Summary

COSEL Power Supply, Noise Filter 2025 Product Catalog

AC-DC Power Supplies Enclosed TypeInstruction Manual!You can adjust the output voltage in parallel operation by adjustinga potentiometer of just one power supply.To do so, select one power supply as the master unit and turn thepotentiometers of the other (slave) power supplies clockwise tothe end.Once you have done this, you can adjust the output voltage byturning the potentiometer of the master unit.!If you use the remote sensing function in parallel operation, connectparallelly +S and -S of slave power supplies must be connectedto master and connect the sensing wire from the masterunit to the load.!You cannot parallelly operate power supplies with different outputvoltage or electrical power.!If an output stops (through the remote ON/OFF circuit or due toan input shutoff or failure) in parallel operation, the LED of thestopped unit lights off.!When the output current of one unit becomes 10% or less of therated current, the PG signals may turn”High”and the fan maystop.Install H-SN-19Install H-PA-3No.1(Master)V. ADJCN1AC AC( L) ( N) NC FGCN2!Hot-swap or Hot-plug is not available.!If 2 or more units failed, suffi cient power could not be provided tothe system. Therefore, please replace the failed unit immediatelyin case where unit failure is found.!If you have any questions about series, parallel and N+1 redundancyoperations, please contact us.4 TemperatureMeasurement Point!Standard for Cooling?

PBA300F, PBA600F, PBA1000F, PBA1500Fand PBA1500T!You can have N+1 redundancy operation for improved system reliability.!If you add one extra power supply in parallel operation, even ifone of the power supplies in your system fails, the remaining nonfailedpower supplies continue to sustain the system. If one of thepower supplies stops operating, the output voltage may changeabout 5%.!When unit replacement is required due to unit failure, input voltagefor all units must be cut off.!After replacement, please make sure that all wirings are completedcorrectly, before re-applying input voltage.5 Life Expectancy andWarranty!Life ExpectancyPlease see the following tables for life expectancy.?
