LM2596 Adjustable Power Module with Voltmeter

LM2596 Adjustable Power Supply Module with Voltmeter ( Steps Voltage Down )

Terminal Block Sockets  Voltage Adjustable Supply DC DC Converter 35V 3A Power Module

When you first receive the product, you may need to turn it 10-20 full turns counterclockwise to lower the voltage.

      It is a voltage adjustable power supply module. It is a ready made circuit whose output voltage can be adjusted very precisely (For example 5.05V) between 3V and 33V. The input voltage can be maximum 35V. It has 3A current sourcing capacity. Thanks to its very small dimensions, it is suitable for use in dc voltage conversion tasks in all kinds of circuits.

     There is a voltmeter on the module. The output voltage can be seen with this voltmeter. In this way you can easily adjust the output voltage.

Features:

• Input voltage : DC4.5V / 35V
• Output voltage: DC 3V / 33V ( Attention = The input voltage must be 1.5V higher than the output. )    
• Output current: Maximum 3A ( A heatsink must be used above 15W. )
• Monitoring of the input or output voltage with a 7 segment voltmeter.
• The button on the board allows selection of the input or output voltage display.
• 2 Pieces power indicator led.
• Efficiency: can rise up to 92%.
• Precise adjustment of the output voltage with the multi turn voltage adjustment potentiometer.
• Switching frequency: 150KHz 
• Reverse connection protection: None ( It would be good to add it in series to the supply + end. )
• Short circuit protection
• Operating temperature:  -20C / 85C (Below 10W)
• Terminal block sockets for easy connection at the input and output
• 4 smd pads that can be used for the supply connection
• Quality material and quality pcb.
• 4 Pieces mounting hole
• Dimensions: 56mm x 35mm
• Weight: 24gr

Potentiometer Use:

• The potentiometers are multi turn. They can turn 20-30 turns in both directions. Usually the mistake of turning very little and thinking the products do not work can be made. It is necessary to turn a lot to see the effect.
• Turning clockwise; increases the value for the relevant parameter. For example the voltage increases.
• Turning counterclockwise; decreases the value for the relevant parameter. For example the voltage drops.
