AC-DC Power Supplies Enclosed TypeInstruction Manual3 Life Expectancy andWarranty3.1 Life Expectancy!Expected Life is 10 years based on the cooling condition“Assemblingand Installation Method”3.2 Warranty!Warranty is 3 years.4 Others4.1 Output Voltage Monitor!Output voltage monitor (+M, -M) is available for use(SCHA10000T : CN9,10, SCDA10000T : CN7,8) .Connector locations and pin assignment are shown on the externalview.!Fig.4.1 shows the internal circuit of monitor (+M, -M) terminal.!Not allow to draw output current from +M, -M.4.2 Output Current Monitor!You can monitor an output current by measuring a voltage betweenthe terminal CTB (SCHA10000T : CN5,6, SCDA10000T :CN3,4) and -V (COM).Connector locations and pin assignment are shown on the externalview.!Fig.4.2 shows the relationship between the voltage of the terminalCTB and the load factor.The output current shown in Fig.4.2 should be used only as aguide.R1R2C1C2+VFig.4.1 Internal circuit of output voltage monitor-V+M-MR1,R2: 10kWC1,C2: 0.1μFVoltage of CTB [V]10864200 20 40 60 80 100Load factor [%]LoadOutput currentFactor = Rated currentFig.4.2 Load factor conversion graphNote :! Careful wire connection is needed to avoid a malfunction causedby noise.! Use a measuring instrument which has 500kΩinput impedance ormore.! Do not short between CTB and -V (COM) because of possibilityof failure.4.3 External output voltage control function/Constant current regulation!The power supplies have an external output voltage control function.The output voltage can be adjusted by applying external voltagebetween the terminal SLV and COM.The calculation formula is 1 as following.Output Voltage = (The voltage between SLV and COM)×10 [V]................................. 1Table 4.1 Outout voltage adjustment rangeModelOutput voltage adjustment range [V]W/O option“-Y1”35.0 - 52.8W/ option“-Y1”approximately 0 - 58.8!Negative voltage to SLV terminal may cause failure.!There is more than one method to adjust the output voltage, includingthe methods to use external resistors and external powersupplies. Since each method has different characteristic, pleasecontact us for details.!SC series can be used as a constant current power supply byusing output current monitor function and external output voltagecontrol function.To use the SC series as a constant current power supply, the externalcontrol circuit is necessary. Please contact us for details ofexternal circuit.To use SC series as a constant current power supply, it is necessaryto order Option-Y1 model.SC-16
