Note
1. In order to obtain a more stable voltage, it is recommended that the output is greater than 15MA.
2. V- cannot be used alone, or no voltage output.But you can just use V+ .
3. The startup current of the module is 2.5-3 times the operating current.
4. Increasing the 1UF-10UF MLCC capacitor reduces the startup current.
The maximum output power can reach 20W, but the maximum power will vary under different conditions. For details, please refer to the following table(10-80% of the maximum power is the most reliable)
5V/±5V Output
6V/±6V Output
9V/±9V Output
10V/±10V Output
12V/±12V Output
15V/±15V Output
24V/±24V Output
Package Included
10 x 3.6-30V to ±3-30V Adjustable Output DC Converter Board
