Note:
(1) The test method of ripple and noise twisted pair test method.
(2) The series module does not have the input anti-reverse function, it is strictly forbidden to reverse the in put positive and negative connection, otherwise it will cause irreversible damage to the module

Typical Application Reference Circuit( Recommended Parameters)

1. Conventinal applications

To further reduce the input and output ripple, a capacitor filter network can be connected to the input and output terminals, and the application circuit is shown in Figure 1.
However, care should be taken to select the appropriate filtering capacitor. If the capacitor is too large, it is likely to cause start-up problems. For each output, under the condition of ensuring safe and reliable operation, the recommended capacitive load value is detailed in Table 1. recommended capacitive load value details (Table 1).

3. Output load requirements

To ensure that the module works efficiently and reliably, the minimum output load must not be less than 10% of the rated load when in use. If the power you need is really small, please connect a resistor in parallel between the positive and negative terminals of the output (the sum of the actual power used by the resistor is greater than or equal to 10% of the rated power and the rated power of the selected resistor must be more than 5 times the actual power used, otherwise the temperature of the resistor will be higher).

Note:

1. The above is only a list of typical products. If you need products beyond the list, please contact our sales.
2. The maximum capacitive load indicates the maximum capacitive load that + VO or – vo can be connected to, If the value is exceeded, the product will not start normally..
