10PCSxDC Buck Step Down Converter Constant Current Voltage Power Supply Input: 7-35V, Output: 1.25-25V 0-3A DC Charger #090464 Product Description Feature: Module Properties: non-isolated Buck 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. Solar Panel, Wind generator voltage regulator, Car Power Supply. Input voltage: 7-35V Output voltage: 1.25-30V Output Current: Max 3A ( If more than 15W, please install the heat sink, this item do not include heat sink) Constant current range :0-3A (adjustable) Minimum voltage pressure: 2V Output power: natural cooling 15W Conversion efficiency: 85% (the higher the output voltage, the higher the efficiency 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% Current precision and temperature: Actual Testing, Temperature changes from 20 degrees To 100 degrees, Constant current value change Less than 1% (constant current value 1A) Dynamic response speed: 5% 200uS Potentiometer adjustment direction:Clockwise (increase),Counterclockwise (decrease) Indicator LED: Charging LED Red, Full Charge LED Green Output Short-circuit Protection:YES Input Reverse Polarity Protection:YES Output Prevent Countercurrent: YES 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 3V. 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 3V. 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.)
