Notes:
1. C1 and C3 are electrolytic capacitors. They are required for both AC input and DC input.
2. For AC input, C1 is used as a
fi
lter capacitor. The recommended C1 value is 22
μ
F/400 V.
3. For DC input, C1 is used as an EMC
fi
lter capacitor. The recommended C1 value is 10
μ
F/400V. When the input voltage is above 370VDC, we recommend a 10
μ
F/450V capacitor.
4. C2 and C3 are output
fi
ler capacitors, we recommend high frequency and low impedance electrolytic capacitors. For capacitance and rated ripple current of capacitors refer to
the datasheets provided by the manufacturers, voltage derating of capacitors should be 80% or above.
5. C4 is a ceramic capacitor which is used to
fi
lter high frequency noise. C2, C3 and L1 form a pi-type
fi
lter circuit. For current of L1 and L2 refer to the datasheets provided by
the manufacturers, current derating should be 80% or above. TVS is a recommended component to protect post-circuits (if converter fails). We recommend using a 5D-9
external input NTC.
6. For standard EMC requirements, please refer to
fi
gure 2. If a higher EMC is required, please refer to
fi
gure 3.
7. All speci
fi
cations measured at Ta=25C, humidity <75%, 115 Vac & 230 Vac input voltage, and rated output load, unless otherwise speci
fi
ed.
