DROK? LM2596 Numerical Control Voltage Switching Regulator DC Buck Converter with Red LED Voltmeter 35V to 24V to 12V to 5V Adjustable 5-34V to 0-33V Step Down Variable Volt Power Supply Stabilizers Car Battery Item Description Numerical Control: there are output voltage "-" button for decreasing output voltage and output voltage adjustment " +" for increasing output voltage. There are two buttons on the left side of the voltmeter, I is for input voltage display and O is for output voltage display. You can press one of the them to choose the voltmeter to display input voltage or output voltage. There are two LED indicators on this converter board, including the red LED and the green LED. The red LED will light on when you measure input voltage and green LED will light on when you measure output voltage. It is low power consumption, and has terminal and retain the wire bonding wiring point. SPECIFICATIONS Parameters: Input voltage: 5-35V Output voltage: 0-33V Output standard current: 2A Max current: 3A (we suggest you to leave margin) Output power: 30W Max Output current: 1.5A(please enhance cooling when > 1.5A) Output voltage preset resolution: 0.1V Voltage testing accuracy: +/-1%; +2 words Display frequency: 2 times/second Parameter set way: micro switch Operating Temperature: -10? ~ 40? Wiring connection: IN+: connect IN+ to your Input Positive IN-: connect IN- to your Input Negative Out+: connect OUT+ to your Output Positive Out-: connect OUT- to your Output Negative How to use: 1. Press the "I" button to test and show input voltage. 2. Press the "O" button to test and show output voltage. 3. Power on and load output voltage of last time when you power off. Test and display output voltage. 4. Short press the "+" or "-" button for 0.1 second, output voltage will increase or decrease 0.1V for per pressing and display position of 0.1 V will flash, then the module turns to adjust mode of output voltage; long press the "+" or "-" button for about 1 second, output voltage will increase or decrease 1V for per pressing and display position of 1V will flash, the board will turn to output voltage adjust mode; when you don't press the button for about 2 seconds, the module will operate the preset output value and turns to test and display mode of output voltage. Note: 1. Please make sure that you use this module within its working range; do not output short-circuit or charge the battery, or the board would burn. 2. When you set the parameter, please use the module after you make sure output voltage is stable to avoid any possible damage.
