Description
DC 0-100V 3-Wire 0.28″ 3-Digit LED Voltmeter Panel Meter
The DC 0-100V 3-Wire Digital Voltmeter is a compact panel-mount voltage meter designed for monitoring DC voltage in batteries, vehicles, power supplies, electronic projects, and other electrical systems. Its bright 0.28-inch LED display makes voltage readings easy to see, even in low-light conditions.
With a 0-100V measurement range, simple three-wire connection, reverse-polarity protection, and an adjustable calibration potentiometer on the back, this mini voltmeter provides a convenient and reliable way to monitor DC voltage.
Key Features
- Wide Measurement Range: Measures DC voltage from 0V to 100V when using the three-wire connection.
- Bright LED Display: Features a clear 0.28-inch red LED display for easy reading.
- Compact Design: Small and lightweight, making it suitable for space-limited installations.
- Three-Wire Connection: Simple wiring makes installation quick and convenient.
- Reverse Polarity Protection: Helps protect the meter from damage caused by incorrect wiring.
- High Accuracy: Provides a resolution of 0.1V with approximately ±0.3% measuring accuracy.
- Adjustable Calibration: A potentiometer on the rear allows the displayed voltage to be adjusted for better accuracy.
- Multiple Applications: Suitable for cars, motorcycles, batteries, power supplies, DIY electronics, and other DC voltage monitoring applications.
Applications
This digital voltmeter can be installed in a variety of electrical and electronic systems, including:
- Car and motorcycle battery monitoring
- DC power supplies
- Solar and battery-powered systems
- Electronic DIY projects
- Control panels
- Industrial equipment
- Embedded and automotive applications
Important Note
When using the two-wire connection, the detection voltage should remain within the specified range. For the three-wire configuration, the meter can measure up to 100V DC. Make sure the operating supply voltage stays within the recommended limits to avoid damaging the meter.
