Synchronous Rectification Non-isolated Constant Current Constant Voltage Step Down Converter Module DC6-40V to DC1.2-35V Adjustable CCCV Battery Charging Module <<

This product is a synchronous rectification non-isolated constant current constant voltage step-down module. Synchronous rectification is a special power MOSFET with very low on-state resistance. The power MOSFET is a voltage-controlled device, which is linear in its voltammetric characteristics during conduction. When using power MOSFETs as rectifiers, the gate voltage needs to be synchronized with the phase of the rectified voltage to complete the rectification function, so called synchronous rectification. Synchronous rectification technology is to greatly reduce the rectification losses at the output of the switching power supply, thereby improving the conversion efficiency and reducing the heat of the power supplys itself. Features:This product is a synchronous rectification non-isolated constant current constant voltage step-down module. Synchronous rectification is a special power MOSFET with very low on-state resistance, which is linear in its voltammetric characteristics during conduction. When using power MOSFETs as rectifiers, the gate voltage needs to be synchronized with the phase of the rectified voltage to complete the rectification function, so called synchronous rectification. Synchronous rectification technology is to greatly reduce the rectification losses at the output of the switching power supply, thereby improving the conversion efficiency and reducing the heat of the power supplys itself.With the wide input voltage of 6.0V to 40V and 1.2-35VDC output voltage, this step-down converter can accurately adjust output voltage and current.The max conversion efficiency can be up to 96%, the output ripple is about 50mV (excluding noise), low ripple, stable output.Potentiometer direction adjustment: clockwise (increase) and counterclockwise (decrease) depending on your needs.When there is a big difference between input and output voltage, please decrease power and current.Scope of application: high-power LED constant current driver, lithium battery charging (including ferroelectric), 4/6/12/14V/24 V battery charging, Nickel-cadmium battery and nickel-metal hydride battery (battery packs) charging, solar panels, wind turbines. Output current regulation method:1, Adjust output voltage potentiometer, according to your load requirements, the output voltage set to the voltage value you need.2, Counterclockwise set output current potentiometer about 30 laps, (that is, the output current set to the minimum), connected to the LED, adjust output current potentiometer to the current you need. For battery charging, after the battery is discharged, and then receive the output, adjust output current to your desired current, (for charging needs to be used to discharge the battery to adjust only accurate, because the more power left in the battery, the smaller the charging current.
