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

lter capacitor. The recommended C1 value is 22

F/400 V.

3. For DC input, C1 is used as an EMC

lter capacitor. The recommended C1 value is 10

F/400V. When the input voltage is above 370VDC, we recommend a 10

F/450V capacitor.

4. C2 and C3 are output

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

lter high frequency noise. C2, C3 and L1 form a pi-type

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

gure 2. If a higher EMC is required, please refer to

gure 3.

7. All speci

cations measured at Ta=25C, humidity <75%, 115 Vac & 230 Vac input voltage, and rated output load, unless otherwise speci

ed.
