COSEL Power Supply, Noise Filter 2025 Product Catalog

AC-DC Power Supplies Bus Converter . Power Module TypeInstruction Manual1 Standard ConnectionMethod1.1 Standard connection method!To use DPG Series, connection shown in Fig.1.1 and outside attachedcomponents are required. Through this connection, DCoutput voltage can be obtained from AC input voltage.AC input voltage and DC output voltage are not insulated.No. Symbol1.2 External componentsF1F2C1F1AC INF1F2C1C2C3C4R1NoiseFilterFGFig.1.1 Standard connection methodComponentInput fuseDPG seriesRAC1 +VOUTC1AC2Output fuseInput capacitorOutput capacitorTable 1.1 External componentsHoldup capacitorY-capacitorInrush cuurentprotection resistor-VOUTAUXENAFGHeatsinkR1TH1F2C2 C3R2C4PC1LF1Required characteristicsDBS/DHS series+VINC5-VINRC115A or lessSlow-blow type10A or lessNormal-blow type2 F or more, Rated ripple current : 59A or more,Film capacitor, Safety approved type1 F or more, Rated ripple current : 48A or more,Film capacitor220 - 2200 FAluminum electrolytic capacitor2200pFSafety approved type4.7 - 22Wirewound Resistor with Thermal Cut-OffsInput fuse : 15A or lessFuse is not built-in at input side. In order to secure the safety,use the slow-blow type fuse F1 (15A or less).Output fuse : 10A or lessSince over current protection is not built-in, use the normalblowtype fuse F2 (10A or less) at output side to secure thesafety.Input capacitor : 2mF or moreInstall an external capacitor C1 (2mF or more) to keep stableoperation and to avoid failure. Use AC250V rated voltage withsafety approved and over 5A rated ripple current.C2 Output capacitor : 1mF or moreInstall an external capacitor C2 (1mF or more) as close aspossible to the output pins to keep stable operation and toavoid failure. Use DC400V or higher rated voltage and over4A rated ripple current capacitor.If the ambient temperature is below -20C, Holdup capacitorsESR increases remarkably.C2 must connect 4mF or more.C3 Holdup capacitor : 220-2200mFSince holdup capacitor is not built-in, install electrolyticcapacitor C3 (220 - 2200mF) close to the ouput pins. Therated ripple current of C3 and the holdup time for moduleshould be considered. The capacitor value should be within220 to 2200mF to avoid failure.If the ambient temperature is below -20C, Holdup capacitorsESR increases remarkably.Therefore, be sure to verify characteristics by actualevaluation.C4 Y-capacitor : 2200pFInstall an external capacitor C4 (2200pF) to keep stableoperation. Use AC250V rated voltage with safety approvedcapacitor.R1 Inrush current protection resistor : 4.7 - 22WConnect a resistor between R pin and +Vout pin for inrushcurrent protection. The surge capacity is required for R1,please contact component mfg. Wirewound resistor withthermal cut-offs type is required.1.3 Wiring input pin!A noise fi lter is not built in this power supply. Connect an externalnoise fi lter to reduce the conducted noise to the power supply line.!A fuse to protect input is not built in. To assure safety, install aslow-blow fuse of 15A maximum to the input circuit F1.1.4 Connection of loaded circuit!For connecting the DBS/DHS series, see Fig.1.1.For details of F2, LF1 and C5, refer to the instruction manual forthe DBS/DHS series.LF1 may not be required, depending on the noise standard or thedesign of the printed circuit board. In this case, ENA and RC1canbe directly connected, without having PC1.!Control load current so that it may flow only when the terminalENA is at "L" . At "H" when inrush current protection circuit is notreleased, excessive current may be applied to the circuit.!For connection of loads except the series DBS/DHS, pleasecontact Cosel development department.DPG-8
