Feature

●High Efficiency: LM2596 Buck Converter Stably Output, Voltage Conversion Efficiency is Up to 96%. The Output Voltage is 1.25V-37V (Continuously Adjustable, the Input Voltage Must Be 1V Higher than the Output Voltage),the Output Current is 2A (Normal and Stable), the Maximum is 3A
●Wide Input Voltage Range: Input Voltage is DC 0~40V,The Digital Can Be Turn On or Off, to Show Input or Output Voltage. With Advanced Voltage Microprocessor, Self Calibration, the Voltmeter Error ±0.1V (Note: To Ensure the Accuracy of the Voltmeter, Please Ensure that the Input Voltage is Above 4V )
●Protection Functions:LM2596 Buck Converter With Reverse Voltage Protection,Over-Temperature and Short-Circuit Protection,Making it Much Safer to Use.The Input and Output Connectors Cannot Be Reversed. A Radiator is Required for Long-Term Work Above 2A/15W
●Wide Applications: It Can Be Used for the Input Voltage is Higher than the Output Voltage Step-Down Field, Such as Batteries, Power Transformers, DIY Adjustable Voltage Regulator Power Supply, 24V Vehicle Pen Meter This Power Supply, Industrial Equipment Step-Down, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V, etc.
●NOTE: for First Time Using, it is Necessary to Turn the Potentiometer Counterclockwise More than 10 Times. Press the Button Next to Voltmeter to Test Input Voltage or Output Voltage. Green LED Lights On when Testing Output Voltage; Red LED Lights On when Testing Input Voltage

How to Adjust Accuracy of Input/Output Voltage:

  • 1. Long Press the Button for more than 4 Seconds, then Release, Voltmeter and IN Led Flash in Synchronization Entering into the Input Voltage Calibration Mode.
  • 2. Press the Button in a Short Time (1 Second) to Adjust the Value (range from -0.5 - 0.5V), Positive means to Rises Units, Negative means to Minus Units. (Due to a unit is less than 0.1V, so you have to Continuously Press 1 to 5 times to see the Voltmeter change 0.1V).
  • 3. Long Press the Button for more than 2 Seconds and then Release to Enter the Output Voltage Calibration Mode.
  • 4. After Calibration, Long Press the Button for more than 2 Seconds all Parameters will be saved Automatically and Back to the Voltage Display.
