Please make sure that the temperatures ofpin terminals +VIN and -VOUT shown in right fi gure do not exceedthe temperatures shown in below.(b) CHS80-VOUT!If time or temperature of the refl ow soldering goes beyond theconditions, reliability of internal components may be compromised.Please use the unit under the recommended refl ow conditions.+VIN(c) CHS120-VOUTCTpTxTy2Ty1A A’B B' Ctime(s)AA'BB'C1.0 - 5.0C/sTy1:160±10CTy2:180±10CTy1 - Ty2:120s max1.0 - 5.0C/sTp:Max245C 10s maxTx:220C or more:70s max1.0 - 5.0C/sCHSNotes to use option“-S”!Solder iron or other similar methods are not recommended soldering method for option“-S”because it may not be able to retain connectionreliability between the PCB and the Pins. Solder refl ow is the acceptable mounting system for the option.!Option“-S”is not reusable product after soldered on any application PCB.Stress to the pins!When too much stress is applied to the pins of the power supply,the internal connection may be weakened.As shown in right fi gure, avoid applying stress of more than 19.6N(2kgf) to the pins horizontally and more than 39.2N (4kgf) vertically.!The pins are soldered on PWB internally. Therefore, do not pullLess than19.6NLess than19.6NLess than19.6NLess than19.6Nbend them with strong force.Less than!Fix the unit on PCB (using silicone rubber or fi xing fi ttings) to reducethe stress to the pins.Less than39.2N39.2N(option S)!The base plate at Option”B”and“BC”is attached by glue.When fi xed to cabinet with screw, fi x the power module before soldering the input and output pins to prevent the power modulebeing damaged.Stress to the product!CHS series transformer core and choke coil core are attached by glue.There is a possibility that the core will be removed and power supply will be damaged when they receive stress by the fall or somekind ofstress.!The base plate at Option”B”and“BC”is attached by glue.There is a possibility that the base plate will be removed and power supply will bedamaged when they receive stress by the fall or some kind of stress.? 509 ?CHS-29
