DC-DC Converters POL TypeInstruction Manual3.4 Remote sensing(1) When the remote sensing function is not in use+VOUT+S- SGNDShort at pin rootLOADFig.3.2 Connection when the remort sensing is not in use!When the remote sensing function is not in use, it is necessary toconfi rm that pins are shorted between +S & +VOUT and between-S & GND.!Wire between +S & +VOUT and between -S & GND as short aspossible.Loop wiring should be avoided.This power supply might become unstable by the noise comingfrom poor wiring.(2) When the remote sensing function is in use+VOUT+S-SGNDWire as close as possibleLoadFig.3.3 Connection when the remote sensing is in use!Twisted-pair wire or shield wire should be used for sensing wire.!Thick wire should be used for wiring between the power supplyand a load.Line drop should be less than 0.5V.Voltage between +VOUT and GND should remain within the outputvoltage adjustment range.!If the sensing patterns are short, heavy-current is drawn and thepattern may be damaged.The pattern disconnection can be prevented by installing the protectionparts as close as a load.? -Y1This is change the open loop characteristics accelerated while usingremote sensing with a large external capacitor on the output side.For more information please contact us.3.5 Adjustable voltage range!Output voltage is adjustable by the external resistor.!The temperature coffi ciect could become worse, depending on thetype of a resistor.Resistor ..... Metal fi lm type, coefficient of less than±100ppm/C!When TRM is opened, output voltage is adjusted to the minimum.!R TRM is calculated in the following expressions.RTRM =BRFS30BRFS40/60S/120/150-BRFS60/100-BRDS40/60S/120/150BRDS60/10081214[kW] RTRM =[kW] RTRM =[kW]VOUT-0.8VOUT-0.6VOUT-0.7Table 3.2 Calculation result ofBRFS30Table 3.3 Calculation result ofBRFS40/60S/120/150-BRDS40/60S/120/150NoVOUTR TRMNoVOUTR TRM10.8OPEN10.6OPEN21.040.0kW21.030.0kW31.220.0kW31.220.0kW41.511.429kW41.513.3kW51.88.0kW51.810.0kW62.54.706kW73.33.2kWTable 3.4 Calculation result ofBRFS60/100-BRDS60/100NoVOUTR TRM10.7OPEN21.046.6kW31.228.0kW41.517.5kW51.812.7kW+VOUTTRMGNDR TRMLoadFig.3.4 Connecting BRFS30/40/60S-BRDS40/60S+VOUT+TRM-TRMGNDR TRMLoadFig.3.5 Connecting BRFS60/100/120/150-BRDS60/100/120/150!The output voltage should be set within the range of Figure 3.6(only BRFS150-BRDS150).!If it deviates from the range, the output voltage turns off.Input voltage [V]14.07.04.50.6Operating area1.1 1.8Output voltage [V]Fig.3.6 Operating areaBRFS/BRDS-18
