The F&F DMA-1 is a high-precision single-phase digital ammeter engineered for direct current measurement within the 0-20A range. Designed for seamless integration into electrical distribution boards, this device features a compact modular housing suitable for standard DIN rail mounting. It provides reliable, real-time monitoring of electrical current, making it an essential component for maintaining safety and efficiency in both residential and industrial power systems.
Advantages
The primary benefit of the F&F DMA-1 is its ability to deliver accurate, real-time current readings, allowing users to monitor power consumption and detect potential electrical issues immediately. Its modular design simplifies the installation process, as it fits perfectly onto standard DIN rails alongside other protective equipment. The digital display ensures clear readability, eliminating the inaccuracies often associated with traditional analog gauges. Furthermore, the robust construction ensures long-term operational stability in various environmental conditions.
Suitable for
- Monitoring current consumption in residential electrical panels
- Industrial machinery power usage tracking
- Energy management systems in commercial buildings
- Verification of electrical load in single-phase circuits
This device is not suitable for measuring currents exceeding 20A, as direct connection to higher loads may cause damage to the internal circuitry. It is also not intended for use in high-voltage industrial systems beyond the specified single-phase parameters or in environments with extreme moisture or corrosive gases that could compromise the digital display.
Key specifications
- Measurement range: 0-20A
- System type: Single-phase
- Mounting type: DIN rail (TH-35)
- Display type: Digital
- Design: Modular
To use the F&F DMA-1, ensure the power supply is disconnected before installation. Mount the device onto a standard DIN rail within your distribution board. Connect the phase conductor in series with the ammeter terminals according to the provided wiring diagram. Once securely installed and verified, restore power to the circuit. The digital display will automatically activate and begin showing the current flow in real-time.
What to consider before purchase
- Verify that your circuit current does not exceed the 20A limit
- Ensure there is sufficient space on your DIN rail for a modular unit
- Confirm that the system is a single-phase configuration
For optimal performance and safety, ensure all electrical connections are tightened to the manufacturer's specifications and that the device is installed by a qualified electrician in accordance with local electrical regulations.
