Energy meters are essential components in any electrical system, providing crucial data on energy consumption. While AC energy meters are widely used for measuring alternating current, DC meters are specifically designed to measure direct current. The EM Series DC energy meters, equipped with RS485 communication capabilities, offer a robust and efficient solution for monitoring and managing DC power systems. it is compliant with Eichrecht standards in Germany, MID (Directive 2014/32/EU), French regulations and meet North American regulations.
1. Brief introduction
Energy meters are essential components in any electrical system, providing crucial data on energy consumption. While AC energy meters are widely used for measuring alternating current, DC meters are specifically designed to measure direct current. The EM Series DC energy meters, equipped with RS485 communication capabilities, offer a robust and efficient solution for monitoring and managing DC power systems.
2. Function Description
Precision Measurement: These meters employ Shunt Sampling for DC measurement, ensuring high accuracy (Class 1) across a wide range of current and voltage levels (10-240A, 40-400VDC).
Comprehensive Data: The meters measure vital parameters such as current (I), voltage (V), and cumulative energy consumption (kWh).
Communication: RS485 communication with the DTL645 protocol enables seamless integration with various supervisory control and data acquisition (SCADA) systems and other smart grid technologies.
Enhanced Safety: Built-in over-current and over-voltage alarm functions provide crucial protection for the system and equipment.
User-Friendly Interface: An LCD display with backlight and four tariffs with 8 time slots facilitates easy monitoring and data analysis.
Versatility: The compact and robust design makes these meters suitable for a wide range of applications, including:
Electric Vehicle Charging Infrastructure: Precisely measure energy consumption at EV charging stations and within charging networks.
