Description:
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 -effective, and simple to use.
This version of the LM2577 DC-DC step-up (boost) power supply module includes the very useful addition of an integrated digital voltage meter. Together with its high-precision multi-turn potentiometer, this means any desired output voltage within its supply range can be set without the need for an external voltage meter. The module also boasts a very high operating range with a DC input supply range of 3 – 34V and an adjustable output range of 4 – 35V.
Specifications:
- Operating Temperature (°C): -40 to 90
- Voltmeter Range(V): 0 to 40
- Max. Output Current (A): 3
- Output Voltage(V):4 ~ 35
Features:
- Multiple output regulator.
- One button to switch the input and output voltage display.
- Power-down memory function.
- Press the button for 3 seconds can turn OFF/ON the LED display.
- With wiring terminal.
- When adjusting the blue potentiometer, please use a multimeter to monitor the voltage
- Rotating Clockwise can raise the voltage while rotating counterclockwise could lower the voltage
- 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.
