RIPPLE TESTING DEMONSTRATION:
TYPICAL APPLICATION CIRCUIT:
TYPICAL APPLICATION GUIDE:
  1. Recommended circuit: Typical application circuit is shown as Figure 1. If EMC performance is not required, Circuit in frame of dashed line can be removed.
  2. Clearance and creepage: for application Environment of Class I and Class II devices, users should guarantee there is clearance no less than 2mm and creepage no less than 2.5mm between L and N before the fuse.
  3. Fuse, 1A/250V or 10Ω/2W wire-wound resistor.
  4. Input filtering capacitor. Terminals 22 and 26 are internal rectification and filtering terminals. To protect the models further, it is recommended to connect an electrolytic capacitor C4 (it is recommended to be 4.7uF/400V). If operation voltage of the module is between 160~264VAC, C4 can be removed.
  5. Input EMI filtering network.(Refer to Figure1) Combination of NF, C1, C2 and C3 form input EMI filtering network.
    MOV: pressure sensitive resistor, model 471KD07
    C1: X capacitor, recommended parameter 0.01uF/275V
    CY: 102K/400V (Y1 CAP)
    NF: common model choke, UU9.8 or ring core, inductance is about 10mH, wire diameter 0.22mm.
  6. Output filtering capacitor C5 is electrolytic capacitor. To make sure the product work at perfect operation status with full loading external capacitor is necessary and it is recommended to use high frequency low resistance electrolytic capacitor. The isolation voltage derating of capacitor is larger than 80%. Please refer to manufacturer’s datasheet for capacitance and current parameters.
  7. "Z" is a TVS to protect post circuits (when module works incorrectly), is recommended.
  8. Refer to RIPPLE TESTING DEMONSTRATION,C6 is recommended to be 0.1uF.
