Description LED driver with constant current power supply step-down Specification: Module parameters Input: IN + input is level, IN-type negative Output: OUT + output is level, OUT-output negative 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 turbines Input Voltage :5-35V Output voltage: (1) adjustable (1.25-30V continuously adjustable) (2) requires a fixed output (1.25-30V choose between), your purchase, please tell the shopkeeper. (Note: only for volume customers, all of the samples made adjustable voltage) Adjustment method: first the right then the input power (7-35V between) and then a multimeter to monitor and adjust the potentiometer output voltage (usually clockwise turn boost, buck turn counterclockwise) Output voltage: adjustable (1.25-30V no load adjustment) Our default shipping 4.2V voltage regulator for other voltage can be their own (or tell the shopkeeper.) Output current: rated 3A, the largest 4A (more than 15W, please install the heat sink) Constant current range :0-4A (adjustable) Turn lamp current: constant current value * (1% -100%), turn the lamp current value with the constant interaction, such as the constant current value of 3A, turn the lamp 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 turn the lamp current constant current of 0.1 times (0.1 * 2A = 0.2A). Default had already shipped 0.1 times adjusted to Minimum pressure: 2V Output power: natural cooling 15W, Conversion efficiency: 92% (up to 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 to +85 ) (ambient temperature exceeds 40 degrees, lower power use, or to enhance heat dissipation) Full load temperature rise: 45 No-load current: Typical 10mA (12V switch 4.2V) Load regulation: ± 1% Voltage regulation: ± 0.5% Dynamic response speed: 5% 200uS Indicator: Red LED constant current charging indicator light red, light blue charging is completed Output short circuit protection: Yes, constant current (constant current setting values) Connection: solder wire directly on the PCB Battery use: 1 Make sure you need to recharge the battery float voltage and charge current, the module input voltage; 2 adjustable constant voltage potentiometer, the output voltage to about 3V. 3. 10A current with a multimeter measuring the output short-circuit current block, and adjust the constant current potentiometer allows the output current reaches a predetermined charge current value; 4 turn lamp current default shipping charge is 0.1 times the charge current (constant value), please adjust the switch for the lamp current adjustment potentiometer; (generally without adjustment) 5 adjustable potentiometer allows the output voltage reaches the constant float voltage; 6 connected to the battery, try charging. (1,2,3,4,5 take steps to block input power, output load does not take batteries.) LED constant current driver to use: 1 Make sure you need to drive the LED current and the maximum operating voltage; 2 adjustable constant voltage potentiometer, the output voltage to about 3V. 3. 10A current with a multimeter measuring the output short-circuit current block, and adjust the constant current potentiometer allows the output current to achieve the desired LED current; 4 adjustable potentiometer allows the output voltage constant pressure to achieve maximum operating voltage LED; 5 connected to the LED, the test machine. (1,2,3,4 take steps to block input power, output load is not connected LED lights.) Package Include: DC-DC step-up x 1 Recommended Products Check out my other items!
