Description:

Digital Voltmeter (0-100V) and Ammeter (10A) Dual LED Voltage Current Measurement Module

Are you in search of a reliable and versatile solution for real-time voltage and current monitoring? Look no further. Our Digital Voltmeter Ammeter is designed for accuracy, ease of use, and wide-ranging compatibility.

This digital panel offers precision with the capability to measure voltage up to 100 VDC and current from 1-50A, ensuring you get the data you need. Whether you're using it for your motorcycle, car, or any other DC voltage monitoring applications, this tool is a perfect fit. The dual LED display features red for voltage and blue for current, providing you with easy-to-read data even in low-light environments.

For those who require precise measurements, this device includes built-in calibration potentiometers for fine-tuning. Operating with a versatile input range of 4.5V to 30V DC, this voltmeter ammeter is suitable for various systems and applications. Plus, it provides quick data updates with a refresh rate of about 500 MS/time, keeping you informed in real-time.

Wiring of the Voltmeter Ammeter:

• Black line (thin): vacant or buck circuit (module) Negative.
• Red line (thin): power supply Positive.
• Black line (thick): COM, common measuring. 
• Red line (thick): PW+, measuring terminal voltage input positive.
• Yellow line (thick): IN+, current input Positive.

Features:

• Dual Display: Real-time, simultaneous display of voltage and current

• Compact & Easy to Install: Fits in panel cutouts or project boxes

• Integrated Shunt Resistor: Supports up to 10A current measurement with included shunt (external or onboard depending on version)

• 4-Wire or 3-Wire Operation:

• 4-Wire mode: Separate power and measurement for high accuracy.

• 3-Wire mode: Shared power and voltage input (simple setups)

• Reverse Polarity Protection: Prevents damage from incorrect wiring (varies by model)

• Color-Coded LED: Clear and bright digits for easy readability.

Applications:

• Digital Voltmeter is used to know the actual voltage of different components.
• DVM is widely used to check if there is power in the circuit, such as the main outlet.
• Knowing the voltage across a circuit, the current can be calculated.

• Battery monitoring (e.g., for lithium or lead-acid systems)

• DC power supply readout

• Solar panel and charge controller monitoring

• Robotics and DIY electronics projects

• Automotive voltage/current monitoring

• Lab bench testing and diagnostics
