DC-DC adjustable power supply module, LM2596 voltage regulator module, with the voltmeter display

Product Description

DC-DC adjustable power supply module, LM2596 voltage regulator module, with the voltmeter display

The input and output voltage can be displayed alternately; State boot-up can be freely defined; With the Off button, lower power consumption.
Output ON / 0FF operating condition, high electrical level means output out, low level means output on. (Note: High Level (3.3V), Current Maximum Output 5mA.)
There are three operating modes of this product: voltage output in mode, live input mode and alternate mode.
Start refers to the voltage output mode by default, LED indicator off; Print buttom once to switch to the input voltage mode, the LED indicator; Press the new button, input voltage and output alternately display for 3s, then press the button again, switch to the output output display mode.
There are also the other two modes, which are memory modes and interrupt the working mode.

1)Product description

Input voltage range: 4.5-28 v (28 v to limit the highest voltage)

Output voltage range: 1.3 V – 25 V (decompression mode, input output must be greater than 2 V above)

Output current: 1.5 A continuous output

Output power: the maximum 15 w

Ripple frequency: 150 KHZ
Grain wave peak: 100 mv
Size: 62 mm * 26 mm * 14 mm
Voltmeter precision: ± 5 ‰
Static power: 20 ma (and input voltage output voltage and digital tube color is closely related to the actual current will exist deviation)

IN + : input positive/IN – : input negative
OUT + : output positive/OUT – : output negative

2)Features:

1: input/output voltage can alternate display.

2: boot state can customize.

3: a key shutdown function, reduce power consumption.

4: ON / OFF output work condition, high level representative close output, low level representative open output.
Note: high level (3.3 V) the highest output 5 mA current.

3)Work mode explanation:

Output voltage mode: the default boot for output voltage mode display, LED light go out;
