Notes:

* Fuses and varistors are basic parts of protection circuits (required).

* If the certification is required, the safety capacitor and common mode inductance cannot be omitted.


Output filtering

image

For usual requirements of ripple and noise, the peripheral recommendation is only C2; 

For strict requirements of ripple and noise, the above circuit is recommended. Notes:

(1) C2, C3 use high frequency low resistance electrolytic capacitor, and the total capacity can not exceed the maximum capacitive load indicated in the manual, otherwise the module will not start normally. (2) When the capacitive load is used, the minimum load of 3% must be guaranteed, otherwise the module output will be abnormal.
