Adjustable DC-DC Step-down Constant Current Regulator Module for Charging or LED Driver

The 5A 75W large power module features several functionalities, including current limit, voltage stabilization, and step-down. Additionally, it can be utilized as a high-power LED constant current driver module and a charging module for the USB connector's lithium battery.

The module offers two distinct work modes: constant voltage and constant current. The red indicator light serves to display the current working status, with the light being on for constant voltage mode and off for constant voltage mode.

Incorporating current limit, short circuit, and over-temperature protection, the module is designed to be safe and prevent burnout even if the output is short-circuited. However, it is crucial to avoid reverse connection at the input port, as this could result in the module being burned out.

When used as a charging module for a lithium battery, the blue light indicates that the battery is charging, and the blue light turning off with the green light turning on signifies that the charging process is complete.

The module is equipped with two high-precision voltage and current potentiometers, allowing users to adjust the output voltage and current by rotating the corresponding screws.

In addition to the module's features, it is worth noting that the large power rating of 5A and 75W make it suitable for a wide range of applications, such as powering high-power LED arrays or charging high-capacity lithium-ion batteries.

The constant voltage and constant current modes provide flexibility, enabling the module to be used in different scenarios, from powering LED lighting systems to charging portable electronic devices.

The integrated protection features, including current limit, short circuit, and over-temperature protection, ensure the module's reliability and safety, making it a robust and dependable solution for various power management applications.

The ability to adjust the output voltage and current through the high-precision potentiometers allows users to fine-tune the module's performance to meet their specific requirements, further enhancing its versatility.

Overall, the 5A 75W large power module offers a comprehensive set of features, making it a valuable tool for powering and charging a variety of electronic devices and systems, while maintaining a high level of safety and reliability.
