Specification: Item Type: DC to DC Converter Material: PCB Function: DC to DC Converter Input Voltage: DC6-40V Output Voltage: 1.2-35V DC continuously adjustable for a long time below 32V, suitable for applications where the input voltage is higher than the output voltage and cannot be boosted. Output Current: 20A maximum, within 15A for a long time. Please add a fan for heat dissipation if the temperature of the power tube exceeds 65 degrees, and derate for high voltage output. Current Limiting Range: 0.2-20A adjustable. If the module exceeds 65 degrees, please add a fan. Minimum Dropout Voltage: 3V Working Frequency: 150KHZ Conversion Efficiency: Up to about 96%. The efficiency is related to the pressure difference and the use environment. Output Ripple: About 50mV ripple without no noise. 20M bandwidth, whihc is for reference only. Measured 24V input. Operating Temperature: -10 degrees Celsius to +75 degrees Celsius . Please pay attention to the temperature of the power tube in actual use, if the temperature is too high, please strengthen the heat dissipation or derate. Potentiometer Adjustment Direction: Clockwise to increase, counterclockwise to decrease. Output Short Circuit : Yes, instantaneous and constant current, and currently set constant current value cannot be short circuited for a long time. Wiring Method: Terminal Block Synchronous Rectification Technology Introduction: Synchronous rectification is a new technology that uses special power MOSFETs with extremely low on state resistance to replace rectifier diodes and reduce rectification losses. It can greatly improve the efficiency of the DC to DC converter and there is no dead time voltage caused by the Schottky barrier voltage. Power MOSFET is a voltage controlled device, and its volt ampere characteristics are linear when it is turned on. When using a power MOSFET as a rectifier, the gate voltage must be synchronized with the phase of the rectified voltage to complete the rectification function, so it is called synchronous rectification. Synchronous rectification technology greatly reduces the rectification loss at the output end of the switching power supply, thereby improving the conversion efficiency and reducing the heat of the power supply itself. Package List: 2 x DC to DC Converter Note: Scope of Application: For high power LED constant current drive, lithium battery charging, 4V, 6V, 12V, 14V, 24V battery charging, NiCd NiMH battery and battery pack charging, solar panels, wind turbines.
