Digital voltage indicator, single-phase DMV-1 true RMS measurement range 100÷300V 3 modules DMV1RMS

Digital Voltage Indicator DMV-1 True RMS – Precise Measurement in Your Installation

This DMV-1 True RMS digital voltage indicator is a reliable tool for monitoring voltage in single-phase networks. The device is designed for both professional and demanding end-users who want full control over the electrical parameters in their home or business. Mounting on a DIN TH-35 rail ensures convenient and quick installation in electrical distribution boards.

Practical Application and Functionality

The DMV-1 indicator is used to continuously read the value of phase voltage. Its construction based on a measurement circuit, which simultaneously powers the device, eliminates the need for additional power sources. Equipped with a True RMS value converter, it provides accurate measurements even with distorted waveforms, which is particularly important when powering non-linear devices such as switch-mode power supplies or motor controllers. A clear, 3-digit LED display with a digit height of 10 mm guarantees easy reading of indications even in difficult lighting conditions.

Construction Features and Mounting

The device occupies 3 modules on the DIN rail, allowing for compact placement in distribution cabinets. Screw terminals with a cross-section of 4.0 mm² provide a secure connection of wires, and a tightening torque of 0.5 Nm guarantees connection stability. The indicator meets the requirements of metrological approval, which confirms the accuracy and reliability of measurements. The device's power consumption is only 4W, which minimizes its impact on the overall energy consumption of the installation. The indication range of 100÷300 V AC covers most standard network voltages. Accuracy class 1 ensures precise measurements – important for both professionals performing control measurements and users who care about the correct operation of their devices.
