Precise details:
Specification:
Name: DC-DC step-down module
Model: XH-M161
Input voltage range: 14V~40V
Output current: less than 3A
Product size: 32 x 32 x 12mm
Product weight: 12 grams
Note:
1. Inputting a voltage greater than 40V may cause permanent damage to the module. To ensure safety, it is recommended to use the input voltage within 35V
2. The output current needs to be less than 3A, more than 3A will burn the module
3. If the output current is greater than 2A (or the output power is greater than 10W) ​​for a long time, please add the heat sink input (IN+) positive and (IN-) negative. Output (OUT+) positive (OUT-) negative.
4. Input voltage range: 14V to 40V
5. The input voltage must be more than 1.5V higher than the output voltage. Cannot boost) Because it is a buck module, the input voltage must be higher than the output voltage.
Wiring:
A. Soldering, directly solder the power cord to the in (out) port
B. Insert the pin through the lead wire and use the connecting wire to connect
Precautions
A. It is recommended to use within 2A for long-term work, and add a heat sink to use
B. The input and output cannot be reversed, it will burn if connected reversely
C. In order to ensure stable output, the step-down module should keep the limit as small as 1.5V, the differential pressure is 14V, and the 40V input voltage range is large; the wide voltage design can operate within the range of 14-40V
Scenes to be used:
A. Supply power to electronic equipment. When the voltage required by the equipment, this module can be used to adjust the voltage.
B. System working voltage test, this module can be used to debug voltage when doing projects
C. Application: Industrial control motherboards, toys, model airplanes, single-chip computers, home appliances, communications, vehicle power supply security monitoring. Field collection, street lights.
Package included:
1 x Power supply module
