DC-DC Buck Module LM2596 Upgraded Version 3A Adjustable Band - Red
Feature: 1£¬ DC input voltage range: 3.2V to 46V (input voltage to the output voltage must be higher than 1.5V. Cannot boost) 2£¬ the output voltage range: 1.25V to 35V DC voltage continuously adjustable£¬ high efficiency (up to 92%) the maximum output current is 3A. 3£¬ the input end with reverse connection protection£¬ positive and negative reverse module will not burn. Usage: 1£¬ access to power (3.2V-40V)£¬ the power indicator light£¬ the module is working properly. 2£¬ adjust the blue potentiometer knob (generally clockwise boost£¬ counterclockwise Buck) and the multimeter is used to monitor the output voltage to the voltage you want. Attention: Long time work is recommended in the current use of less than 2.5A£¬ plus the heat sink (10W above output); due to the buck module£¬ in order to ensure the output stable£¬ please keep the minimum 1.5V pressure difference. Application: 1£¬ vehicle regulated power supply£¬ only need the module input terminal is connected to the car cigarette mouth power supply can adjust potentiometer£¬ the output voltage can be in 1.25-30V can be adjusted arbitrarily£¬ for your mobile phone£¬ MP3£¬ MP4£¬ PSP charging many power supply equipment£¬ very simple and convenient. 2£¬ to the electronic equipment power supply£¬ when the equipment needs 3-35V power supply and the corresponding voltage power supply£¬ with this module can be easily transferred to the voltage required to solve the problem. 3£¬ the system operating voltage test£¬ the project can use this module to debug a variety of voltage testing system operating voltage range£¬ very easy and convenient.
