Feature: With a wide range of input voltage from 6V to 40V, the step-down converter can accurately adjust the output voltage and current. Features:Efficiency can be up to 96%, measured at 20A, converting 24V to 12V. It is designed with 75V/80A high-voltage dual MOS tube. Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output. The wiring is convenient with these high-voltage current 30A screw terminals. The module has 2 heat sinks, which can improve heat dissipation. When there is a large difference between the input and output voltage, the power and current should be reduced. Specification: Input Voltage: 6V to 40V DC (10V to 40V is suggested)Output Voltage: 1.2V to 36V DCoutput Rate: 20A(max), 15A (suggested)Efficiency: 95%(24V to 12V, 20A)Output Ripple: le; 50mV Wiring Method: TerminalShort Circuit Protection: Self-Recovery (Can Not Short Circuit for a Long Time)VO+: Positive OutputVO-: Negative Output+ IN: Positive Input-IN: Negative InputCV: Output Voltage RegulationCC: Output Current RegulationEN: Status, Low Voltage Output; Suspension, high voltage level is effectiveWhen input and output is common, constant voltage CV output no-load, constant current output CC Package includes:1x300W 20A constant current adjustable Step-Down converter voltage module
