Feature:1. Non-isolation boost module, can adjust the voltage and current, can charge the battery.2. LCD dual display of real-time voltage and current.3. With input reverse polarity protection and output anti backflow function.4. The module outputs constant current and voltage to stably power electronic device.5. 11-60V output voltage, output current up to 8A.Specification:Item Type: Step Up Power Supply ModuleInput Voltage: DC 10V-32VOutput Voltage: DC 11V-60V continuously adjustable (recommend not to over 55V)Output Current: Max 8A (More than 4A, please enhance heat dissipation)Output Power: Max 90W in natural cooling, Max 150W in enhanced heat dissipationConstant Output Current: 0.3-8AWorking Temperature:-40C ~ +85C (When ambient temperature is too high. please enhance heat dissipation)Working Frequency: 150KHzConversion Efficiency: Up to 95% (related to input and output voltage, current, voltage difference)Short Circuit Protection: NoneInput Reverse Polarity Protection: YesOutput Indicator: With charging indicator, charging - yellow, fully charged - blueOutput Anti Backflow: YesModule Size: 80x53x35cm / 31.5x20.87x13.78inCalibration:This module has calibration function, don't worry about the problem of inaccurate measurements. If you found inaccurate measurement, can use the following method of calibration. Just calibrate once for the first time use!Voltage Calibration: when power off status, keep press the "set" key. power on, enter the voltage calibration mode. then the LCD screen starts flashing. release the "set" key, press the "Set" button to increase, press the "ENT" button to reduction, until calibrated to the correct input voltage. For example: the input voltage is 12.65V, then the voltage was adjusted to 12.65V. then automatically saved after 2 seconds, power off,calibration is complete!Setting Instruction:Setting key to set the display node, it have three types:1. F-0 mode: Display output voltage2. F-1 mode: Display input voltage3. F-2 mode: Alternately display input or output voltageTip: Press the "SET" button to cycle through the three display modes, the corresponding indicator will be on or off, then press the "ENT" button to save and exit. if separate press 'ENT" button to switch backlit LCD screen.Using Instructions:Adjusting Voltage: under no-load conditions, adjust the "constant voltage potentiometer ADJ-V", so that the output voltage reaches the value you wantAdjustment Current: connected to the load, adjust the "constant current potentiometer ADJ-I", so that the output current reaches the current value you want (the factory default is more than 2A, if you want to adjust the current value is small. more counter-clockwise tune laps will change), if you do not need constant current,it don't need adjustmentIndicator color change instruction: Charge turn lamp current factory default is 0.1 times the charging current:battery during charging. the current is gradually reduced, gradually turned from the constant current charging to constant voltage charging, if the charging current setting is IA, then when the charge current is less than 0.1A. the charging yellow indicator light off, full of blue indicator lights up and the battery is fully charged.Package List:1 x Module1 Bag x Holder and ScrewsNote:The constant current mode will only happen when the actual load output current is larger than the set current. Otherwise, it will work in the state of constant pressure.
