Voltmeter&Ammeter 100V 100A With Shunt

Overview of 100V 100A Voltmeter and Ammeter with Shunt

A 100V 100A voltmeter and ammeter is a dual measurement device designed to monitor both voltage and current in DC circuits. These instruments are particularly useful in various applications, including battery management systems, solar power systems, and other electrical setups where precise measurements are crucial.

Key Features

• Measurement Range: These devices can measure DC voltage up to 100V and current up to 100A. They typically require an external shunt to accurately measure high currents 1.
• Display: Most models feature a dual LED display, allowing users to view both voltage and current simultaneously. The displays often come in different colors, such as blue and red, for easy readability.
• Precision: The voltmeters and ammeters usually offer auto-ranging capabilities with a precision of 0.01V for voltage and 0.01A for current. The voltage tolerance is often around ±0.1%, while current accuracy can be about ±1% 1.
• Shunt Specifications: A heavy-duty external shunt is included, which is essential for measuring currents up to 100A. For example, a common shunt resistance is 75mΩ, which allows for accurate current readings.

Applications

These voltmeter and ammeter combinations are widely used in:

• Renewable energy systems (like solar panels)
• Battery monitoring systems
• Electrical testing and diagnostics
• DIY electronics projects

Conclusion

A 100V 100A voltmeter and ammeter with shunt is an essential tool for anyone needing to monitor electrical parameters accurately. With features like dual displays, high precision, and the ability to handle significant current loads, these devices are invaluable in both professional and hobbyist settings.
