DC-DC Converters Bus Converter . Power Module TypeInstruction Manual1 Connection for Standard Use2 Wiring Input/Output Pin!In order to use the power supply, it is necessary to wire as shownin Fig.1.1.Reference : 2”Wiring Input/Output Pin”8”Temperature of measurement point”!Short the following pins to turn on the power supply.-VIN RC, +VOUT +S, -VOUT -SReference : 3.4”Remote ON/OFF”3.5”Remote sensing”!The CHS series handle only the DC input.Avoid applying AC input directly.It will damage the power supply.DCinputFuseCin ++VINRC-VIN+VOUT+S-S-VOUTLoadCin : External capacitor on the input sideFig.1.1 Connection for standard useTable 1.1 Recommended External capacitor on the input sideModelCHS12024CHS30024CHS40024Cin220 F or more660 F or more660 F or moreModelCHS6048CHS8048CHS12048CHS20048Cin66 F or more33 F or more47 F or more100 F or moreModelCHS30048/CHS38048/CHS40048/CHS50048CHS70048Cin200 F or more400 F or more2.1 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.!When the input voltage from a front end unit is supplied to multipleunits, install the normal-blow type fuse in each unit.Table 2.1 Recommended fuse (Normal-blow type)ModelInput voltage [V]CHS60 CHS80 CHS120 CHS200CHS30024--15A-20A (05/10/12/15)30A (24/28/32/48)485A7A10A15A15AModelInput voltage [V]CHS380CHS400CHS500CHS70024-40A--4820A20A30A30A(2) External capacitor on the input side!Install an external capacitor Cin, between +VIN and -VIN inputpins for low line-noise and for stable operation of the power supply.Capacitance Refer to Table 1.1Ta = -20 to +85C Electrolytic or Ceramic capacitorTa = -40 to +85C Ceramic capacitor!Cin is within 50mm for pins. Make sure that ripple current of Cinis less than its rating.(3) Recommendation for noise-fi lter!Install an external input fi lter as shown in Fig.2.1 in order to reduceconducted noise. For details refer to our website technicaldata.DCinput++VINRC-VIN+VOUT+S-S-VOUT+LoadFGFig.2.1 Recommended external input fi lter(4) Reverse input voltage protection!Avoid the reverse polarity input voltage. It will damage the powersupply.It is possible to protect the unit from the reverse input voltage byinstalling an external diode as shown in Fig.2.2.+VINDC IN-VINCHS-39Fig.2.2 Reverse input voltage protection
