Digital Voltage Indicator DMV-1 – precise measurement and control

The DMV-1 power supply indicator light is a reliable device designed for continuous monitoring of voltage in single-phase networks. DIN rail mounted, it occupies 3 modules, making it an ideal solution for both home and industrial switchboards. The device is particularly useful wherever constant monitoring of power parameters is critical.

Functionality and application

DMV-1 is used to visualize voltage values in the range of 100 to 300V AC. Equipped with a backlit measuring scale, it provides a clear reading even in low light conditions. Its DIN rail-based design simplifies installation and integration with existing electrical infrastructure. The device is legalized, which confirms its accuracy and compliance with applicable standards. It is worth noting that the DMV-1 model does not require current transformers for measurement.

Advantages for installers and users

• Quick installation: Compact dimensions (3 modules) and DIN rail mounting significantly speed up installation.
• Clear display: Backlit LED scale provides a clear reading even in difficult conditions.
• Measurement accuracy: Accuracy class 1 guarantees precise voltage readings.
• Versatility: Suitable for both home and industrial applications.
• Safety: Device legalization confirms its compliance with standards and ensures measurement reliability.
• Low power consumption: Energy consumption at 4W minimizes the impact on the overall load of the installation.
• True RMS: True RMS version (available as DMV-1RMS) provides accurate voltage measurement even with distorted waveforms, typical of industrial installations with non-linear loads.

This device not only indicates the voltage value, but also constitutes an element of visual control of the electrical network status, allowing for quick identification of potential problems and preventing failures. Therefore, DMV-1 is an investment in the safety and reliability of the electrical installation.
