The DIN Rail Single Phase Smart Energy Meter with RS485 is a advanced electrical device designed for accurate measurement and monitoring of single-phase AC electrical energy consumption. It features a high-precision sensor that measures voltage, current, power factor, and energy consumption in real-time. The meter is equipped with an RS485 communication interface, allowing for remote data collection and integration with smart grid systems, building automation systems, and energy management platforms.
Designed for DIN rail mounting, this smart energy meter is easy to install in residential, commercial, and industrial settings. It has a compact design that fits seamlessly into standard electrical panels, saving space while providing comprehensive energy measurement capabilities. The meter also features a clear LCD display that shows real-time energy consumption data, making it easy for users to monitor their energy usage at a glance.
High-Precision Measurement: Accurately measures voltage, current, active power, reactive power, power factor, and energy consumption with a high degree of precision.
RS485 Communication: Enables remote data transmission and integration with various monitoring systems, allowing for real-time energy management and analysis.
DIN Rail Mounting: Simple and convenient installation on standard DIN rails, suitable for both new installations and retrofitting existing systems.
Compact Design: Space-saving design that fits into small electrical panels, ideal for residential and commercial applications where space is limited.
LCD Display: Provides clear and detailed information about energy consumption, including instantaneous values and cumulative totals.
Multiple Functions: Supports features such as load profile recording, event logging, and tamper detection, enhancing security and energy management capabilities.
This smart energy meter is suitable for a wide range of applications, including residential homes, commercial buildings, small industrial facilities, and renewable energy systems. In residential settings, it helps homeowners monitor and manage their energy usage, leading to potential cost savings. In commercial and industrial applications, it enables businesses to track energy consumption by department or equipment, identify inefficiencies, and implement energy-saving strategies. The RS485 communication feature makes it an ideal choice for smart grid projects and building automation systems, where centralized energy management is required. It can also be used in solar and wind energy systems to monitor the energy generated and consumed by the system.
Q: What is the communication protocol used with the RS485 interface?
A: The meter typically uses the Modbus RTU protocol, which is widely supported by most energy management systems.
Q: Can it be used with both single-phase and three-phase systems?
A: No, this meter is designed specifically for single-phase systems. For three-phase applications, a three-phase smart energy meter should be used.
Q: How is the meter calibrated?
A: The meter is factory-calibrated to ensure accuracy. However, it can be recalibrated if necessary using appropriate calibration equipment.
Q: Does it require a separate power supply?
A: It can be powered by the single-phase electrical system it is monitoring, so no separate power supply is usually required.
Q: What is the maximum current rating of the meter?
A: The maximum current rating varies depending on the model, but typical ratings range from 5A to 100A. Please refer to the product specifications for the exact rating of the model you are using.
