PEMENOL USB Step Up/Down Power Supply Regulator Module 3.5V-12V to 1.0V-24V 2-3W, Adjustable Boost Buck Voltage Converter Digital Display Voltmeter Ammeter Battery Capacity Tester

* Power System (PER)：There are 3 input interfaces, USB, micro USB, Type-C, input any interface, under the power system (PER), you can output an adjustable voltage from 1.0V to 24V, power 2-3W. Note: It is a low power supply, please do not exceed the maximum output power. * Multimeter System (VAH): The CNC USB power supply regulator module can measure voltage and current, test power, capacity, and time just like a multimeter. It can also test the current ambient temperature. Temperature range -20℃~70℃ * With multiple protection functions： When the voltage﹤0.8V, there will be under-voltage protection(LVP); when the input current﹥2A, there will be overcurrent protection(OCP); When using over power, there will be over-power protection(OPP). After protection, the output will be automatically turned off, the LCD backlight will flash, and the corresponding protection will be displayed(LVP, OCP, OPP) * Small size, easy to carry：small size 78*28*17mm with Anti-extrusion packaging box.
