9V 12V 19V 24V Precise Converter 12V-90V to 9V 12V 19V 24V Step Down Converter Power Supply Module Board 4A

Features: The power supply adopts isolation design, and the biggest advantages of isolated power supply is high safety and reliability. Because there is not direct current between input and output.
Even after the power supply is abnormal, the damage to the load is very small. For example, the input Voltages will not be added to the output terminals after the break down of the switching tube, which will cause damage to the load.
Input reverse connection protective: with tube input reverse connection protective.
This power supply can step down and stabilize Voltages, and at the same time, it can step up and stabilize Voltages. (Load capacity is halved when boosting)
It is suitable for supplying power to products with power reliability requirements.

note: 1. This product is a constant Voltages power supply, and cannot be used in products requiring constant current, such as charging batteries or driving LED lamp with constant current.
2. This power supply can step down and stabilize the Voltages, and at the same time, it can step up and stabilize the Voltages, for example, the output is 19v, and the input is 12v-90v. Under the boosting condition. The load capacity will be by half.
