DC 10-75V 20A Adjustable Voltage Reduction Module MPPT Solar Charging Constant Voltage and Current Charging Module

Module Type: Non-isolated Synchronous Rectifier Buck Module Input Voltage Range: DC 10-75V Output Voltage Range: DC 2-60V (factory voltage is random, please adjust it by yourself after you receive it) Adjustable Range of Output Current: 0.1-20A (25A MAX) Minimum Difference Between Input and Output Voltage: Input Voltage*0.2 or so (the higher the output current is, the higher the voltage difference is) MPPT Voltage Setting range: 9-70V (MPPT function can be used as input undervoltage protection) Operating frequency: 120KHz Overcurrent protection: 26A Fuse Charging Indicator: Yes (charging red light, full of green light) Input Reverse Connection Protection: No (reverse fuse and protection diode) Output Anti-Reverse Flooding Protection: No (charging batteries must be added to the anti-reverse-flooding diode, otherwise it will burn the chip) Conversion Efficiency: up to 96% (efficiency is related to the input and output voltage difference, output current size) Fan interface: 12V 0.3A Temperature control around 42 ℃ to start Operating temperature: -20~+85 ℃ Color: As Shown Material: Metal+Plastic Package Contents: 1*step-down module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
