## Overview

The Digital Voltage Current Meter is a dual-display ammeter and voltmeter designed for precise measurement of DC voltage (0-300V) and current (0-100A). It features a wide power supply range, anti-interference capabilities, and is perfect for various applications including solar power systems and electric vehicles. The included shunt ensures safe operation for high currents, making it a reliable choice for professionals.

## Description

Features: Small size, Same time display voltage, current; Using SMT technology; Using "full package" design, with back cover, safe and reliable, dustproof; Using a common Ground wire design, that is, the ground side of the measurement and power supply side of the ground is connected; The voltmeter uses the decimal point automatic movement design; Using a wide power supply range: DC3.5 ~ 30V, power supply reverse will not damage the meter;  Product Specifications: Voltage Meter: Range: 0.0 ~ 300V; Resolution (V): 100V or less: 0.1，100V or more: 1; Impedance:> 1M; Current Meter: Range: 0.0 ~ 99.9A; Resolution (A): 0.1;  Technical Parameters: Supply voltage: DC3.5 ~ 30V (wide range) (Note: the maximum input voltage can not exceed 30V, otherwise there is the risk of damage to the meter) Operating current: <20mA Display mode: 0.39 "LED, voltage - red, current - green Dimensions: 70 × 39 × 40 mm（L*W*H）; Installation : 68 × 38 mm; Measurement rate: ≥500mS / times; Measurement accuracy: 1% (± 2 digit);  Extreme working conditions: Minimum supply voltage: + 3.5V; Maximum supply voltage: + 30V; Working temperature: -10 ~ +65 ℃; Working humidity: 10 ~ 80% (no condensation); Working pressure: 80 ~ 106kPa; Sun exposure: no direct exposure;  Package Included: 1*Digital Voltage Current Meter 1*100A Shunt

## Features

- It‘s a voltmeter for testing DC 0-300V and also an ammeter for testing 0-100A with shunt.
- Using a wide power supply range: DC3.5 ~ 30V, power supply reverse will not damage the meter;
- Anti-interference ability, display refresh speed;
- It's commonly used in solar power systems, battery chargers, DC welding machine, sine wave inverter, electric vehicles, electric vehicles, electric car chargers and other equipment.
- The package contains a shunt, and when the current is greater than 20A, the shunt must be used, otherwise the meter will be damaged. Please refer to the picture for wiring diagram.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Accurate but you MUST use Shunt, unless you solder internally.
*by P***N on July 14, 2021*

Worked fine 1st try easy install doesn't include dash for neg values it will just change direction and values. If calibrations are required two small dials are inside after you remove plastic cover as noted in photos.

### ⭐⭐⭐ Accuracy not fantastic, and won't work without the included shunt
*by M***R on June 28, 2021*

The display is nice, Nice colors. Can read it just fine from a distance.I did a test using a precision reading power supply and load which produced the following results which I verified with additional precision meters;Test values:Voltage input: 15vdcCurrent given the load: 3.33 AmpsDisplay: 14.1 Vdc, 3.5 AmpsThis test demonstrates an accuracy of ~ 5-6%. High on amperage reading, low on voltage reading.According to the diagram this unit should allow you to connect it into the circuit without the supplied shunt. I've found this not to be true at all. If you read the resistance of the current path in the meter, there is no internal shunt and there would have to be in order for it to work without the external shunt. Perhaps a different model has an internal shunt. It's not a problem for me, I can use the external shunt even though I will not be using it with more than 10 amps at 120 vdc.I opened the case and there are current and voltage calibration potentiometers on the circuit board, so it's possible a person could calibrate the unit to read more precisely than it does out of the package. I may look at doing that when I put it in service. The shunt is rated at 100A - 75mv.

### ⭐⭐⭐⭐⭐ Great Meter!
*by K***M on July 20, 2021*

Just what I needed for my new DC power supply.
