COSEL Power Supply, Noise Filter 2025 Product Catalog

AC-DC Power Supplies Enclosed TypeInstruction Manual5.2 Isolation!When Hi-Pot test is conducted for the inspection, gradually increasethe voltage and decrease the voltage gradually by using adial. Please avoid a Hi-Pot tester with a timer because when thetimer is turned ON or OFF, it may generate a voltage a few timeshigher than the applied voltage.!When a unit is tested for isolation between input and output, inputand FG or output and FG, short the output to all function terminals.5.3 Auxiliary Power (AUX)!The unit has the auxiliary power (AUX:12V0.1A) in CN3 to providefor the remote ON/OFF and external circuits.!AUX circuit(AUX,AUXG) is isolated from input ,output,FG,andfunction terminals except RC1.!If the output current of Aux exceed 0.1A, the unit might be damagedor malfunction.When a DC-DC converter is connected to AUX, the current mightbe severalfold of normal current when starting up. Please checkthe current.!The maximum capacitor to AUX 22μF.The output voltage can be adjusted from 5V to 12V by the communicationfunction. (Refer to item 2.11)5.4 Variable Speed Fan!The power supply has built-in variable speed fan. The fan speedvaries depending on load and ambient temperature.5.5 Medical Isolation Grade!PCA series fi t 2MOPP2MOPP6 Options6.1 Outline of Options* Please inquire us for details of specifi cations.? -C!Except a certain (e.g.terminal, potentionmeter), PCB is coated.? -G!This power supply is low leakage current type.!Differences from standard versions are summarized in Table 6.1.? -TTable 6.1 Low leakage current typeLeakage Current(AC240V)0.15mA maxConducted NoiseN/AOutput Ripple Noise150% of standard units!Option -T models have a terminal block instead of an output busbar. (Excluding PCA1500F)!This option is available for the following models.-All models of PCA300F.-PCA600F-12, -15, -24, -32, -48-PCA1000F-24, -32, -48!When wiring the load wire, select the wire in consideration of theheat generation so that the temperature of points B in Fig. 6.3 islower than the temperature specifi ed in Table 6.2 - Table 6.4.Please note that if the wire is thin, the wiring heats up, heat istransferred to the inside of the power supply, and the power supplymay malfunction.Please use within“Derating”.1MOPPPrimary SecondaryTable 6.2 Ambient temperature and specified temperature of point B (PCA300F)Temperature of point BAmbientModeltemperatureVin=85 - 264VACVin=88 - 370VDC-5 Ta≦40C 60CSafety GNDFig.5.2 Medical Isolation Grade6.5 External Component (EMI/EMC Filter)?
