Summary

COSEL Power Supply, Noise Filter 2025 Product Catalog

AC-DC Power Supplies Medical TypeInstruction Manual!Even a slight difference in output voltage can affect the balancebetween the values of I1 and I2.Please make sure that the value of I3 does not exceed the ratedcurrent of a power supply.I3 [ the rated current valueBad exampleGood exampleFig.1.2. Example of measuring output ripple and ripple noise1.8 Isolation!For a receiving inspection, such as Hi-Pot test, gradually increase(decrease) the voltage for the start (shut down). Avoid using Hi-Pot tester with the timer because it may generate voltage a fewtimes higher than the applied voltage, at ON/OFF of a timer.1.9 Reducing standby power!As for option -R2, reducing standby power is possible by OFF signalof the remote control.Please refer to instruction manual 6.1.2 Series Operation andParallel Operation2.1 Series Operation!You can use a power supply in series operation. The output currentin series operation should be lower than the rated current of apower supply with the lowest rated surrent among power suppliesthat are serially connected. Please make sure that no surrent exceedingthe rated current fl ows into a power supply.Power +Supply -Power +Supply -LoadPower +Supply -Power +Supply -Fig.2.1 Examples of connecting in series operation2.2 Parallel Operation!Parallel operation is not possible.!Redundancy operation is available by wiring as shown below.PowerSupplyPowerSupply+-+-I1I2I3LoadLoadLoad3 TemperatureMeasurement Point!Environment to use it and Installation environmentWhen using it,it is necessary to radiate heat by the heat of the powersupply.Table 3.1 - 3.4 shows the relation between the upper limit temperature(Point A and Point B) and load factors.Please consider the ventilation so that the convection which isenough for the whole power supply is provided.And temperature of Point A and Point B please become lower thanupper limit temperature.The life expectancy in the upper bound temperature (Point A andPoint B) is three years or more.Please refer to External View for the position of Point A and Point B.In case of with Chassis and Cover, please contact our sales officefor getting more information.Remarks:*Please be careful of electric shock or earth leakage in case oftemperature measurement, because Point A and Point B is livepotential.*Please refer to 4 if you want to extend the longevity of the lifeexpectancy.Table 3.1 Temperatures of Point A, Point B LMA100F-24-YMounting CoolingMax temperatureLoad factorMethod MethodPoint A[C] Point B[C]75%
