Digital voltage indicator DMV-3, three-phase, measurement range 100÷300V, 3 modules

Digital Voltage Indicator DMV-3 – Precise Measurement in Three-Phase Installations

The Digital Voltage Indicator DMV-3 is a reliable tool for continuous voltage monitoring in three-phase networks. The device is designed for both professional applications and users requiring accurate readings of electrical parameters. DIN 35mm rail mounting ensures convenient and quick installation in switchboards.

Functionality and Application

The DMV-3 indicator is used to continuously read voltage values in three-phase networks. Equipped with a clear, backlit LED display, it allows easy reading even in low light conditions. Accuracy class 1 guarantees precise measurements, which is crucial for the correct analysis of the electrical installation's operation. The device is legalized, which confirms its compliance with applicable standards and enables its use in applications requiring metrological supervision.

Construction and Characteristic Features

DMV-3 is a compact device with a width of 3 modules (52.5 mm), allowing for efficient use of space in the switchboard. Power is supplied directly from the measured AC circuit (100÷265 V), eliminating the need for additional power supplies. Made of high-quality materials, it ensures durability and resistance to environmental conditions. Screw terminals 4.0 mm² with a tightening torque of 0.5 Nm guarantee a secure connection of wires. The device's power consumption is only 4W, minimizing its impact on the operation of the installation. It is worth noting the possibility of legalizing the device – an important feature for many industrial and commercial applications.
