With Housing 5A Constant Voltage Constant Current Buck Module 1. Input voltage: 5-36V (the input voltage above 6.5V is required for the on-board voltmeter to be effective) 2. Output voltage: 1.25-32V continuously adjustable (for use as a step-down module, the input must be greater than the output by more than 2V) 3. Output current: adjustable, up to 5A (recommended to be used within 4.5A, constant current needs to be output power above 2V to be adjustable, current adjustment will only work in constant current state) 4. Output power: up to 75W (recommended to be used within 50W, please reduce the power when using a large pressure difference) 5. Working frequency: 180KHZ 6. Short circuit protection: yes 7. Over-temperature protection: yes (automatically turn off the output after over-temperature) 8. Wiring method: wiring terminal or welding terminal, V-IN is input, V-OUT is output 9. Size: about 6.82x3.88x1.5cm 10. Weight: about 73g Features: 1. With crystal case, safe and practical, convenient and exquisite 2. On-board voltage, current, power meter, simple and intuitive 3. The onboard USB interface can easily charge digital products (note: the USB output voltage is the same as the module output voltage, not a fixed 5V output, please confirm before charging USB devices) 4. High power, high efficiency, 5A, low ripple 5. Can be used as an ordinary step-down module with overcurrent protection capability 6. It can be used as a charger for various voltage values ??of lithium batteries, batteries, silver-cadmium silver-hydrogen batteries (battery packs), and used in solar panels, wind turbines, etc. 7. Used as a high-power LED constant current driver module 8. There are two modes of constant voltage and constant current, and there are indicators to indicate which mode the module is currently in. 9. When used as a lithium battery charger, you can set the floating charging voltage and charging current, and there is an indicator light to indicate whether it is charging or h
