Features:
The module supports DC input voltage range of 5-30V and output voltage range of 0.5-30V, which can be easily adjusted as per requirement.
With a long-term output current capacity of 3A (can reach 4A with enhanced heat dissipation), this module can deliver a maximum output power of 35W (can reach 50W with enhanced dissipation).
The LCD displays both input and output voltage, output current, output power, output capacity, and output time. The module can be set to ON/OFF by default.
The module comes with anti-reverse connection protection at the input end to prevent burnout due to reverse connection. It also has anti-backflow protection at the output end, eliminating the need for an anti-backflow diode during charging. Multiple software protection mechanisms are available, and the protection threshold is adjustable. The module automatically turns off the output when the working parameters exceed the protection threshold.
The module can be used as an ordinary buck/boost module with over-current protection. It can also function as a high-power LED constant current driver module or DIY solar power controller and battery charger.
