Description

Product features

1. 5A high power, high efficiency, voltage reduction and low ripple!

2. With power indicator!

3. The on-board voltmeter and voltmeter can be self calibrated without the problem of inaccurate voltmeter

4. With heat sink!

5. Give away the bronze pillars

Warm tips

Some customers reported that the output voltage of the module could not be adjusted and was always equal to the input voltage. When you encounter this problem, please rotate the potentiometer for more than 10 turns in reverse, and then use the module to adjust the voltage normally. Because when the decompression module leaves the factory, the silent output voltage is about 20V.

The nixie tube can display normally only when the power supply is more than 6.5V.

DC-DC Adjustable Step-down Module Digital-display 5A High-power 75W Better Than 2596 With Voltmeter

Product characteristics

This module is different from the lm2596 and xl4005 voltage modules on the market. Their chip design power is 15W and 50W respectively. The upgraded chip used in this step-down module of our store is superior to the similar products in terms of input and output voltage range, output power and efficiency. The power can reach 75W, with high cost performance.

1. With power indicator

2. With voltmeter display and voltmeter self calibration. Voltage microprocessor voltmeter error is 0.05v, measuring range is 040v. (Note: to ensure the accuracy of voltmeter, please ensure the input voltage is above 4.5V)

3. Touch the key to change the measured input or output voltage, and there is an indicator to show which voltage is being measured, and save the setting, even if the power is off and then on

4. The voltmeter can be turned off, which can be easily realized by tapping the left button when it is not needed.

5. With terminal block, it is easy to use without soldering iron, and the welding wire connection point is reserved.

6. The input voltage is 4.0 ~ 38V. (input voltage must be 1.5V higher than output voltage)

7. Adjustable output voltage range: 1.25V ~ 36V, continuously adjustable. (input voltage must be 1.5V higher than output voltage)

8. The output current can reach 5 A, which is recommended to be used within 4.5 a.

9. The output power can reach 75W.

10. High conversion efficiency, up to 96% (efficiency related to input, output voltage and current differential pressure)

11. Load regulation rate s (1) < 0.8%, voltage regulation rate s (U) < 0.8%

12. With overheat protection function

13. Size 66 * 39 * 18mm

14. Weight 28.9g

Usage method

1. When the on-board voltmeter displays the output voltage, long press the right button for 2 seconds, release the voltmeter and the output voltage indicator lamp "out" to flash synchronously, and enter the output voltage adjustment mode; similarly, when the voltmeter displays the input voltage, long press the right button for 2 seconds, and then release, the voltmeter and the input voltage indicator lamp "n steps flash, and enter the input voltage adjustment mode at this time

2. Tap the right button to increase the voltage by one unit, tap the left button to decrease the voltage by one unit; because the voltage value of one unit is less than 0.1V, you need to press 1-5 times continuously to see that the voltmeter has changed by 0.1V. The specific times of pressing the key depends on the current displayed voltage value. The higher the current displayed voltage, the less times of pressing

3. After the voltage adjustment, press and hold the right button for 2 seconds and then release it. At this time, you can exit the voltage calibration mode. All parameter settings will automatically power down and save this adjustment mode. You only need to calibrate once to get the accurate voltage value on the whole voltage range. This function is designed to meet your higher accuracy requirements. Please rest assured to use it.
