COSEL Power Supply, Noise Filter 2025 Product Catalog
AC-DC Power Supplies DIN Rail TypeInstruction Manual1.8 Low Power Consumption■These power supplies are designed for low power consumptionat no load.■When the load factor is low (Io:0-20%typ), the switching powerloss is reduced by burst operation, which will cause ripple andripple noise to go beyond the specifications.■Ripple noise during burst operation will change depending onthe input voltage and the output current. Consult us for adviceon how to reduce ripple noise.■When there is a need to measure the stand-by power consumption,measure it by using the average mode of the tester. The measuring environmentmay influence the result. Consult us for more details.2 Parallel Operation■Redundant operation is possible by wiring as shown below.PowerSupplyPowerSupplyFig.2.1 Example of redundancy operation■Even a slight difference in output voltage can affect the balancebetween the values of I1 and I2.Make sure the value of I3 does not exceed the rated output currentof the power supply.I3 ? the rated current value■Parallel operation is not possible.+-+-I1I2I3Load3 TemperatureMeasurement Point■Ambient temperature indicates the temperature of the inlet of theair.4 Life Expectancy andwarranty■WarrantyTable 4.1 WarrantyWarranty [years]Cooling Average ambientLoad factor Load factormethod temperatureIo[75% 75%
