Sell CC CV Adjustable 3A 35W DC 5-30V to DC 0.5-30V Step Up Down Buck Boost Converter Power Supply Module Voltage Regulator best price

Feature: Name: 3A 35W Step-Up Down Power Supply Module Input Voltage: 5V-30V Output Voltage: 0.5V-30V Output Current: 3A for long time steady operation, up to 4A after enhancing heat dissipation Output Power: natural heat dissipation 35W, enhanced heat dissipation 60W Transfer Efficiency: approx. 88% Working Frequency: 180KHz Short-Circuit Protection: YES (Automatically shut down output after short circuit protection, and renew by power-on again) Low-Voltage Protection: YES (Default is 4.2V, under 4.2V, it will auto shut down output, and renew by power-on again) Reverse Connection Protection: NO Module Size: 65x32x21mm 1.The use as a step-up down module with over-current protection Adjust the CV constant voltage potentiometer to the voltage you need, and adjust the CC constant current potentiometer to the over current protection value, when the output current value is up to the protective value, the red indicator light on, otherwise light off. 2.The use as a batter charging converter module Adjust the CV constant voltage potentiometer to floating charge voltage, and adjust the CC constant current potentiometer to charging current, the current diminishes in charging, constant current charge turns to constant voltage charge, blue light goes off, when the green light is on, battery charge complete. 3.Use as a large power LED constant current drive module. Note: 1.Please make sure the power of power supply be always greater than the output load needed. 2.For full output, the input voltage must be more than 8V. If the input voltage is more than 5V, the output power is approx. 15W. Package: 1 * 3A Step Up Down Power Module Constant Voltage and Constant Current
