Features With voltmeter: The boost converter module is designed with voltmeter, the error of the voltmeter is ± 0.1V, the measurement range is 5V ~ 35V. Screw Terminals: The input and output of the boost converter module have screw terminals for convenient connection even without soldering iron, and hold the solder pad for soldering connection. Wide Applications: The boost converter module is widely used for storage batteries, power transformers, DIY adjustable regulated power supply, industrial equipment, 9 to 12V, 12V to 18V, 18V to 24V, etc. Output / working current: the maximum output current can be up to 4A; It is recommended that the working current is about 2A and add heat sink if it is more than 2A. Note: If the input voltage is less than 4.5V, the voltmeter will not work and will not be displayed. The input voltage must be at least 1 V higher than the output voltage. Specifications: Input voltage: 4.5V-32V Output voltage: 5V-35V (adjustable) Max. Output current: 4A Efficiency: Package List
