COSEL Power Supply, Noise Filter 2025 Product Catalog

AC-DC Power Supplies Enclosed TypeInstruction ManualThe current has to be more over normal operation current even ifone power supply fails.Maximum output current [ Rated current per unit X Numbers ofnormal operated units X 0.95!If you add one extra power supply in parallel operation, even ifone of the power supplies in your system fails, the remaining nonfailedpower supplies continue to sustain the system. If one of thepower supplies stops operating, the output voltage may changeabout 5%.!Parallel with other products is not allowed.!Please shut off the input voltage when you replace a failed powersupply.!After replacement, please make sure that all wirings are completedcorrectly, before re-applying input voltage.!Hot-swap or Hot-plug is not available.!2 or more power supplies failures may cause the output voltage todecrease, lending the application system to shut down. Immediatereplacement is recommended when a power supply has failed.Power supplyPower supplyPower supply+VVBCBCOM-V+VVBCBCOM-V+VVBCBCOM-VLoadFig.2.3 Example of N+1 redundancy operating connection!During N+1 redundancy operation, do not connect the TRM terminal.!If you have any questions about series, parallel and N+1 redundancyoperations, please contact us.3 Life Expectancy andWarranty?
