Overview
ADL200(MID) is a single-phase DIN rail energy meter designed for active energy measurement in low-voltage residential and commercial applications.
It features MID certification (Class B accuracy) , meeting the stringent requirements of the IEC62053-21 and IEC62053-22 standards for legal metrology in Europe.
The meter measures bi-directional active energy and full electrical parameters (voltage, current, power, power factor, frequency), with RS485 Modbus-RTU communication.
Its compact 2-module design enables easy installation in standard distribution boards, making it ideal for submetering applications requiring MID-compliant billing-grade metering.

FAQ
ADL200(MID) is certified to Class B accuracy according to IEC62053-21/22 standards and carries MID certification, making it suitable for legal metrology and billing applications in Europe. The standard ADL200 meets GB/T standards with Class 1 accuracy for general monitoring applications.
Yes, multi-tariff is an optional function (F). When selected, it supports 4 time zones, 4 time interval lists, 14 daily time intervals, and 4 tariff rates (spike, peak, flat, valley), with 3 months historical data freeze for TOU billing applications.
ADL200(MID) features an RS485 interface with MODBUS-RTU protocol. The complete Modbus address list is provided in the manual for easy integration into any SCADA, PLC, or energy management system.
The active power displayed should be positive, and power factor typically between 0.8-0.95. If power is negative, current lines are reversed. The DIR parameter in settings allows matching the actual wiring without rewiring (no for top-in bottom-out as positive, yes for bottom-in top-out as positive).
The pulse constant is 1000 imp/kWh, meaning the meter outputs 1000 pulses for every 1 kWh of energy consumed. Each pulse has a width of 80±20ms. This allows for external verification or integration with pulse counting systems.
Summary
ADL200(MID) DIN rail energy meter is a MID-certified, Class B accuracy metering solution for professional billing and submetering applications. Its compact 2-module design, standard RS485 Modbus communication, and optional multi-tariff functionality make it a versatile choice for residential, commercial, and industrial energy monitoring. For projects requiring legal metrology compliance in Europe and beyond, ADL200(MID) delivers reliable performance with full certification.
