24 VDC (Nom.), 2 A, -10 to +60°C Operating Temperature, Power Supply General Specifications Global Approvals: CE (LVD and EMC) — LVD IEC60950; Immunity, Emissions and Transients — EN61000-6-1, EN61000-6-2, EN61000-4-2, EN61000-4-4, EN61000-4-5. Temperature Range: –10°C to 60°C Low Noise Outputs: Well regulated, ≤2% tolerance 20-50 mV ripple. Internal/External Protection: Overvoltage, overload, short circuit protection, immunity and transient protection to stringent CE levels. General Specifications (Continued) Wide Input and Output Selection: Including 3 phase and single phase inputs, and 5 V-48 V outputs. Easy Installation Connections: SDN and SFL24-24 Series screw terminals, SFL pluggable connectors (mating connector included). Switching Technology: Very compact, highly efficient, hold up time; single phase — 20 ms; 3 phase — >11 ms. Extra Reserve Boost Capacity: On SDN models for continuous regulated start-up of inductive, switching or high in-rush loads. With the addition of an external redundancy module the SDN series 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. All models ending in P also include a DC OK status relay contact. SDN2.5-20RED and SDN30/40RED 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. Refer to the chart below for information on which module can be used for each SDN power supply. Power Rating — A yes or no indication references if the module can or cannot handle the power rating of that power supply. Input/Output Signals — Yes indicates that the supply would have an independent relay contact to provide power supply status, and the DC bus output from the redundant module has it's own DC OK relay contact. Output only indicates that only the output of the redundant module would have a DC OK relay contact. Features
