dc-dc 7V-35V to 1.25V-30V step-down Buck power supply module LED driver constant current charging Description dc-dc 7V-35V to 1.25V-30V step-down Buck power supply module with charging indicator constant current instructions CC CV LED driver constant current charging #1200110 Modular nature:Non-isolated constant current and voltage module Rectification:Non-synchronous rectification Input voltage:7V-35V Output voltage:1.25V-30V Output current:Adjustable maximum 3A Conversion efficiency:92% (the highest) Switching frequency:150KHz Output ripple:50mV (max) 20M bandwidth Load regulation:± 0.5% Voltage Regulation:± 2.5% Operating Temperature:-40 ℃ to +85 ℃ Size:48 * 23 * 14 (L * W * H) (mm) ★ This module is adjustable buck module, the output voltage can be changed by adjusting the sinking of the module above blue adjustable resistor. Dropout voltage of 2V, the minimum output 1.23V voltage. ★ modules indicated above IN-(enter negative), IN (input positive), OUT-(negative output), OUT (output positive) must be connected correctly, or may result in damage to the module. ★ battery charging to use: 1 to determine if you need to charge the battery float voltage and charging current, the input voltage of the module; 2. Adjust the constant voltage potentiometer, the output voltage is adjusted to about 5V. Multimeter 10A current gear measuring the output short-circuit current, and adjust the constant current potentiometer to make the output current reaches a predetermined charge current value; Charging turn lamp current default shipped 0.1 times the charging current (constant value) To adjust adjust the turn lamp current potentiometer; (generally without adjustment) 5 Adjust the constant voltage potentiometer to make the output voltage reaches the float voltage; 6. Connected to the battery, try to charge. (1, 2, 3, 4, 5 step for the module input power supply, the output no-load is not connected to the battery.) ★ LED constant current driver to use: 1 to determine if you need to drive the LED current and maximum operating voltage; 2. Adjust the constant voltage potentiometer, the output voltage is adjusted to about 5V. Multimeter 10A current gear measuring the output short-circuit current, at the same time to adjust the constant current potentiometer to make the output current reaches a predetermined LED current; 4 Adjust the constant voltage potentiometer to make the output voltage reaches the the LED maximum working voltage; 5 connected to the LED, test machine. (1,2,3,4 steps for the module input power supply, the output no-load is not connected to the LED lights.) packing including: 1x step-down Buck power supply module Payment We only accept payments via paypal.
