COSEL Power Supply, Noise Filter 2025 Product Catalog

AC-DC Power Supplies Confi gurable TypeInstruction Manual2 Series / Parallel operationin Modular power supply2.1 Series operation(Applying modle : A-C, J-L, E4-G4, E-G, S, T, 2C)!Series operation is available with identical output modules.The copper bar for series connection is assembled before shipping.!The output current in series operation is the same as the one ofthe individual modules that are connected.!Please note the following items,1Only identical modules can be connected in series.2Total of the rated voltage in series has to be 48V or less.Total output voltage should be adjusted within 60V.3 The series operation is not available along with the parallel operation.4 Constant current function is not available.Please contact us for any other conditions.2.2 Parallel operation(Applying module : E4-H4, E-H, S-V, V4, V5, 2C-2M)!Parallel operation is available with identical modules.With parallel operation, the output modules need to be tuned internally,and it cannot be done in the fi eld. The copper bar for paralleloperation is assembled before shipping.!Output current in parallel operation.Current ratings for output modules connected in parallel arederated by 10%.Ex.: AM06-HHCB-0400- Parallel code 04 means slots 3 and 4 are connected in parallel.- The output modules for slot 3 and 4 are“H”, so the ratedoutput current is shown below.Current = (5+5)×0.9=9A!Please note the following for parallel operation.1 The remote sensing is not available along with parallel operation.2 The peak capability is invalid in parallel operation.3 In case that output voltage adjustment is required for modulesconnected in parallel, the modules should be adjusted individually.If precision adjustment is required, remove the copper barbetween modules, adjust the output voltages individually, andrefix the copper bar. The output voltage difference will appear asload regulation. To reduce the regulation, adjust the each outputvoltage to be the same value as possible.4 When the output current changes rapidly such as pulse load,the output voltage fluctuation (dynamic load regulation) mayincrease. Therefore, please consult us the unit will be used forsuch an application.5Specifi cation value of ripple and ripple noise is tripled.6Constant current function is not available.!When in series and parallel, the output voltage at the start-upmight have the step as shown in Fig.2.1.AC Input voltageOutput voltageInput ONFig.2.1 Start-up waveform in series and parallel operation3 Functions3.1 Input voltage range!The input voltage range is from 85 VAC to 264 VAC.The rated input voltage range for the safety approvals is from100VAC to 240VAC (50/60Hz).!If the input voltage was out of the above range, the power supplymight not meet the specifi cation or might fail.Please do not apply the square wave of the UPS, the inverter andso on to the power supply.!When DC input is required, please contact us.3.2 Inrush current limiting!If the switch is installed on the input, please select the one whichcan work at the inrush current.!The relay is used in the inrush current limiting circuit. If the intervalof the input on/off was short, the inrush current limiting might notwork correctly. So, please make its interval long enough.And, it makes the primary and the secondary inrush current.3.3 Overcurrent protection!The unit has the overcurrent protection which will activate at 105%of the rated current, 101% of the peak current or more. The outputwill automatically recover when the overcurrent condition is resolved.Please do not use the unit with short circuit and/or under the overcurrentcondition.!Hiccup modeWhen the overcurrent protection activates and the output voltagedrops, the output will get intermittent to reduce the average current.The over current protection of the module R is not hiccupe mode.3.4 Peak current protection(Applying module : G4, G, H4, H, U, 2C, 2D, 2M)!The unit has the peak current protection. (Refer to the item 4 forthe detail.)When the peak current protection activates, the output stops.After a few seconds, the output will recover automatically. However,it will stop again if the overcurrent condition was not resolved.* The recovery time depends on the input voltage and the loadcondition.AME-15
