Specifications:The deceleration converter can accurately adjust the output voltage and current.The efficiency can reach 96 percent, the measurement time is 20a, and 24V can be converted to 12V.It is designed with a large dual current MOS tube 75V/80A.Input and output adopt high frequency, low resistance, low wave, stable output capacitor.The wiring of these 30A high current screw terminals is very convenient.The buck module has 2 heat sinks to improve heat dissipation performance.When the input voltage and output voltage are very different, it will reduce power and current.When the input and output are grounded, no-load constant output voltage CV, DC constant output current.Item Name: Power ModuleMaterial: PCBInput Voltage: 6V to 40V DC (10V to 40V Recommended)Output Voltage: 1,2 V to 36V DCOutput Current: 20A (Maximum), 15A (Recommended)Efficiency: 95 Percent (24V to 12V, 20a)Output Wave: 50mVWiring Method: TerminalShort Circuit Protection: Automatic Recovery (Cannot Short Circuit for A Long Time)VO +: Positive OutputVO-: Negative Output+ Input: Positive Input-Input: Negative InputCV: Output Voltage SettingDC: Output Current SettingFeatures: Adjustable, Storing Voltage, DurableSize: 6cm x 5.3 x 2.7cm/2.36" x 2.08" x 1.06" (Approx.)Notes:Due to the light and screen setting difference, the items color may be slightly different from the pictures.Please allow slight dimension difference due to different manual measurement.Package Includes:1 x Power Module
