AJMRTC 300W Adjustable DCDC StepDown Power Converter Module, DC 17100V Input to 350V Output 20A High Current Buck Regulator, Constant Voltage Constant Current Power Supply for Electronic DIY Lab T

AJMRTC highpower DCDC stepdown converter module is designed for highvoltage input conversion scenarios. It takes DC 17100V widerange input and converts it to continuously adjustable DC output from 3V50V, delivering up to 20A current and peak power up to 300W. Dualmode constantvoltage and constantcurrent function makes this board versatile, usable as a regulated lab power source, lithium battery charging controller or highpower LED driver. Adopting highefficiency synchronous rectification buck topology, the module lowers power dissipation during energy conversion. Builtin comprehensive protective mechanisms trigger automatically upon overcurrent, overheating, overvoltage and shortcircuit conditions to prevent hardware burnout. Onboard potentiometers allow users to set output voltage and current limit easily. Suitable for solar power conversion, equipment power modification and electronic experimental platforms. Adequate external heat dissipation is required when operating under longterm highcurrent load; do not exceed rated power parameters.
