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.
