The A44-553 energy meter is a three-phase device that operates at 500VAC and has a current transformer (CT) connection of 5A. It features pulse output and RS485 Modbus TCP communication for easy integration into existing systems. With an accuracy class of 1, this energy meter provides precise measurements. It can measure voltage ranges from N-L 57.7-288V and L-L 100-500V. The meter has a protection degree of IP20, ensuring its durability in various environments. The large backlit LCD display allows for easy reading of the measured values. The meter belongs to the sub-group Platinum functionality, offering a wide range of features such as active, reactive, and apparent energy measurement, import/export of energy, resettable energy registers, harmonics analysis, and configurable I/O (except for the 690V meter which has fixed I/O). Additionally, the meter offers advanced clock functions like load profiles and basic clock functions including tariff control, previous values tracking, maximum/minimum demand calculation, and event logging. It can be configured as either Class 0.5 or Class 1 according to specific requirements. The meter supports tariffs and has fixed I/O options available. It also provides a pulse output/alarm feature. The A44-553 energy meter is designed to be mounted on a DIN rail and occupies seven modules in width.
