Multifunctional digital network parameter measurement multimeter with Modbus RTU communication DMM-5T-2

Multifunctional power network parameter analyzer – precise measurement and monitoring

This multifunctional digital multimeter DMM-5T-2 is an advanced device designed for comprehensive analysis of electrical network quality. It will work in both single-phase and three-phase installations, offering precise measurement of key parameters. Thanks to Modbus RTU communication, it enables remote data reading, which is particularly useful in monitoring and automation systems.

Versatile application and measurement accuracy

The device measures phase and interphase voltages and currents, frequency, active, reactive and apparent power, power factor and phase angle. It provides high measurement accuracy – active energy at class 0.5S level (IEC62053-22), and voltage, current and frequency at 0.2% level. This makes it indispensable in diagnosing electrical installations, optimizing energy consumption and detecting irregularities in network operation.

Design and functionality for professionals

The DMM-5T-2 multimeter has been designed for easy installation and operation. The housing with dimensions of 96 x 96 x 62 mm fits into standard mounting holes (92 x 92 mm) and is adapted for mounting on a DIN rail. It has an IP54 protection class on the front, which ensures resistance to dust and splashes. Communication is via an RS-485 port with Modbus RTU protocol support (configurable transmission speed, parity and stop bits). Two pulse outputs further expand the device's application possibilities. The device operates in a temperature range from 25°C to 55°C, which guarantees reliability in various environmental conditions.

Key product features:

• Measurement of a wide range of parameters: voltage up to 400V AC, current up to 5A (depending on current transformers), active/reactive/apparent power, power factor, phase angle, frequency.
• Modbus RTU communication: enables integration with SCADA systems and building automation.
• High accuracy: class 0.5S for active energy, 0.2% for voltage, current and frequency.
• Versatility: possibility of measurement in single-phase (1P2W), three-phase (3P3W) and four-wire (3P4W) networks.
• Solid construction: UL94 – V0 housing providing fire resistance and a high degree of IP54 protection.
• Pulse outputs: facilitate data logging and integration with other systems.
• Application: electrical network parameter analyzer
• Power supply: battery/mains

The DMM-5T-2 multimeter is a reliable tool for electrical installers, service technicians and anyone responsible for monitoring the quality of electrical energy. Its versatility and precision make it an ideal solution for both industrial, commercial and residential applications.
