Special Features

  • ✅The buck converter consists of a 36u thickened circuit board, a high-Q inductor with an output LED indicator, and a high-quality solid-state capacitor that can effectively filter out high-frequency noise
  • ✅Product parameters: the input voltage is DC 4.0~40V, 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, and the conversion efficiency is 92% ( maximum), the output ripple is less than 30mV, the switching frequency is 150KHz, and the operating temperature is -45°C to 85°C.
  • ✅NOTE: This is a buck module. The input and output connectors cannot be reversed. The input voltage must be higher than the output voltage. A radiator is required for long-term work above 2A/15W. When using it for the first time, it is necessary to turn the potentiometer counterclockwise more than 10 times.
  • ✅High efficiency: 150KHz internal oscillation frequency, low power consumption, high efficiency. The conversion efficiency is as high as 92%. The input terminal is protected by a diode, and the reverse connection will not burn the module. With overheat protection and short circuit protection
  • ✅Application: The LM2596 step-down converter can be used in fields where the input voltage is higher than the step-down output voltage, such as batteries, power transformers, etc. Buck modules can be used in many electronics projects.

How to Calibrate the Digital Tube Voltmeter

✅(Optional steps for the person who need a highly accurate voltage value)
➤Short press the left "ON/OFF" button to start up the digital tube voltmeter. Long press(>1s, ➤Long press(>4 seconds) the left button to enter self-calibration of voltage measurement(calibration range: -0.5-0.5V, factory setting is 0.0).
"IN" indicator lights = input voltage measurement calibration starts.
Then, long press(>2 seconds) the right "Mode" button, "OUT" indicator lights = output voltage measurement calibration starts.
Tap the left / right button to reduce / rise by one unit (since the voltage value of one unit is less than 0.1V,
you need to 1-5 times tap the button continuously, so that the voltmeter can change by 0.1V)
➤After calibration, long press(>2 seconds) the right "Mode" button to preserve the adjusted value(no loss with outage) and back to normal voltage display.

Kindly Note:

☑ Input voltage must be 1.5 V higher than the output voltage, no boost
☑ Do not reverse the input and output interface
☑Keep output under 2A (or 15W), and use a heat sink when for a long time working
