LED Power Driver Constant Voltage / Current Adjustable CC CV Specification: Module Properties: Non-isolated step-down constant current, constant voltage module (CC CV) charging module. Input Voltage: DC 7~35 V Output Voltage: DC 1.25~30 V ( adjustable, O/p Voltage < I/p Voltage by 2V ) Output Current: rated 3A, the largest 4A (more than 25W, enhance heat dissipation ) Constant Current Range: 0~4A (adjustable) The minimum voltage difference: 2V Fully Charged Current: = Constant current Value * ( 0.01 ~ 0.99 adjustable ). eg, Constant Current value: 3A, adjustable potentiometer: 0.1, Full charged current= 3A*0.1 =0.3A, When Charging current = 0.3A, Blue LED Lihgting. Default : 0.1 Output Power: natural cooling 25W, Max 30W Efficiency: 92% (up 92%, higher Voltage output, higher efficiency ) Output Ripple: 20M Bandwidth, Input 12V ; Output 5V 3A 0.06mV (MAX) Full Load temperature rise: 45 °C Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease) Indicator: Constant current RED LED, Charging RED LED, fully charged BLUE LED No-load Current: Typical 10mA Load Regulation: ± 1% Voltage Regulation rate: ± 0.5% Dynamic response speed: 5% 200uS Output Short-circuit Protection : Yes, Constant Current Input Reverse Protection: None Operating temperature: Industrial grade (-40 °C to +85 °C) (ambient temperature exceeds 40 degrees, lower power use, or to enhance heat dissipation) Size: 49 x 23.5 x 13.3 mm ( L*W*H ) Without heat sink & shell, Please visit my store. Application: High-power LED constant current driver Lithium battery charging ( Including ferroelectric ) 4V, 6V, 12V, 14V, 24V battery charging Ni-Cd Ni-MH batteries (battery) charging Solar panels, wind turbines DIY DC Power Supply . . . . . . Charge the battery, Use Mothod: Battery float voltage and charge current, and module input voltage. Constant Voltage adjustment potentiometer, Let Output Voltage = Float Voltage. Short-circuit current measurement with a multimeter, Let Output Current = Charge Current. Connected to the battery, try charging. LED constant current driver, Use Mothod: LED operating current and maximum working voltage. Constant Voltage adjustment potentiometer, Let Output Voltage = maximum working voltage. Short-circuit current measurement with a multimeter, Let Output Current = LED operating current. Connected LED.
