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

Feature:Name: 3A 35W Step-Up Down Power Supply ModuleInput Voltage: 5V-30VOutput Voltage: 0.5V-30VOutput Current: 3A for long time steady operation, up to 4A after enhancing heat diationOutput Power: natural heat diation 35W, enhanced heat diation 60WTransfer Efficiency: approx. 88%Working Frequency: 180KHzShort-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: NOModule Size: 65x32x21mm1. The use as a step-up down module with over-current protectionAdjust 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 moduleAdjust 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 Include:1 * 3A Step Up Down Power Module Constant Voltage and Constant Current
