Feature: Module Properties: non-isolated step-down constant current, constant voltage module (CC CV) charging module Scope: High-power constant current LED driver, battery charger (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride batteries (battery) charger, solar panels, wind generators. Input voltage: 5-35V Output voltage: 1.25-30V adjustable Output Current: Rate 3A, Max 4A ( If more than 15W, please install the heat sink, this item do not include heat sink) Constant current range :0-4A (adjustable) Revolving light current: constant current value * (1% -100%), Revolving light current value Linkage with the constant current value, such as the constant current value is 3A, Revolving light current is set to constant current of 0.1 times (0.1 * 3A = 0.3A) when adjusted to the constant current value when the 2A, then Revolving light current is 0.2A (0.1 * 2A = 0.2A). Default 0.1 times Minimum voltage pressure: 2V Output power: natural cooling 15W, (if install heat sink can be 25W) Conversion efficiency: 92% (the higher the output voltage, the higher the efficiency) Output ripple: 20M bandwidth (for reference) Input 12V Output 5V 3A 60mV (MAX) Operating Temperature: Industrial (-40°c to +85°c) (if ambient temperature exceeds 40 °c, please lower power use, or to enhance heat dissipation) Full load temperature rise: 45°c No-load current: Typical 10mA (12V to 4.2V) Load regulation: ± 1% Voltage regulation: ± 0.5% Dynamic response speed: 5% 200uS Potentiometer adjustment direction: clockwise (increase), counter clockwise (decrease) Size: 49mm x 24mm Note: Potentiometer adjustment direction: clockwise (increase), counter clockwise (decrease) Indicator: constant current Indicator Red, Charging indicator Red, Full charge indicator Blue. Output short circuit protection: Yes, constant current (constant current setting values) Input Reverse Polarity Protection: None (Please Series diode at the input port.) Connection: Welding, can be directly soldered to a PCB Battery Charging method: 1. Make sure the recharge battery float voltage and charge current, input voltage of the module. 2. adjust constant voltage regulator, the output voltage about 5V. 3. With a multimeter ( to 10A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current reaches a predetermined charge current value; 4. Adjust Constant regulator allows Output voltage reaches the float voltage; 5. connected to the battery, try charging. (1,2,3,4 step input connect power, output do not connect battery.) LED constant current driver Usage: 1. Make sure LED current and the maximum operating voltage; 2. adjust constant voltage regulator, the output voltage about 5V. 3. With a multimeter ( to 10A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current reaches a predetermined LED working current value; 4. Adjust Constant regulator allows Output voltage Reach LED maximum working voltage; 5. Connected to the LED, test. (1,2,3,4 take steps input connect power, output do not connected LED.)
