Description

It is a LM2577 3A DC-DC Step UP LED Voltmeter 3-34 to 4-35V. The LM2577 3A DC-DC Step UP LED Voltmeter 3-34 to 4-35V Adjustable Boost Converter module is a 150 KHz fixed frequency PWM buck (step-down) DC/DC module. Requiring a minimum number of external components, these regulators are cost-effective and are simple to use.

This version of LM2577 DC-DC step-up (boost) power supply module includes the very useful addition of an integrated digital voltage meter.

Features of LM2577 3A DC-DC Step UP LED Voltmeter 3-34 to 4-35V:

1. Multiple output regulator.
2. One button to switch input and output voltage display.
3. Power-down memory function.
4. Press the button for 3 seconds can turn OFF/ON the LED display.
5. With wiring terminal.
6. When adjusting the blue potentiometer, please use a multimeter to monitor the voltage
7. Rotating Clockwise can raise the voltage while rotating  counterclockwise could lower the voltage
8. When the module output voltage cannot be adjusted, ( the output voltage is always equal to the input voltage ) please adjust the potentiometer counterclockwise 20 laps (20 turns) or more till it works.
