Product information

Description

The F&F DMV-3T is a high-precision 3-phase digital modular voltmeter engineered for continuous voltage monitoring in AC electrical networks. Utilizing advanced TrueRMS measurement technology, this device ensures accurate readings even in environments with non-sinusoidal waveforms. Designed for seamless integration into electrical distribution panels, it provides real-time data on voltage levels across three phases, supporting both industrial and residential infrastructure requirements.

Advantages

The primary benefit of the DMV-3T is its high measurement accuracy of 0.5%, which allows for precise monitoring of power quality. The TrueRMS technology ensures that the voltmeter provides reliable results regardless of the signal shape, making it superior to standard average-responding meters. Its modular design and DIN-rail mounting capability facilitate quick and space-efficient installation in standard distribution boards. The clear digital display offers immediate visibility of voltage parameters, enabling rapid diagnostics and maintenance of electrical systems.

Suitable for

Monitoring voltage in 3-phase industrial power networks
Residential electrical distribution board management
Verification of power supply stability for sensitive equipment
Preventive maintenance and diagnostics of electrical installations

When it may not be suitable

This device is specifically calibrated for a voltage range of 100-300V AC and is not suitable for monitoring systems operating outside these parameters, such as high-voltage industrial grids or low-voltage DC circuits. It is intended for indoor use within standard electrical enclosures and should not be exposed to harsh outdoor environmental conditions without appropriate protection.

Key specifications

Measurement type: TrueRMS
Voltage range: 100-300V AC
Accuracy: 0.5%
Mounting: DIN-rail (TH35)
Phase configuration: 3-phase

How to use

The voltmeter is designed for installation on a standard TH35 DIN-rail within an electrical distribution cabinet. Connection should be performed by a qualified electrician in accordance with local electrical safety regulations. The input terminals must be connected to the respective phases of the AC network. Once powered, the device automatically initiates measurement and displays the voltage values for each phase on the integrated digital screen, requiring no further calibration or manual intervention for standard operation.

What to consider before purchase

Ensure your network voltage falls within the 100-300V AC range
Verify available space on the DIN-rail in your distribution board
Confirm that the installation environment meets the required safety standards for electrical equipment

Usage recommendations

Regularly inspect the display and connections during routine maintenance to ensure the device remains securely mounted and that the electrical contacts are free from oxidation or loose wiring.
