Features:
★ Module uses high -quality LM2596Chip, high efficiency (the highest efficiency92%), Small heat, can easily bring 3A (short time)aboveCurrent, it is recommended to use the current within 2.5A for a long time, and add the heat sink (output above 10W).
★ This module uses a machine patch to return welding. At the same time, each module is tested for two hours before shipping to ensure high reliability.
★ Since the launch of this module, it has accumulated more than 15,000 pieces, and now it can still maintain a 100%praise rate. It has been tested for a long time and has been well received. It is indeed the best choice for you to buy.
Input 3.2V-40V output 1.25V-35V
Input voltage range:
DC 3.2V -40V (The input voltage must be more than 1.5V higher than the voltage to be output.Can't boost)
Output voltage range:
DC 1.25V -35V voltage can be adjusted continuous,high efficiency(Maximum 92%)The maximum output current is 3A.
Precautions:
Long -term work suggestion is2.5AUse the current inside, add the heat sink (output above 10W); Because it is a antihypertensive module, in order to ensure the stable output, keep the minimum 1.5V pressure difference.
★ This module is a adjustable antihypertensive module that can change the output voltage by adjusting the blue adjustable resistor on the module.The input and output voltage difference is 2V, and the minimum can output 1.25V voltage.
★ The in- (input negative), in+(input positive), out- (output negative), out+(output positive) must be connected correctly, otherwise the module may be damaged.
★ This module does not have short -circuit protection. If it is short -circuited for a long time, the module may cause damage.
Voltage adjustment:
Access power (4-35V), Adjust the blue potentiometer knob (generally rotating the voltage of clockwise, rotating the voltage of clockwise) and using a multimeter to monitor the output voltage to reach the required voltage.
Wiring:
1. Welding, directly welding the power cord in the input (output) port
2. Welding pins can be inserted into the cave plate through the drawing of the welding needle;Or directly weld the PCB after adding the feet.
Application example:
1. In the vehicle voltage voltage power supply, you only need to connect the input terminal of this module to the car cigarette holder to supply power, and you can adjust the potentiometer. The output voltage can be adjusted at 1.25-30V to charging for your mobile phones, MP3, MP4, PSP charging, etc.Many equipment power supply is very simple and convenient.
2. Power on electronic equipment. When the device needs to supply 3-30V power and the corresponding voltage power supply in the hand, use this module to easily adjust the voltage to the required voltage to solve the problem.
3. System work voltage test. When doing projects, you can use this module to debug the voltage range of various voltage test systems, which is very easy and convenient.
