Note:

(1) For product model with output voltage ±5VDC or ±9VDC , the maximum output voltage accuracy is ±5% under 0% - 5% load condition 

(2) When tested according to the 0%-00% load working condition, the load adjustment rate is ±5% 

(3) 0%-5% load ripple & noise less than or equal to 5% Vo. Ripple and noise test method, Twisted pair test method, can add capacitive load at the output to reduce light load ripple

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.
