1. Input voltage range: DC 3.2V to 40V (The input voltage must be 1.5V higher than the output voltage . It cannot be boosted ) Features:
2, the output voltage range: DC 1.25V to 35V voltage is continuously adjustable, high efficiency (up to 9 can be 2 %), output current up to 3A.
Module usage method:
1. Connect the power supply (3-40V), the power indicator light is on, and the module works normally.
2. Adjust the blue potentiometer knob (generally turn clockwise to boost, counterclockwise
Step-down) and monitor the output voltage with a multimeter until it reaches the required voltage.
requires attention:
1. It is recommended to use the current within 2.5A for long-term work , and add the scattered
Heater (output above 10W) ; because it is a step-down module, in order to ensure stable output
Please keep the minimum voltage difference of 1.5V .
Applications:
1. Vehicle-mounted stabilized power supply, you only need to connect the input terminal of this module to the car cigarette lighter to supply power, you can adjust the potentiometer, and the output voltage can be adjusted at 1.25-30V to charge your mobile phone, MP3, MP4, PSP, etc. Many devices are powered, very simple and convenient.
2. Supply power to electronic equipment. When the equipment needs 3-35V power supply and the corresponding voltage power supply in hand, this module can be used to conveniently adjust the voltage to the required voltage to solve the problem.
3. System working voltage test. This module can be used to debug various voltage test system working voltage ranges when doing projects, which is very easy and convenient.
