external modules SDN 2.5-20RED and SDN 30/40RED increase the reliability by isolating the supplies and adding more signal options. Paralleling for increased power does not require the use of these modules. Module Compatibility Two separate modules are available to provide the maximum flexibility in size, cost and signaling capability. Refer to the chart below for information on which module can be used for each SDN power supply. Power Rating A simple Yes or No indication that this module Features can or cannot handle the power rating of that power supply. DC OK Relay Contact Input/Output Signals Yes indicates that each power supply True Isolation would have an independent relay contact to provide power High availability supply status, and the DC bus output from the redundant SDN features and quality module has its own DC OK relay contact. Output only indicates that only the output of the redundant module would have a DC OK relay contact.

Power Supplies 3 SDN Redundant Series Specifications for SDN2.5-20RED and SDN 30/40RED Catalog Number Description SDN 2.5-20RED SDN 30/40RED Concept By means of a separate redundancy module, you can interconnect several identical SDN power supply units in a N+1 redundant mode. These external modules decouple the power supply outputs from each other so that, in case of failure, one power supply unit cannot overload the other units. The modules incorporate DC OK relay contacts. The switch on front of the SDN power supply should be placed in parallel mode (not single mode) when power supplies are used with redundant module.
