The circuit board features a 1.6mm thick gold plating process. The input has a replaceable fuse for the power supply and equipment. The entire electrolysis version utilizes low resistance and high frequency capacitors, effectively reducing ripple to a minimum; it offers constant voltage, constant current, and under-voltage protection (more suitable for solar charging). There is an output error indicator that activates when the output voltage becomes excessively high or when a short circuit occurs. The oxidized heat sink effectively dissipates heat comparable to natural aluminum sheets; the inductor is made from iron-silicon-aluminum which generates less heat. When purchasing and using this voltage module, please read the instructions carefully, as the company will not be responsible for damage caused by improper use. This module acts as an automatic step-up and step-down power supply. When the input voltage is lower than or higher than the output voltage, it stabilizes the output voltage. When the output is set to 12V, with input voltage varying between 5 and 32V, the output remains constant at 12V. It includes constant current, constant voltage, under-voltage protection, output indication, fault indication functions, and provides overcurrent, over-voltage, and short circuit protection. All components comply with industrial standards and can be used in various applications, such as charging, high-power LED drivers, equipment power supplies, and vehicle power supplies. Electrical parameters: 1. Input voltage: DC5-32V, recommended voltage above 10V 2. Output voltage: DC1V-30V continuously adjustable 3.
