Features:This is a non-isolated DC regulated power converter module with long service life.High power and stable output, it converts 5-30VDCto 1.25-30VDC.High quality components ensures high conversion efficiency, up to 93%.It supports over current, short circuit, over temperature protection.Designed with two heat sinks for better heat dissipation.Specification:Type: Non-isolated synchronous rectification automatically step up/down moduleInput Voltage: DC5-30VInput Current: 8A, (MAX) 10A, (within 6A for long-term work)Quiescent Current: 4mA (there will be deviation when working voltage is different)Output Voltage: 1.25-30V continuously adjustableOutput Current: 10A (MAX) (long-term natural cooling within 5A, please reduce rated value when output high voltage), enhance heat dissipation or reduce rated value when module temperature is over 65Constant Current Output Range: 0.2-10AOperating Temperature: -40 to +85Frequency: 150KHzConversion Efficiency: Typical 91%, maximum 93%Over Current Protection: YesShort Circuit Protection: Yes (current limiting protection)Over Temperature Protection: Yes (automatic reduce output voltage)Reverse Input Protection: No, please connect to a diode in series at input if neededOutput Flow Back Protection: Yes, do not need to add the diode when used for charging.Wiring Method: Terminal block output, (IN is input, OUT is output)Weight: 70g / 2.5oz (approx.)Package list:1 * ModuleCurrent Adjustment:1, Adjust the CV potentiometer, set the output voltage according to the load requirements.2, Rotate counterclockwise CC potentiometer about 30 circles, (i.e. the output current is set to minimum), connected to the LED, set CC potentiometer to required current.If you use the module for battery charging, connect to output after battery is fully discharged. Adjust CC to required current. Because if the more energy is left in battery, the less charging current will be.Please do not use short circuit to adjust current.
