Wide voltage input range, suitable compatible with a variety of solar panels and other DC power systems. Built-in MPPT technology, intelligent tracking of the maximum power point, significantly improve the energy conversion efficiency. Supports constant voltage and constant current output modes to meet the precise charging requirements of different battery packs. Equipped with intuitive display, real-time monitoring of key parameters such as voltage, current and power. High current output capacity up to 20A, suitable compatible with industrial equipment, outdoor energy storage and DIY electronic projects. 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 x 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-and85 ℃ Color: As Shown Material: MetalandPlastic Package Contents: 1 x 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.
