PRODUCT DESCRIPTION LM2596 DC-DC Adjustable Step-Down Module LED Voltmeter Power Supply Module With Digital Display
Product Description:
Create similar products cost performance, create LM2596 with digital display module!! The LM2596 module on the market has no output short-circuit protection, output a short circuit, the module immediately damaged, current output capacity is less than 1.8A. This module uses the original LM2596, large chip, frosted surface, output short circuit protection, high current 3A.
Module highlights: 1. Comfortable price, intelligent and humanized design, cost-effective! 2. Onboard voltmeter, voltmeter can be self-calibrated, there will be no problem of voltmeter! Module performance and characteristics: ● With voltmeter display and voltmeter self-calibration. Using a more advanced voltage microprocessor, voltmeter error ±0.05V, range 0~40V. (To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V) ● Touch the key to switch the measurement of input or output voltage, and there is an indicator to show which voltage is being measured, and save the setting, even if the power off and start again. ● Voltmeter can be closed, when no need to touch the left button can be easily realized. ● With wiring terminals, no soldering iron can also be convenient to use, and keep welding wire wiring points. ● Input voltage 4.0~40V. (The input voltage must be 1.5v higher than the output voltage) ● Adjustable output voltage range 1.25V ~ 37V continuous adjustable. (Input voltage must be 1.5V higher than output voltage) ● Output current 3A, recommended to use within 2.0A, large current needs to strengthen heat dissipation. ● Output power 20W, more than 15W, please strengthen heat dissipation. ● High conversion efficiency, average in 88% (efficiency and input, output voltage, current, pressure difference) ● With reverse connection protection, reverse connection does not burn ● With overheating protection and short circuit protection function ● Size 6.1*3.4*12cm (Length * width * height) ● Weight: 22g Scope of application: This module can be used in the input voltage is higher than the output voltage of the step-down field, such as battery, power transformer, 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. Self-calibration method of onboard voltmeter: 1. When the on-board voltmeter displays the output voltage, long press the button on the right for 2 seconds and release it. The voltmeter and output voltage indicator light "OUT" blink synchronously, and then enter the output voltage adjustment mode; Similarly, when the voltmeter displays the input voltage, long press the button on the right for 2 seconds and release it. The voltmeter and the input voltage indicator light "IN" blink synchronously, and then enter the input voltage adjustment mode. 2. Tap the right button, and the voltage increases by one unit; tap the left button, and the voltage decreases by one unit; Because the voltage value of a unit is less than 0.1V, so you need to press 1-5 times to see the voltmeter changes by 0.1V, the specific continuous key several times depends on the current display voltage value, the higher the current display voltage, the fewer times to press; 3. After the voltage adjustment is complete, press the button on the right for 2 seconds and release it. At this time, you can exit the voltage calibration mode. Note: In this way, you only need to calibrate once to get the voltage value in the whole voltage range. This function is designed to meet your higher accuracy requirements, please feel free to use it. |
