Digital current value indicator, single-phase DMA-1 Imax=20A 3 modules

Digital Current Meter – Precise Measurement in Your Installation

This digital, single-phase current meter DMA-1 is a reliable tool for continuous monitoring of the electrical circuit load. The device is designed for both home and professional electrical installations. It allows for direct reading of the current value, eliminating the need for additional current transformers in the range up to 20A.

Functionality and application

The DMA-1 meter is perfect for situations where constant monitoring of current consumption is crucial. Thanks to the digital measurement system, it provides high reading accuracy, and the backlit scale makes it easy to read even in low light conditions. It is particularly useful in industrial installations where distorted waveforms occur – the True RMS version guarantees correct indications even in such conditions. Mounting is done on a standard DIN rail, ensuring easy integration with existing infrastructure.

Construction and characteristic features

The DMA-1 meter is characterized by a compact design, occupying only 3 modules on the DIN rail (52.5 mm wide). Made of high-quality materials, it ensures durability and reliability. Screw terminals with a cross-section of 4.0 mm² guarantee a secure connection of the wires, and the tightening torque of 0.5 Nm ensures optimal contact. The device's power consumption is only 4W. It is worth noting the wide range of indications – from 25 to 1000 A (using transformers) and from 0 to 20 A with direct measurement. Accuracy class 1 confirms the precision of measurements. The device is legalized, which is important in applications requiring compliance with legal standards.

Additionally:

• Direct measurement: Possibility of measuring current without the need for current transformers (up to 20A).
• True RMS: Correct indications for distorted waveforms.
• DIN rail mounting: Quick and easy mounting in standard distribution boards.
• Backlit scale: Readable display even in dark rooms.
• Wide measurement range: Flexibility of use in various installations.
• Legalization: Compliance with legal requirements and possibility of use in commercial applications.
