Modbus Meter for Charging Stations – Precise Measurement and Energy Consumption Optimization

This 3-phase Modbus meter, with a rated current of 80A, is specifically designed for use in electric vehicle charging stations (EVCS). It enables accurate measurement of energy consumption, which is crucial for dynamic load modulation and optimization of excess energy utilization from photovoltaic installations. Compatible with the DLM (Demand Load Management) system and equipped with an XVA246 card, it is a reliable solution for both installers and end users.

Design and Application

The XVA630 meter is mounted on a DIN rail, ensuring quick and easy installation in a distribution board. Its compact dimensions (92 mm high, 72 mm wide and 60 mm deep) allow for installation even in limited spaces. The device is intended for direct measurement of electrical energy in three-phase circuits (3P+N), offering precise data on power consumption. Thanks to the optical pulse output, remote data reading and integration with monitoring and energy management systems are possible.
