Features:
1: The power supply adopts an isolated design, and the biggest advantage of the isolated power supply is high safety and reliability
2: Input reverse connection protection
3: stable performance
4: Output short circuit protection
5: Solder-free wire terminals, easy to use.
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 MOS tube 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.

Note:
1. This product is a constant voltage power supply and cannot be used in products that require constant current, such as charging batteries or driving LED lights with constant current.
2. The power supply can be buck and regulated, and can also be boosted and regulated. For example, the output is 19 volts, and the input 12 volts-90 volts can be stable at 19V output. under boost conditions. The load capacity will be reduced by half.
