Product information

Description

The FF DMA-3 20A TrueRMS is a high-precision digital 3-phase modular ammeter engineered for accurate current monitoring in electrical distribution systems. This device utilizes TrueRMS technology to ensure reliable measurements even in circuits with non-sinusoidal waveforms, making it an essential tool for both industrial and residential electrical panels. Designed for seamless integration, its compact modular form factor allows for quick and secure mounting on standard DIN rails.

Advantages

The primary benefit of this ammeter is its high measurement accuracy of 0.5%, which provides users with precise data for effective energy management and system diagnostics. By utilizing TrueRMS measurement, the device maintains consistency and reliability across various load types, preventing errors common in standard averaging meters. Its modular design simplifies the installation process within existing distribution boards, saving time and space while providing a clear, real-time visual representation of current consumption across all three phases.

Suitable for

  • Monitoring current in 3-phase industrial electrical systems
  • Residential energy consumption tracking
  • Diagnostic checks in distribution boards
  • Real-time load balancing verification

This device may not be suitable for applications requiring current measurements exceeding 20A, as it is specifically calibrated for the 0-20A range. It is also not intended for use in environments with extreme moisture or high levels of conductive dust without appropriate protective enclosure housing.

Key specifications

  • Measurement range: 0-20A
  • Accuracy: 0.5%
  • Measurement type: TrueRMS
  • Phase compatibility: 3-phase
  • Mounting: DIN rail

To use the FF DMA-3 20A TrueRMS, ensure the device is mounted securely on a standard DIN rail within a distribution board. Connect the current inputs according to the wiring diagram provided by the manufacturer, ensuring that the connections are tight and secure to prevent resistance issues. Once powered, the digital display will provide real-time readings of the current flowing through each phase, allowing for immediate monitoring of the electrical system status.

What to consider before purchase

  • Verify that your system current does not exceed the 20A limit
  • Ensure your distribution board has sufficient DIN rail space
  • Confirm compatibility with your specific 3-phase electrical configuration

Usage recommendations

For optimal performance and safety, ensure that the installation is performed by a qualified electrician in accordance with local electrical regulations and that the device is protected by appropriate circuit breakers.
