5A 75W DC-DC Adjustable step-down Power module with LED voltmeter

Description

5A 75W DC-DC Adjustable step-down Power module with LED voltmeter
Package List:
1 x 5A 75W DC-DC Adjustable step-down Power module with LED voltmeter
1 x
heat sink
4 x Pillars with screw
Features:
1，With power indicator
2，With voltmeter voltage meter can display and self-calibration. Uses a more advanced microprocessor voltage voltmeter error ± 0.05V, range 0 ~ 40V. (Note: To ensure accuracy voltmeter, please ensure that the input voltage is 4.5V or more)
3，Touch of a button to switch the input or output voltage measurements and has a light display which is being measured voltages, and save the settings, even power off and then on.
4，Voltmeter can be turned off when not needed Tap the left button can be easily achieved.
5，With terminals, no soldering iron can also be easy to use, and retention wire connection point.
6，Input Voltage 4.0 ~ 38V. (Input voltage must be higher than the output voltage of 1.5v or more)
7，Adjustable output voltage range of 1.25V ~ 35V continuously adjustable. (1.5V input voltage must be higher than the output voltage)
8，Output current up to 5A, recommended for use in the 4.5A.
9，The output power of up to 75W.
10，high conversion efficiency, up to 96% (efficiency and input and output voltage, current, pressure related)
11，Load Regulation S (I) ≤ 0.8%, voltage regulation rate S (u) ≤ 0.8%
12，With overheat protection and short circuit protection
Onboard voltmeter self-calibration methods:
1, An on-board voltage meter display output voltage, long press the right button for 2 seconds after the release, and the output voltage voltmeter indicator "OUT" synchronous flashing, this time into an output voltage adjustment mode;. Similarly, the voltmeter shows When the input voltage, long press the right button for 2 seconds after the release, voltmeter and input voltage indicator "IN" synchronous flashing, then enter the input voltage adjustment mode;
2, Tap the right button, the voltage increases one unit, touch the left button, a voltage reduction unit; due to the voltage value of a unit is less than 0.1V, so you need to press 1-5 times in a row to see the voltmeter changed 0.1V, continuous button several times depending on the specific voltage value currently displayed, the higher the voltage the current display, the fewer the number of press;
3, After the voltage adjustment is completed, press the right button two seconds after the release, this time to exit voltage calibration mode, all parameters set to automatically power down to save.
Note: You only need to calibrate this adjustment method can get a precise voltage value across the entire voltage range, this feature is designed to meet your requirements and design a higher accuracy, ease of use.
Applications:
This module can be applied to fields in the input voltage is higher than the buck output voltage, such as batteries, power transformers, DIY adjustable power supply, 24V car T of the power equipment industry buck, 12V switch 3.3V, 12V turn 5V, 24V turn 5V, 24V switch 12V, 36V switch 24V and so on.
