The LM2596S with voltmeter
Module performance and characteristics:
With a voltage gauge display, the voltmeter can be self-calibrated.With a more advanced voltage microprocessor, the voltmeter error ±0.05V and a range of 0 to 40V. (To ensure the accuracy of the voltmeter, make sure that the input voltage is above 4.5V) (Note: The input voltage is lower than 4V, and the onboard meter meter not work.)
● Touch the button to switch the measured input or output voltage, and an indicator light displays the voltage being measured, and the settings are saved, even if the power is turned off and turned on again.
●The voltmeter can be turned off, and it can be easily realized by touching the button on the left when not in use.
●With wiring terminals, it is easy to use, no soldering iron is needed, and welding wire connection points are reserved.
●The input voltage is 4.0~40V. (The input voltage must be higher than the output voltage by more than 1.5v)
●Adjustable output voltage range 1.25V～37V continuously adjustable. (The input voltage must be 1.5V higher than the output voltage)
●The output current is 3A, and it is recommended to use it within 2.0A. High current needs to strengthen heat dissipation.
●The output power is 20W, please strengthen heat dissipation if it exceeds 15W.
●High conversion efficiency, an average of 88% (efficiency is related to input, output voltage, current, and pressure difference)
●With reverse connection protection, reverse connection will not burn
●With overheating protection and short circuit protection function
●Size 6.6*3.6*14cm (length*width*height)
Application range:
The module can be used in the step-down field where the input voltage is higher than the output voltage, such as batteries, power transformers, DIY adjustable regulated power supplies, 24V car pen meter power supplies, industrial equipment step-down, 12V to 3.3V, 12V to 5V, 24V to 5V , 24V to 12V, 36V～24V, etc.
Self-calibration method of on-board voltmeter:
1. When the on-board voltmeter displays the output voltage, press and hold the right button for 2 seconds and then release it. The voltmeter and the output voltage indicator light "OUT" flash at the same time to enter the output voltage adjustment mode; similarly, when the voltmeter displays the input voltage, press and hold the right button for 2 seconds and then release it, and the voltmeter and input voltage indicator light "IN" Flashing at the same time, enter the input voltage regulation mode and enter at this time
2. Click the button on the right to increase a unit voltage, and click the button on the left to decrease a unit voltage; since the voltage value of a unit is less than 0.1V, you need to press 1-5 times to see that the voltmeter has changed by 0.1V. The number of times depends on the voltage value currently displayed. The higher the voltage currently displayed, the fewer the number of times to press;
3. After the voltage adjustment is completed, press and hold the right button for 2 seconds and then release it. You can exit the voltage calibration mode at this time, and all parameter settings will be automatically saved after the power is turned off.
To
Note: With this adjustment method, you only need to calibrate once to obtain an accurate voltage value across the entire voltage range. This function is designed to meet your higher accuracy requirements, please rest assured to use it.

LM2596HV
Note: It is not allowed to work for a long time above 50V (it is recommended to use within 50V)
Pressure difference: at least 1.5V, because it is a step-down module to ensure stable output, please keep at least 1.5V pressure difference
Module parameters
1. Volume length 45*width 24*height 11mm (including potentiometer)
Input mode: IN+ input positive, IN- input negative conversion efficiency: below 92% (the higher the output voltage, the higher the efficiency)
Output mode: OUT+ output positive, OUT- output negative
1. Input voltage: 4.5-60V (note: it cannot work for a long time if it is higher than 50V)
Adjustment method: first correctly connect the input power supply (between 4.5 and 60V), then monitor the output voltage with a multimeter, and adjust the potentiometer (usually clockwise for step-up, counterclockwise for step-down),
Output voltage: (3-35V) continuously adjustable (no-load debugging is recommended).
Differential pressure: at least 1.5V
Output current: rated current 2A, no more than 3A
Output power: no more than 15W, static power consumption is only about 6mA. Wiring method: soldering, solder directly on the PCB after adding pins.
Working temperature: industrial grade (-40℃ to +85℃)
Load regulation rate: ±1%
Voltage regulation rate: ±0.5% (in order to achieve a higher output voltage when there is no load, but as long as there is a 1MA load, the output voltage is normal and does not affect the function, please rest assured.)
Short circuit protection: current limiting, overheating protection, self-recovery.
Advantages: Double-sided thickened high-quality black oil PCB board, all imported SMD aluminum electrolytic capacitors, high-Q high-power inductors, and each board has undergone strict technical testing, and all are individually packaged in anti-static protective bags.
Specially designed 2 screw fixing holes. The four input and output pads are all fixed holes with pin headers;
Input + input input-input input!
OUT+ output positive OUT- output beam
Points for attention:
When encounter output voltage cannot adjust, always be equal to input voltage when this kind of problem, please first counterclockwise rotate potentiometer 10 circles above, use a module to be able to adjust voltage normally. The default output voltage of the step-down module is about 20V.
