Feature Module parameters: 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 turbines Input voltage: 7-35V, Output voltage: 1.25-30V adjustable Output Current: 3A (more than 15W, please install heat sink, this item do not include HEAT SINK) Constant current range :0-3A (adjustable) revolving light current: constant current value * (0.1), 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 constant current value to 2A, then revolving light current is constant current of 0.1 times (0.1 * 2A = 0.2A). this version is 0.1 times fixed Feature: Dropout voltage: 2V Output power: natural cooling 15W, 25W with heat sink Conversion efficiency: 90% (up to 90% (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) (ambient temperature exceeds 40 °C, lower power use, or to enhance heat dissipation) Full load temperature rise: 45 °C No-load current: Typical 10mA (12V switch 4.2V) Load regulation: ± 1% Voltage regulation: ± 0.5% Constant accuracy and temperature: the actual test, the module temperature changes from 20 °C to 100 °C, less than 1% change constant current value (constant current value 1A) Dynamic response speed: 5% 200uS Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease), potentiometer close to the input is Voltage regulation (CV), potentiometer close to the output is current regulate (CC), Indicator: two-color LED charging indicator light red, fully charged light green (do not connect load light green) Output short circuit protection: Yes, constant current (constant current setting values) Input reverse polarity protection: Yes, Output to prevent reflux: Yes, the output has an internal series a diode to prevent reflux. Connection: Welding, plus pin 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.)   Package  DC-DC voltage converter module X 1pcs WELCOME TO MY EBAY STORE http://stores.ebay.com/skt-flyer Thanks a lot for your attention!  :) We aim to provide high quality products and a greater service to you and a five'' stars* rating from you for each and every transaction is welcome.
