1. Input voltage range: DC 3.2V to 40V (The input voltage must be 1.5V higher than the voltage to be output. It cannot be boosted.) Features:

2, the output voltage range: DC 1.25V to 35V voltage continuously adjustable, high efficiency (maximum 92%) maximum output current is 3A.

Module usage:

1. Connect to the power supply (3-40V), the power indicator light is on, and the module works normally.

2. Adjust the blue potentiometer knob (usually rotate clockwise to boost, counterclockwise Turn to buck) and use a multimeter to monitor the output voltage to the required voltage.

requires attention:

1. Long-term work is recommended to use current within 2.5A, plus Hot film (10W or more output); because it is a step-down module, in order to ensure the output is stable Please keep a minimum 1.5V differential pressure.

Applications:

1. On-board regulated power supply, only need to connect the input end of this module to the cigarette lighter of the car, you can adjust the potentiometer, the output voltage can be adjusted at 1.25-30V, charge your mobile phone, MP3, MP4, PSP, etc. Many devices are powered, which is very simple and convenient.

2. Power the electronic equipment. When the equipment needs 3-35V power supply and the corresponding voltage power supply is used, this module can conveniently adjust the voltage to the required voltage to solve the problem.

3. System working voltage test, this module can be used to debug the working voltage range of various voltage test systems, which is very convenient and convenient.
