Multifunctional digital network parameter meter DMM-4T, panel mount 96x96mm

Multifunctional Digital Multimeter – Precise Measurement of Network Parameters

This three-phase digital indicator DMM-4T is an indispensable tool for monitoring electrical network parameters. The device is designed for both professional applications and for individuals requiring accurate measurements in home installations. Its panel format (96x96mm) allows for convenient mounting on distribution boards.

Functionality and Application

DMM-4T offers a comprehensive measurement of key parameters of three-phase electrical networks. It enables independent measurement of current in each of the three phases, both direct (up to 5A) and indirect using standard current transformers (in the range of 1÷9000/5A). Additionally, it measures phase and line-to-line voltages in the range of 12÷400V AC and phase frequency (10÷100 Hz). The indicator displays the user-selected phase or line-to-line voltage and frequency, providing full control over the condition of the installation.

Construction and Mounting

The device is characterized by a clear, digital LED display with five digits (digit height 9 mm), ensuring easy reading even in difficult lighting conditions. Mounting is done with screws, and the mounting hole dimensions are 92 mm x 92 mm. The solid construction and IP20 protection degree guarantee reliable operation in industrial and home environments. The device's power consumption is 3 VA, and the operating temperature is in the range of -5÷50°C. The connection is made using screw terminals 1.5 mm² with a tightening torque of 0.4 Nm.

Precision and Accuracy

The DMM-4T multimeter provides an accuracy level of 1%, making it an ideal tool for professionals involved in the service and diagnostics of electrical installations. The ability to scale the indicator to appropriate current transformer values allows you to adapt the device to the specific requirements of a given application. This allows for precise monitoring of loads on all three phases and control over the condition of the electrical network.
