Digital Voltage Meter – 2.7-30V – Blue Display – 2 Wire
Original price was: R49,00.R35,00Current price is: R35,00.
Particularly in situations of power outages and people constructing their own customized lead acid and lithium battery banks, the Mini 2-wire Volt Meter (2.7 – 30 VDC) can be useful. This convenient display is commonly used by RC enthusiasts to monitor batteries, but it is also suitable for placement on breadboards or enclosures. With only two wires needed to both power and measure, connect the red wire to the positive supply and the black wire to negative ground. The microcontroller within the display reads the voltage, compares it to a stable reference, and presents the voltage with a precision of 0.1V on a 3-digit 7-segment display. It operates from 2.7V to 30V, making it suitable for most electronic projects. The display’s green LED is bright and readable, and mounting tabs make it simple to attach to any box or plate. The meter consumes 3-4mA of power to operate the microcontroller and display.
