Digital DC-DC 3.5-30V 100W Boost Step-up Module Converter Power Supply
LED Voltmeter Display

Product Description

Features: Output voltage: 3.5V-30V; output current 0-6A. Can precisely regulate output voltage & current. Input/output voltage can display alternately. Power state can be freely defined. Power-off function with button, reduce power consumption. Input with reverse connection protection (MOS reverse polarity protection circuit). Uses three LED to display the output voltage & other parameters in real time. Working Mode Instruction: Output voltage mode: Default display output voltage mode, LED indicator off; Input voltage mode: Press button switch to input voltage mode, LED indicator on; Alternating mode: Press button again, input/output voltage alternately display (3s); Press button again, switch to output voltage display; Memory mode: Keep pressing the button between 2s-4s, module automatically memorize current working state as the switched-on state; [0] represents the default display is output voltage after power on; [1] represents the default display is input voltage after power on; [2] represents the default display input/output voltage alternately; Stop working Mode: Keep pressing the button until the monitor does not display numbers (long press more than 4s) & release the button. LED lights & voltage display zero. At this time, it does not perform memory function. Click the button, the LED voltmeter starts working again.
