3-phase energy consumption meters with network parameter analysis DEC-3MP 004804062

Three-phase energy meter with network parameter analysis

This advanced electricity meter, designed for three-phase systems, offers precise energy consumption measurement and detailed network parameter analysis. It is indispensable in both industrial installations and commercial buildings where energy consumption control is crucial. The device allows for monitoring and optimizing energy use, which translates to cost reduction and increased energy efficiency.

Construction features and functionality

The DEC-3MP meter is a direct-connected energy meter designed to indicate and record consumed electrical energy. Its direct measurement design eliminates the need for additional current transformers, simplifying installation and reducing installation costs. Communication is via an RS-485 interface, enabling remote data reading and integration with energy management systems. The meter has a counter tamper protection, ensuring the integrity of the measurement data. Additionally, it indicates energy consumption by flashing LEDs – 800 pulses per kWh for active energy and 800 pulses per kvarh for reactive energy.

Application and benefits

The device finds application in a wide range of electrical installations:

• Energy consumption monitoring: Precise measurement of active and reactive energy consumption allows for accurate cost analysis and identification of areas requiring optimization.
• Network parameter analysis: Measures voltage, current, active and reactive power, and power factor (cos φ) for each phase, providing comprehensive information about the state of the power supply network.
• Remote data reading: The RS-485 interface enables remote reading of meter indications and integration with monitoring and energy management systems (Modbus RTU).
• Protection against manipulation: Counter tamper protection ensures the reliability of measurement data.
• Fast problem identification: Monitoring network parameters allows for early detection of irregularities and prevention of failures.

The DEC-3MP meter is characterized by accuracy class B, which guarantees precise measurements in accordance with applicable standards. Its width of 7 modules makes it easy to mount in standard electrical panels. The meter's rated current is 5A, and the maximum current is 60A – making it suitable for most industrial and commercial applications. The S0 type pulse output (0…800 Imp/kWh) allows for easy integration with building automation systems or external data logging devices.
