Feature:1. The DC-DC module efficiency can be up to 92%, on-board high-accuracy ultra-durable potentiometer, directly adjust the output voltage2. The module has output short-circuit protection, even if the output is short-circuited, it will not damage the module3. The module has overheat protection function, automatic protection beyond IC working temperature limit4. Suitable for LCD power board5. The input and output terminals are wired in the form of terminals6. The power input terminal is provided with an anti-reverse diode. Even if the power supply is accidentally connected, the module will not be damaged.7.
