Summary

COSEL Power Supply, Noise Filter 2025 Product Catalog

AC-DC Power Supplies Medical TypeInstruction Manual-Do not exceed the current rating , it may causes malfunction orfailure of the internal circuitry.Table 6.1 External capacity on the output recommended capacity of AUX2Output VoltageRecommendedcapacitance [μF]5V (AUX2)0 to 330Remarks:When the load currnet changes rapidly, for output stability improvement.Please contact us for details.!Remote ON/OFF-You can operate the remote ON/OFF function by sendingsignals to CN601. Please see Table 6.2 for specificationsand Fig.6.2 for connecting examples.-Remote ON/OFF circuits (RC and RCG) are isolated from input,output FG and AUX.-Please note the following when using the remote ON/OFF function.1 Turns on by drawing current to RC.2 The current flown to RC is a 5mA typ (maximum 25mA).3 If the output voltage is turned off through the remote ON/OFFcircuit, 12V AUX stops.4 If voltage or current of a value not listed in Table 6.2 is appliedbetween RC and RCG, the output voltage may not be generatednormally.5 Please wire carefully. If you wire wrongly, the internal componentsof a unit may be damaged.Table 6.2 Specifi cations of remote ON/OFFFig.6.2 RC circuit example ?R3Output on SW close (3mA min)SW LogicOutput off SW open (0.1mA max)Optional harnessH-SN-38(a)5V7780W 12AUX2RCR1 V1SWRCG8 AUX2GCN601(Example V1 : 15V R1 : 2kW)(b)5VFig.6.2 RC circuit example7780W 1AUX2RC2 RCGSW8 AUX2GCN601* If the output of an external power supply is within the range of4.5 - 12.5V, you do not need a current limiting resistor R1. Ifthe output exceeds 12.5V, however, please connect the currentlimiting resistor R1.!To calculate a current limiting resistance value, please use the followingequation.R1 Recommended resister [W]V1 - (1.1 + Ri×0.005)0.0056.2 Medical Isolation Grade!GMA series fi t 2MOPP1MOPP2MOPPprimary secondary1MOPPFig.6.3 Medical Isolation GradeRi : 780[W]6.3 External capcitor on the output sideSafety GND!When the load currnet changes rapidly, for output stability improvementwe recommend that you connect the capacitor to theoutput terminal.Tabel 6.3 External capacity on the output recommended capacity [μF]ModelOutput voltage [V]Recommendedcapacitance [μF]GMA300F-1211.4[Vo[13.20 to 15,000GMA300F-2422.8[Vo[26.40 to 8,800GMA300F-4845.6[Vo[52.80 to 220GMA300F-5652.0[Vo[56.00 to 120Remarks:When load current changes rapidly, some specifications may notmeet the spec.Please mount power supply after enough evaluation and complywith recommended amount of capacitors. If you exceed the ratedamount of capacitor, output for power supply may be stopped orpower supply may be unstable.6.4 Others!High voltage exists in the power supply for a few minutes afterinput voltage is stopped. Please pay attention to this during maintenance.!This power supply is manufactured by SMD technology. Thestress to PCB like twisting or bending causes the defect of theunit, so handle the unit with care.-Notes for mounting1All Mounting holes should be tight and secured.2 Power supply should be mounted parallel to the mounting surface.3Avoid applying mechanical stress or shock to the power supply.!When power supply is energized or immediately after power supplystops working, power supply is still very hot, so please handleit with care.GMA-10
