Features [Easy to Operate] The adjustment part of the voltage regulation module adopts a direct adjustment knob, which is convenient for the operator to adjust the voltage. [High Conversion Rate ] The conversion rate of the buck module can up to 94 percent, with high working efficiency and low energy consumption. [Long Working Life] The circuit board of the buck module is PCB, which can work reliably for a long time and can meet your long term needs. [Embedded Installation] This buck module is embedded design, which saves space and greatly increases the scope of application. [High Configuration] The buck module adopts the original DIP package XL4016 voltage regulator chip with 100A dual rectifier bridge and large energy storage inductor, which is more suitable for the DC power PWM voltage regulator.
