New Adjustable DC-DC LM 2596 Converter Buck Step Down Power Modul Regulator M9Y0:
Brand new and high quality.
1. comfortable price, intelligent, user-friendly design, with a super high price!
2. On-board voltmeter, voltmeter self-calibration, there will be no voltage meter is not accurate problem!
Module performance and features:
● 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 button to switch the measurement input or output voltage, and the indicator shows which voltage is being measured, and save the setting even after the power is turned off.
● Voltmeter can be turned off, when you do not need to touch the left button can be easily achieved.
● with terminals, no iron can also be easy to use, and keep the wire bonding point.
● Input voltage 4.0 ~ 40V. (Input voltage should be higher than the output voltage 1.5v above)
● Adjustable output voltage range of 1.25V ~ 37V continuously adjustable. (Input voltage must be higher than the output voltage 1.5V)
● Output current 3A, it is recommended to use within 2.0A, high current need to enhance heat dissipation.
● Output power 20W, more than 15W Please strengthen the heat.
● high conversion efficiency, an average of 88% (efficiency and input, output voltage, current, pressure-related)
● With reverse protection, reverse connection is not burning
● with thermal protection and short circuit protection
● Size 6.1 * 3.4 * 12cm (L * W * H)
This module can be used in the input voltage higher than the output voltage buck areas, such as batteries, power transformers, DIY adjustable power supply, 24V car notebook power supply, industrial equipment buck, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V and so on.
On-board voltmeter self-calibration method:
1. When the on-board voltmeter shows the output voltage, press and hold the right button for 2 seconds to release it. The voltmeter and output voltage indicator "OUT" synchronously. At this time, the output voltage adjustment mode is entered. In the same way, Input voltage, long press the right button for 2 seconds and then release the voltmeter and input voltage indicator "IN" flashing simultaneously, then enter the input voltage adjustment mode;
2. Press the right button, the voltage is increased by one unit, the left button is pressed, the voltage is reduced by one unit. Since the voltage value of one unit is less than 0.1V, you need to press continuously 1-5 times to see the voltmeter Variations of 0.1V, the specific number of continuous press depends on the current display voltage value, the current display voltage is higher, the less the number of press;
3. After the voltage is adjusted, press the right button for 2 seconds to release, then you can exit the voltage calibration mode, all parameters set automatically power-down save.
