ACREL Rail-Mounted DC Multifunction Power Meter with RS485 Modbus-RTU
Rail-Mounted DC Multifunction Power Meter with RS485 Modbus-RTU is a rail-mounted DC multifunction power meter for monitoring electrical parameters in DC power distribution and energy systems. It is suitable for applications such as DC panels, solar photovoltaic systems, telecommunications base stations, energy storage systems and electric vehicle charging equipment. Key features include voltage, current, power and energy measurement, RS485 Modbus-RTU communication, relay alarm output, digital input, event recording and programmable settings.
The Rail-Mounted DC Multifunction Power Meter with RS485 Modbus-RTU is a DC multifunction power meter designed for real-time measurement and monitoring of electrical parameters in DC power systems. As part of DC multifunction meter range, it provides an effective way to collect electrical operating data and make that information available locally and through digital communication systems.
The meter can monitor important DC electrical parameters including voltage, current, power and energy. It also supports additional monitoring and control functions, including relay alarm output and digital input, making it useful for applications where electrical conditions need to be continuously supervised.
How Does It Work?
The Rail-Mounted DC Multifunction Power Meter with RS485 Modbus-RTU measures electrical signals from the connected DC system and calculates relevant power and energy parameters. The information can be viewed through the meter's local interface and transmitted to a supervisory or energy management system through its RS485 communication interface using Modbus-RTU protocol.
Users can configure parameters such as measurement ratios, alarm settings and communication settings through the meter's panel keys. The device also supports functions such as switch event recording, programming and event-setting records, instantaneous and scheduled data freezing, and recording of maximum and minimum voltage, current and power values.
