Design Reference 1. Typical application circuit +Vo -Vo AC (L) AC (N) C1 T VS MOV + C2 RL AC(L) AC(N ) FUS E Fig. 1 Model C1(µF) C2(µF) TVS tube LD10-20B03 1µF/50V 220µF /10V SMBJ7.0A LD10-20B05 220µF /10V SMBJ7.0A LD10-20B09 120µF /25V SMBJ12A LD10-20B12 120µF /25V SMBJ20A LD10-20B15 120µF /25V SMBJ20A LD10-20B24 68µF /35V SMBJ30A Note: Output filtering capacitors C1 is ceramic capacitor, it is used to filter high frequency noise. C2 is electrolytic capacitors, It is recommended to use high frequency and low impedance electrolytic capacitors. For capacitance and current of capacitor please refer to manufacture’s datasheet. Voltage derating of capacitor should be 80% or above. TVS is a recommended component to protect post-circuits (if converter fails). External input MOV is recommended to use S14K300. 2. EMC solution-recommended circuit AC(N) AC(L) AC(N) AC(L) LCM MOV CX CY1 CY2 AC/DC FUSE L1 R1 C1 TVS + C2 RL +Vo -Vo R2 Fig 2 Element model Recommended value MOV S14K300 CX 0.1µF/275VAC L1 4.7µH/2.0A CY1/ CY2 1nF/400VAC LCM 2.2 mH,recommended to use MORNSUN’s FL2D-10-222 R1 12Ω/3W FUSE 2A/250V,slow fusing 3.For more information about Mornsun EMC Filter products, please visit www.mornsun-power.com to download the Selection Guide of EMC Filter |
