20A300W Step Down Buck Boost Power Adjustable Charger Board DC-DC Converter

Description: DC-DC Converter 20A 300W Step Down Buck-Boost Power Adjustable Charger BoardFeature:1: Made of high quality material, more durable.2: Electrolytic capacitor high frequency of low resistance, Low resistance, stable output.3: Module properties: synchronous rectification, non-isolated buck, constant current and constant voltage module, CC CV charging module.4: Scope of application: high-power LED constant current drive, lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, Ni-Cd Ni-MH battery (battery pack) charging, solar panels, wind turbines.Output current adjustment method:1. Adjust the CV potentiometer and set the output voltage to the voltage value you need according to your load requirements.2. Set the CC potentiometer counterclockwise about 30 turns (that is, set the output current to the minimum), connect the LED, and adjust the CC potentiometer to the current you need. For battery charging, after the battery is fully discharged, connect it to the output, and adjust the CC to the current you need. The more, the smaller the charging current.)Specifics:Condition: 100% Brand NewInput voltage: DC6-40VOutput voltage: Continuously adjustable (1.2-35VDC) 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: Maximum 20A within 15A for a long time (please add a fan for heat dissipation if the temperature of the power tube exceeds 65 degrees, and use derating for high voltage output)Current limiting range: 0.2-20A (adjustment) If the module exceeds 65 degrees, please add a fan.Minimum dropout voltage: 3VWorking frequency: 150KHZConversion efficiency: Up to about 96% The efficiency is related to the pressure difference and the use environmentOutput ripple: About 50mV ripple (no noise) 20M bandwidth (for reference only) input 24V measuredWorking temperature: -10℃ to +75℃) (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 the usePotentiometer adjustment direction: Clockwise (increase), counterclockwise (decrease)Output short-circuit protection: Yes (instantaneous protection) constant current (currently set constant current value cannot be short-circuited for a long time)Input reverse polarity protection: None,Output anti-backflow: None, for self-charged or inductive loads, an external 2-pole tube is required!Wiring method: Terminal blockModule size: 60*53*30 mm/2.36*2.09*1.18 inWiring Instructions:OUT+: output positiveOUT-: output negative+IN: input positive-IN: Enter a negative numberCV: Output Voltage RegulationCC: output current regulationEN: Enable, low level closes output; Pause, high voltage level activeWhen the input and output are grounded, no-load CV output constant voltage, CC output constant currentNote:1.Please allow 1-3mm difference due to manual measurement.2.Item color displayed in photos may be showing slightly different on your computer monitor since monitors are not calibrated same.Package Included:1 X Converter About USOur shop has been a ebay member since 2008 in USA,with a long history,a solid basic and rich experience.We are focus on Auto Parts,Car Parts,Motorcycle Parts,3C,other hot sale items and so on.We Appreciate every customer, We will do our best to serve each customer.We aim to provide to customers high quality product and best service.About Shipping&ReturnsThe item usually will be dispatched within 5 Days after your payment,but it usually takes 3-10 working days to delivery depends on buyers address or other majeure on the way.
