1pc DC-DC Buck Converter Voltage Regulator Step Down Module 5A 4.0V38V to 1.25V36V Adjustable

1、This is a 5A high power high efficiency DC-DC buck module with low ripple and converts 4.0V~38V to 1.25V~36V

2、The voltmeter on board can be self calibrated; using more advanced voltage microprocessor, voltmeter error is ±0.05V, measuring range of 0~40V

3、Input and output have screw terminals for convenient connection even with no soldering iron, and keep solder pad for soldering connection

4、It supports overheating protection and short circuit protection function

5、Comes with heat sink for better heat dissipation, and several standoffs and nuts

Features:

This is a 5A high power high efficiency DC-DC buck module with low ripple and converts 4.0V~38V to 1.25V~36V.

The voltmeter on board can be self calibrated; using more advanced voltage microprocessor, voltmeter error is ±0.05V, measuring range of 0~40V.

Input and output have screw terminals for convenient connection even with no soldering iron, and keep solder pad for soldering connection.

It supports overheating protection and short circuit protection function.

Comes with heat sink for better heat dissipation, and several standoffs and nuts.

Specifications:

Input Voltage: 4.0V~38V (input voltage should be at least 1.5V higher than the output voltage)

Output Voltage: 1.25V~36V (continuously adjustable)

Output Current: Max. 5A(4.5A or less is suggested)

Max. Output Power: 75W

Max. Efficiency: 96% (Efficiency is related to input/output voltage, current and voltage difference)

Load Regulation S(I): ≤0.8% Voltage Regulation S(u): ≤0.8%

Size: 60*36*18mm/2.36*1.41*0.7"

Voltmeter Self-calibration Instruction:

1.

When the voltmeter on board displays output voltage, press and hold the

right button for 2 seconds to enter output voltage regulation mode, and

the voltmeter display and output voltage indicator light synchronously

flash.Similarly, when the voltmeter on board displays input voltage,

press and hold the right button for 2 seconds to enter input voltage

regulation mode, and the voltmeter display and input voltage indicator

light synchronously flash.

2. Press the right button to increase

voltage value, and left button to reduce voltage value.Due to a unit of

voltage is less than 0.1 V, so you need to press button for 1 time~5

times to see the voltage value changes 0.1V.

3. After voltage

adjustment, press and hold the right button for 2 seconds then release

to exit voltage calibration mode. All the parameters set up will be

automatically saved if power failure.

Note: To ensure that the voltage meter accuracy, please make sure that the input voltage is above 4.5V

Package Includes:
