BRFS60/100/120/150-BRDS60/100/120/150+TRM-TRMReference 3.5!Between input and output is not isolated ."Adjustable voltage range"!The BRFS/BRDS series handle only the DC input.Avoid applying AC input directly.It will damaged the power supply.Table 1.1 External partsNo.PartsReference1F1:Fuse2.1(1) External fuse2Ci:External output capacitor2.1(2) External input capacitor3 R TRM:Resistance for adjustmentoutput voltage3.5 Adjustable voltage rangeBRFS/BRDS-162.1 Wiring input pin(1) External fuse!Fuse is not built-in on input side. In order to protect the unit, installthe normal-blow type fuse on input side.ModelRatedcurrentTable 2.1 Recommended fuse (normal-blow type)Fig.1.2 Connection for standard use of BRFS60/100/120/150-BRFS30/40-BRDS40BRFS60/60S-BRDS60/60SBRFS100-BRDS100BRFS120-BRDS120BRFS150-BRDS15040A 60A 80A 100A 125A!When the input voltage from a front end unit is supplied to multipleunits, install the normal-blow type fuse in each unit.!When the fuse is open, power good signal is not outputed.(2) External capacitor on the input side!Install an external capacitor Ci, between +VIN and GND input pinsfor low line-noise and for stable operation of the power supply.Use ceramic capacitors for the external capacitor Ci.Table2.2 Recommended external input capacitor(Ceramic)ModelRecommended CiVin=5V Vin=12VBRFS30/40/60S-BRDS40/60S8×22mF4×22mFBRFS60/100-BRDS60/1008×22mF4×22mFBRFS120/150-BRDS120/1502×22mF2×22mF!Ci is within 5mm for pins. Make sure that ripple current of Ci isless than its rating.!When an impedance and inductance level of the input line becomehigher, the input voltage may become unstable. In that case, theinput voltage becomes stable by increasing Ci.!Note that the input voltage may increase due to the regenerativeoperation of the power supply, when starting up with residual voltagein the output or when the output voltage is sharply reducedusing the SEQ pin or TRM pin.(3) Recommendation for noise-fi lter!Install an external input fi lter as shown in Fig.2.1 in order to reduceconducted noise.
