ABB A44-552-100 kWh METER 6A, 3 PHASE CT CONNECT WITH CONFIGURABLE I/O & MODBUS RTU, PLATINUM FUNCTIONALITY

The A44-552 energy meter is a three-phase device that operates at 230VAC and has a current rating of 6A. It features configurable I/O and Modbus RTU communication for easy integration into existing systems. This energy meter offers high accuracy, with an active energy class of 0.5% and a reactive energy class of 2%. It can measure voltage in the range of 100-500V (L-L) and 57.7-288V (N-L). With an IP20 protection degree, this meter is suitable for indoor use. It also has a backlit pixel-oriented LCD display for clear visibility in any lighting conditions. The A44-552 energy meter belongs to the Platinum sub-group, which provides various functionalities such as measuring active, reactive, and apparent energy, as well as import/export of energy. It also features resettable energy registers, harmonics measurement, and configurable I/O (except for the 690V meter which has fixed I/O). In terms of clock functions, this meter offers advanced options like load profiles, as well as basic functions including tariff control, previous values tracking, max/min demand calculation, and event logging. Depending on the requirements, this meter can be configured to operate in either Class 0.5 or Class 1 mode. It supports multiple tariffs and has fixed I/O options available. Additionally, it offers pulse output/alarm functionality. The A44-552 energy meter is designed to be mounted on a DIN rail and occupies seven modules of space. Overall, this versatile energy meter provides accurate measurements and a range of useful features for monitoring electrical consumption in three-phase systems.
