New DC-DC adjustable power supply module LM2596 regulator module with voltmeter display
Product parameters :
Product Name: DC-DC Adjustable Power Supply Module
With voltmeter display (trimmable)
Product size: 66 mm * 36 mm* 14 mm
(length x width x height)
Product weight: 23 g (including packaging)
Yan color: blue
Packing: single module electrostatic bag packaging
Material feed: FR4 + ELECTRONIC ELEMENTS
Input voltage 2.5 V -36 V
The output voltage 1.25V - 3 5 V (adjustable)
Output current 3A (maximum)
Conversion efficiency 92% (highest)
Output ripple <30mV
operating frequency 150 KHz
Operating temperature -45°C~ +85°C
Application range:
This module can be applied to the buck field where the input voltage is higher than the output voltage, such as battery, power transformer, DIY adjustable power supply, 24V car pen power supply, industrial
With voltmeter display , voltmeter error ± 0.1V, range 4 ~ 35 V. (Note: the input voltage is lower than 4V, the onboard voltmeter does not work and does not display)
● touch key to switch the measurement input or output voltage , and indicator light display which is being measured terminal voltage . The first time the default digital tube displays the input voltage, and the input indicator IN is on; when the button is touched, the digital tube displays the output voltage, and the output indicator OUT is on. And keep the last setting, even if it is powered off and then on.
●The voltmeter can be turned off . Press and hold the switch for more than 1 second and less than 4 seconds to release it . Once the voltmeter is turned off, simply press the switch to turn on the voltmeter.
● Input and output voltage measurement error calibration function , long press the switch for more than 4 seconds, after entering the hand, it will enter the voltage measurement error calibration function. At this time, the IN light is on (calibration input terminal), and the digital tube flashes to display the correction value (factory parameter is 0.0) ), at this time, press the button to change this value (the value range is -0.5~0.5, the unit is V), the positive number means upward calibration, and the negative number means downward calibration. After adjusting the comparison value of the input terminal, press and hold the button for more than 2 seconds, and then release the error calibration of the output terminal after releasing the hand. At this time, the OUT light is on (calibration output terminal), and the calibration value of the output terminal is displayed. The adjustment method is the same as the input end. After the comparison value at the output end, press and hold the button for more than 2 seconds. After releasing the hand, save the set value and return to the normal display voltage. The set correction value takes effect immediately and the power is not lost. (With this feature, you can meet your higher accuracy requirements)
●With terminal block, no soldering iron can be used conveniently, and retain the wire bond point
(The input voltage must be higher than the voltage to be output by 1v or more)
●Maximum output current can be as high as 3A , the recommended working current is about 2A, more than 2A plus heat sink
●Using 150KHz internal oscillation frequency, it belongs to the second generation of switching voltage regulator, with low power consumption and high efficiency.
●The input end is protected by diode, and the reverse connection will not burn out the module.
● With overheat protection and short circuit protection (more than 15W, please strengthen heat dissipation)
Some customers have reported that the module output voltage cannot be adjusted and is always equal to the input voltage. When you encounter this problem, please turn the potentiometer counterclockwise for more than 10 turns, then use the module to adjust the voltage normally. Because the buck module is shipped from the factory, the default output voltage is around 20V. -
