Description

Voltage Regulator 300W 20A Step Down Module

With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current. The efficiency can be up to 96%, measured at 20A, converting 24V to 12V. It is designed with 75V/80A large current dual MOS tube. Input and output use high frequency low resistance electrolytic capacitor, low ripple, and gives a stable output. Wiring is convenient with these large current 30A screw terminals. The buck module has 2 heat sink that could enhance heat dissipation. When there is a big difference between input and output voltage, please decrease power and current. CityTech BD
