Buck Boost Power Supply Module USB Voltmeter Tester 5V Multi-Fun
- ãMulti-FunctionãThis is a multi-function voltage-ammeter. It can work in 3 modes: Power Supply Mode, Voltage-Ammeter Mode, PWM Mode. the main function is to output voltage as a constant voltage constant current source and measure the voltage, current, capacity, energy, time, power, temperature, it also supports fast charge protocol and output PWM signal. it's the best choice for you. "li" ãFlexible Color Display DesignãAdopt 1.44 Inch USB Full-Color LCD Display, 5-digit High Precision Display, High Resolution, Foreground and Background colors are switched alternately, with 64 colors options to choose. support 360° screen rotation to meet any angle reading, you can rotate the screen by pressing the button corresponding to the horizontal menu bar. "li" ãPER ModesãThis product can be used as a buck-boost power supply with over-voltage / over-current / over-power / over-temperature / under-voltage protection. it with constant current function, can charge small rechargeable batteries within 0.6V-30V 15W. it also with constant current function, can directly drive 0.6-30V, 0-15W LED lights "li" ãVAH ModesãIt can measure voltage and current as multimeter,can measure power,capacity,energy,time,used for battery charge and discharge measurement, high-precision coulomb meter and so on. "li" ãPWM Modesãit can be used as a square wave signal generator, pulse signal generator, generate square wave signal for controlling DC motor or stepper motor driver; used for servo motor, stepper motor,electric gripper,replacing PLC pulse and so on.
