Safe protection: The module has anti-reverse protection on the input side, so it will not burn when there is a return connection. No need to add an anti-reverse diode when charging. Multiple software protection mechanisms are available, and the protection threshold is adjustable. If the module's operating parameters exceed the protection threshold, the output is automatically cut off. Data reference: The input voltage range is DC 5-30V; the output voltage range is DC 0.5-30V; the output current can be 3A for long-term use, if the heat dissipation is improved, it can reach 4A; the maximum output power is 35W, if the heat dissipation is improved, it can reach 50W LCD display: input/output voltage, output current/output power/output capacity/output time. The module can be set to ON/OFF by default. Good thermal performance: the output ripple is small and the filter is available. Thick heat sink. Built-in Buck-Boost Wide range of applications: the volt conversion circuit can be used as an ordinary Buck/Boost module with overcurrent protection; as a high-power constant current LED driver module; DIY Solar Power Controller Battery Charging DC Step Up Converter - Variable Voltage Regulation Input Voltage: 5-30V Output Voltage: 0.5-30V Output Current: Can work stably at 3A for a long time, and can reach 4A with enhanced heat dissipation Output Power: Natural heat dissipation 35W, enhanced heat dissipation 50W Voltage Indicator Resolution: 0.01V Power Indicator Resolution: 0.001A Conversion Efficiency: About 88% Soft Start: Yes Anti-reverse connector input Anti-reverse sprinkler output Automatic protection function Input undervoltage protection (adjustable from 4.8 to 30V, standard 4.8V) Output overvoltage protection (adjustable from 0.5-31V, standard value 31V) Output overcurrent protection 0-4.1A (adjustable, standard value 4.1A) Overload protection (adjustable from 0 to 50W, preset 50W) Overheat protection (adjustable from 80 to 110C, preset 110) Timeout protection (adjustable from 0 to 100h, default) Super capacity protection (adjustable from 0 to 60Ah, default off)
