AC-DC Power Supplies Enclosed TypeInstruction ManualFor PCA1500F-24, -32, -48* The ambient temperature 40C to 70C should not be morethan the calculated value by linear interpolation. (at Vin=85 -170VAC)* The ambient temperature 50C to 70C should not be morethan the calculated value by linear interpolation. (at Vin=170 -264VAC)!The above specifi cation does not change installation method.Point AFig. 1.1 PCA300F to PCA1000FTemperature measurement pointPoint AFig. 1.2 PCA1500FTemperature measurement pointA thin electric wire could heat up and affect the power supply.Please also use within the“Derating”.1.3 Output side attaching externally capacitance!Depending on the capacitance of the external capacitor, resonancemay occur due to ESR, ESL, and wiring inductance, soplease be careful of ripple increase.! If the capacitance of the external capacitor is too large, the outputvoltage may not rise.! Please do not connect the external capacitor during operations.Table 1.5 Connectable External capacitor on the output side [mF]ModelPCA300FPCA1000FOutput voltage[V]PCA600FPCA1500F50 - 110,0000 - 220,000120 - 34,0000 - 68,000150 - 34,0000 - 68,000240 - 34,0000 - 68,000320 -7,5000 - 15,000480 -3,4000 -7,5001.4 Connection to pulse load!When connecting a pulse load to the PCA series, connect acapacitor Co between +Vout and -Vout.!The thermometry point is conductive. Please be careful of electricshocks.!Output ripple noise may be influenced by measurementenvironment,measuring method Fig.1.3 is recommended.!Output ripple and ripple noise is the value measured by themethod shown in Fig.1.3.* The operation of the power supply might stop due to the internalprotection or its life expectancy might get shorter under the followingconditions.1With pulse load and without the external capacitor.2With pulse load and with remote sensing function.3Depending on the frequency of pulse load.+VoutC1+Load+VoutOutput currentof power supply-VoutOsiloscope /Ripple noise meterBw:20MHz150mmC1 : Aluminum electrolytic capacitor 22μFDifferential probeFig.1.3 Measuring method of Ripple and Ripple NoiseRemarks :When GND cable of probe with fl ux of magnetic force from powersupply are crossing, ripple and ripple noise might not measurecorrectly.Please note the measuring environment.Bad example150mmGood exampleFig.1.4. Example of measuring output ripple and ripple noise-VoutCoPulseloadFig. 1.5 Output side external capacitor connection method!Be careful that the output current of the power supply does notexceed the rated current.2 Functions2.1 Input Voltage Range! Input voltage range of the power supplies is from 85VAC to 264VAC /88VDC to 370VDC (Excluding PCA1000F and PCA1500F).In cases that conform with safety standards, input voltage range is100-240VAC (50/60Hz).!If input value doesn’t fall within above range, a unit may not operatein accordance with specifi cations and/or not start correctly or fail.UPS recommends Sine Wave UPS.Please contact us for square wave input voltage.!The power supply can work at the input voltage dip with the derating.PCA-22
