Dc-dc adjustable pressure-relief module with voltmeter display with voltage precision calibration


Module highlights:

- comfortable heart price, intelligent, humanized design, with high value for money!

- plate-mounted voltmeters, which can be self-calibrated, will never have the problem of inaccuracy!

Module performance and characteristics:

●With voltmeter display and voltmeter self - calibration.A more advanced voltage microprocessor was adopted, with voltage meter error ±0.05 v, measuring range 0~40 v. (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 have an indicator indicating which voltage is being measured, and to save settings, even if power is out of power.

●The voltmeter can be closed and can be easily implemented when you touch the left button when you don't need it.

●With terminal, without soldering iron can be easily used, and keep the line connection point.

●Input voltage 4.0~40 v. (the input voltage shall be 1.5v higher than the output voltage)

●Adjustable output voltage range 1.25 v~37 v continuously adjustable. (input voltage shall be 1.5v higher than output voltage)

●Output current 3a, recommended for use in 2.0a, large current needs to strengthen heat dissipation.

●Output power 20 w, more than 15 w please strengthen heat dissipation.

●Conversion efficiency at an average of 88% (efficiency is related to input, output voltage, current, differential voltage)

●With back-up protection, back-up does not burn

●Superheat protection and short circuit protection

●Size 6.6x3.6x14cm (long x wide x high)

●Weight: 23g



Scope of application:

This module can be applied in pressure-relief field where input voltage is higher than output voltage,Such as batteries、Power transformers、Diy adjustable steady voltage power supply、24v car pen meter power supply、Pressure relief for industrial equipment、12v to 3.3v,12v to 5v, 24v to 5v,24v to 12v,36v to 24v et al.



Self-calibration method for plate-borne voltmeters:

- when a panel-mounted voltmeter displays the output voltage, it loosens after a long press on the right button for 2 seconds, and the voltmeter and the output voltage indicator "out" flicker simultaneously, entering the output voltage adjustment mode;Similarly, when the voltmeter displays the input voltage, it loosens after a long press on the right button for 2 seconds, and the voltmeter and the input voltage indicator "in" flicker simultaneously, entering the input voltage adjustment mode;

- touch the right button with a unit of higher voltage, touch the left button with a unit of lower voltage;Since a unit of voltage is less than 0.1v, you need to press 1-5 times to see the voltmeter change 0.1v. the specific continuous button depends on the current voltage, and the higher the current voltage is, the fewer times it moves;

- after voltage adjustment is completed, release after long press rig
