Overview
The ADL200 is a standard rail-mounted single-phase energy meter designed for low-voltage residential and commercial buildings.
Featuring a 2-module ultra-slim profile, it can be flexibly installed in standard distribution boards.
It not only performs bi-directional active energy metering but also measures full electrical parameters such as voltage, current, and power in real-time. With support for RS485 communication and multiple standard protocols.
It is an ideal choice for sub-metering, equipment monitoring, and smart power distribution systems.

With its 2-module ultra-slim design and standard RS485 communication, it perfectly adapts to various new distribution boards and system integration projects. Whether for tenant billing in commercial buildings or sub-metering in factory workshops, the ADL200 provides accurate data support. For digital power distribution projects seeking standardization, high cost-performance, and easy integration, the ADL200 is a trustworthy choice.
FAQ
The ADL200 uses direct connection with a current specification of 10(80)A, suitable for single-phase circuits with maximum current not exceeding 80A, such as residential main inlets, shops, and small equipment. For loads exceeding 80A, it is recommended to use current transformers with other meter models.
Yes. The ADL200 measures both import active energy (consumption) and export active energy (e.g., from solar PV generation). The LCD displays an arrow indicating the current power direction, meeting the requirements of applications like distributed PV systems.
Yes. The ADL200 comes standard with an RS485 interface and supports MODBUS-RTU protocols. We provide a complete communication protocol register map, allowing users to integrate it into any SCADA, PLC, energy management system, or third-party cloud platform that supports these protocols.
Multi-tariff is an optional function (F). The meter has a built-in real-time clock. Users can set 14 time zones, 8 daily schedule tables, and 8 tariffs (e.g., peak, flat, off-peak) via buttons or communication. The meter automatically switches tariffs based on the set schedule and stores historical tariff energy data for the last 3 months, facilitating time-of-use billing and analysis.
The active power displayed should be positive, and the power factor should typically be between 0.8 and 0.95 (close to 1.0 for purely resistive loads). If the power is negative, it indicates the current input/output lines are reversed. In this case, you can use the DIR option in the settings menu (no for top-in bottom-out as positive, yes for bottom-in top-out as positive) to match the actual wiring without needing to rewire.
