DC-DC 28~120V to 5V 1A Isolated Step-Down Converter Power Supply USB Module
The power supply adopts an isolated design, and the biggest advantage of the isolated power supply is high safety and reliability, because there is no direct current loop between the input and output. Even if the power supply is abnormal, the damage to the load is very small. For example, after the switch tube breaks down, the input voltage will not be added to the output end to cause damage to the load. At the same time, the power supply has input anti-reverse connection protection, and the output has short-circuit protection. It is suitable for power supply of products that require relatively high power reliability.
