Sensor Module for Arduino LM317 DC-DC Adjustable Converter Buck Step Down Power Module Power Supply

Description:

1. As an excellent voltage regulator,LM317 has the characteristics of high stability,high temperature resistance,high linearity,etc.The output voltage range can reach 1.25V~37V continuously adjustable,and the maximum operating current exceeds 1A (using a large radiator or Active cooling measures).The board has a rectifier bridge and a 1000uF filter capacitor,which can effectively reduce the output ripple and interference.

2. Output current range:when the pressure difference exceeds 10V,please ensure that the output current is <400m

3. ATerminals:AC input terminal (no polarity),DC output terminal V+ output positive, DC output terminal V- output negative

4. Operating temperature range: 0°C-100°C (in order to prevent over-temperature damage, you can increase the heat dissipation by yourself or use other active heat dissipation methods).
