Re Test Three Phase Smart MID Electricity Meter 100A 400V with RS485 Modbus

Product Overview

  The EM513082 is a versatile DIN-rail mountable three-phase four-wire energy meter, part of the EM513082~EM513084 series. Designed for precise energy monitoring in post-payment scenarios, it supports currents up to 100A. It is suitable for various applications, from residential and commercial power distribution to new energy systems like EV charging stations and solar power generation.

Key Features

1. Extensive Measurement Capabilities: Accurately measures a comprehensive set of instantaneous parameters, including voltage, current, active/reactive/apparent power, frequency, and power factor. It also tracks various energy values such as total, forward, and reverse active/reactive energy, as well as multi-tariff T1-T4 data. Supports resettable energy totals and max demand monitoring.

2. User-Friendly Display & Interface: Features a clear, backlit LCD display (6+2 digits) for easy readability. Data can be viewed through automatic scrolling or manual page-turning via intuitive touch buttons.

3. Flexible Communication: Equipped with both Infrared (IR) and RS485 communication interfaces, supporting Modbus/DLT645 protocols. The RS485 baud rate is configurable (9600/19200/38400/115200 bps).

4. Configurable Pulse Outputs: Provides two pulse outputs (SO1 and SO2) that can be configured to represent total active or reactive energy, allowing for integration with external monitoring systems.

Real-time Clock (RTC) & Multi-tariff Support: Includes a lithium battery for RTC functionality, enabling accurate timekeeping and multi-tariff (four tariffs: T1-T4) metering capabilities.

5. High Accuracy & Reliability: Meets Class B accuracy standards for active energy, ensuring precise metering. Designed to operate reliably in a wide temperature range of -40°C to 70°C, with an IP51 protection rating suitable for indoor environments.

Standard Compliance: Conforms to EN50470-1/3 standards, ensuring quality and performance.

Installation & Safety
