Data reference: Input voltage range is DC 5-30V; output voltage range is DC 0.5-30V, can be adjusted arbitrarily; output current can be 3A for long-term use, if heat dissipation is improved, it can reach 4A; maximum output power is 35W, if dissipation is improved, it can reach 50W Safety protection: The module has reverse connection protection at the input side, so it will not burn out when reverse connected. Output side anti-reflow protection. No need for a reflow diode when charging. Multiple software protection mechanisms are available, and the protection is adjustable. When the module's working parameters reach the protection, the output will automatically shut down Good thermal performance: Output ripple is small and filter is available. Thick heat sink - boost integrated LCD displays: input/output voltage, output current/output power/output capacity/output time. The module can be set to ON/OFF by default. Wide range of applications: The voltage conversion board can be used as a /Boost module with overcurrent protection; used as a high-performance LED power control module; DIY a solar regulator, battery charging. Material: Metal+ABS Color: Black Package Contents: 1 x Voltage Regulator Only the above package contents, others are not included. Note: Light reflection and different displays may cause the color of the item in the picture to be slightly different from the real thing. The measurement allowed error is +/- 1-3cm.
