The A43-513 energy meter is a direct connect meter designed for three-phase systems with a maximum current of 80A and voltage of 230 VAC. It features configurable I/O and M-Bus TP communication for easy integration into existing systems. This energy meter offers high accuracy, with active energy measured at class 1% and reactive energy at class 2%. The measurement range is from 100 V to 500 V for line-to-line voltage and from 57.7 V to 288 V for neutral-to-line voltage. With an IP20 protection degree, this meter provides reliable performance in various environments. It also features a backlit pixel-oriented LCD display for clear visibility. The A43-513 energy meter belongs to the sub-group Platinum functionality, offering a wide range of features. These include measuring active, reactive, and apparent energy, as well as import/export of energy. The meter also has resettable energy registers and can measure harmonics. For ease of use, the configurable I/O allows customization of inputs and outputs (except for the 690 V meter which has fixed I/O). The advanced clock functions enable load profiles, while basic clock functions include tariff control, previous values, max/min demand, and event log. This energy meter can be configured as either Class 0.5 or Class 1 accuracy. It supports tariffs and has fixed I/O options available. Additionally, it offers pulse output/alarm functionality. The A43-513 energy meter is seven modules wide and can be easily mounted on a DIN rail. Overall, this versatile energy meter provides accurate measurements and a wide range of functionalities for efficient monitoring and management of electrical systems.
