This versatile voltage regulator boasts impressive features: Input Voltage Range: DC 5-30V Output Voltage Range: DC 0.5-30V (adjustable) Output Current: 3A (sustained); up to 4A with improved heat dissipation Maximum Output Power: 35W (up to 50W with improved heat dissipation) Safety First: Reverse polarity protection on the input prevents damage from incorrect connection. Reverse current protection on the output eliminates the need for an anti-reflow diode during charging. Multiple software protection mechanisms are included, with adjustable protection settings. Output automatically shuts off when parameters are exceeded. Excellent Thermal Performance: Low output ripple with integrated filtering. Features a thick heatsink. Integrated boost functionality. Informative LCD Display: Clearly displays input/output voltage, output current/power/capacity/time. Module can be set to ON/OFF by default. Wide Range of Applications: Ideal as a step-up/boost module with overcurrent protection. Perfect for high-power LED constant current driver applications. Suitable for DIY solar power controllers and battery charging. Materials: Metal + ABS Color: Black Package Contents: 1 x Voltage Regulator
