DC-DC 7-32V 10A Buck Converter Adjustable 200W For Battery/LED/Car Power Module Description: Features: Module Properties: Non synchronous rectifier,non-isolated buck,constant current& voltage, CC CV charging mudule Input Voltage: 7-32V Output Voltage: 1.25V - 28V(adjustable) Output Current: 10A Max, 8A for long time working Output Power: 200W Working Temperature: -40°C to +85°C Working Frequency: 300 KHZ Tranfer Efficiency: Max 95% (Efficiency is related with input,output voltage,current and voltage difference .) Constant Current Range: 0.3 to 10A (adjustable) Turn Lamp Current: Constant current value*(0.1),turn lamp current connect with constant current value ,for example when the constant current is 3A, turn lamp current is set to constant current 0.1 time (0.1*3A=0.3A). When the constant current value is 2A, turm lamp current is set for constant current 0.1 time (0.1*2A=0.2A) This version is fixed to 0.1 time (+-10%), Direction for charing or full of Tranfer effciency: Max 95% ( Efficiency is related with input,output voltage ,current and voltage difference.) Working Frenquency:300KHZ Output Ripple: Ripple is about 50mV( No noise) 20M bandwidth (For reference only ) input 24V ,output 12V 5A test result. Working Temperature : Industrial grade(-40°C-+85°C)(Please pay attention to the power tube temperature and strengthen the heatsink system when operating ) No Lload Current: Typical 20mA ( 24V tranfer to 12V) Load Regulation Rate: ±1%(Constanct voltage) Voltage Regulation rate: ±1% The precision of constant current and temperature :Constant current value is less than 5% when the testing temperature from 25 degree up to 60 degree.(Constant current value is 5A) Dynamic response speed : 5% 200uS Adjustting direction of potentiometer : Clockwise (increase), anticlockwise(decrease) Indicator (lamp):Two colors,red is charging while green is full of Output short circuit protection : Yes ,constant current (Constant current value is set up presently) Input reverse connection protection: No Output anti-flow-backwards protection : No, you need to add diode for battery Connection: Terminal Direction for charging battery: Make sure the floating charge voltage ,charging current and input voltage of rechangeable battery you need Setting the constant voltage potentiometer,and put the output voltage on about 5V Monitor output short circuit current by 10A current of multimeter ,and adjusting output current to the expected charging current by constant current potentiometer Adjustting the output voltage to the floating charge voltage by constant voltage potentiometer Connecting with the battery and try to charge (Step 1.2.3.4 are for module input connected with power,while no load output disconnected with battery.) Direction for LED constant current driver: Make sure LED working current and max working voltage you need to drive Adjusting the constant voltage potentiometer and put output voltage on about 5V Mornitor output short circuit current by 10A current of multimeter,and adjusting output current to expected LED working current by constant current Adjust the constant voltage potentiometer to LED max working voltage by output voltage potentiometer Connecting with LED ,and try to drive (Step 1.2.3.4 for module input connected with power,while no load output disconnected with LED max working voltage.)
