PPM-Series

PPMxx-x-xxZSLF

5 - 20 W AC/DC CONVERTER ISOL./SEP. TWIN OUTPUT

App Notes

Remarks :

1.Ripple and Noise were measured by the method of parallel lines;

2.Unless otherwise specified, all specifications above are measured at rated input voltage and rated output load,

TA=25°C, humidity < 75%;

3.All specifications stated in this datasheet are subject to the above listed model only. For specifications of

non-standard model, please contact our technical support team.

Remarks

1.Output filtering capacitor C5, C3 and C1 are electrolytic capacitor. It is recommended to use high frequency

and low resistance electrolytic capacitor. For capacitance and current of the capacitor please refer to

suppliers’ specifications. Voltage derating of capacitor should be 80% or above.

C2, C4 and C6 eliminate

high frequency noise. TVS is a recommended component to protect post-circuits (when converter fails).

2. External input NTC is recommended to use 5D-9 (Only PPM10 model and PPM15 model)

Specification can be changed without notice.
