MID Energy meter

Product catalog summary

Technical Specifications
The document provides detailed technical specifications for energy meters. Key features include a backlighted LCD display, accuracy class B for kWh and class 2 for kVArh, and various test device resolutions depending on the current (6A, 40A, 80A). The meters can handle short-term overcurrent up to 20 times the maximum current for 0.5 seconds and operate within a voltage range of ±20% of the nominal voltage at frequencies of 50/60Hz. They are self-supplied with a voltage circuit consumption of less than 7.5VA and can operate in temperatures ranging from -20°C to +55°C, with storage temperatures from -25°C to +75°C. The humidity tolerance is up to 80% without condensation. The meters are made from self-extinguishing thermoplastic material with protection ratings of IP50 for housing and IP20 for terminals. They comply with standards EN50470-1, EN50470-3, EN62053-23, and EN62053-31.

Tariff and Pulse Outputs
The meters feature an active optoisolated tariff switching input with a voltage range of 80 to 276 Vac/dc, excluding Ethernet models. Pulse outputs are passive optoisolated, with maximum values of 27 Vdc at 27mA and 250 Vac/dc at 100mA for IR models. Pulse values vary by model, with durations of 50 ±2ms for both ON and OFF times.

Ordering Codes and Communication
The document lists various models with different communication capabilities, including RS485 Modbus RTU, Ethernet, and M-Bus, each with specific configurations for single-phase and three-phase systems. Communication modules are detailed on page 9.18.

Dimensions and Wiring Diagrams
Additional technical data includes dimensions and wiring diagrams for different models, highlighting the configurations for three-phase systems with either 3 or 4 wires.

Measurement and Recorded Data
The meters measure instantaneous values such as phase voltage, line current, power factor, apparent power, active power, reactive power, frequency, phase sequence, and power direction. Recorded data includes total active, reactive, and apparent energy, tariff energy counters, resettable partial energy counters, and energy balance.

Other Information
Additional features include monitoring of present tariff, voltage, current, and frequency limits, partial counters, active communication, active S0 pulse, and error conditions. Communication interfaces include RS485, Ethernet, and M-Bus, each with specific standards, protocols, and speed ranges.
