Digital Voltage Meter – 2.7-30V – Blue Display – 2 Wire

Original price was: R49,00.Current 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.

Description

1. The wiring of this voltmeter is simple. The conventional two wires are used, the red is connected to the positive, the black is connected to the negative, and the reverse connection is protected.
2. Conventionally, no external working power supply is required, and the measuring voltage can be directly operated. The measuring voltage range is two-wire 2.50-30V.
3. Wide voltage operation, with a 2.50V low voltage and safe operation up to 30V, more than 30V may damaged the meter.
4. When measuring voltages below 10V, two digits are displayed after the decimal point; when measuring voltages above 10V, one digit is displayed after the decimal point.
