LM2577 3A DC-DC Step UP LED Voltmeter 3-34 to 4-35V Adjustable Boost Converter module

The LM2577 3A DC-DC Step UP LED Voltmeter 3-34 to 4-35V Adjustable Boost Converter module operates as a 150 KHz fixed frequency PWM buck (step-down) DC/DC module. With minimal external components required, these regulators offer cost-effectiveness and ease of use.

This version of the LM2577 DC-DC step-up (boost) power supply module features an integrated digital voltage meter, providing added convenience.

Alongside its high precision multi-turn potentiometer, this feature enables users to set any desired output voltage within its supply range without the need for an external voltage meter. Additionally, the module offers a broad operating range, with a DC input supply range spanning from 3 to 34V and an adjustable output range of 4 to 35V.

Features:

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.

Package Includes:

1 x LM2577 3A DC-DC Step UP Voltmeter.
