This device also performs the function of a Web Server and datalogger, allowing users to easily access key parameters and access data efficiently.
The user also has the option of transferring data via FTP. Some of its advanced features include:

  • Universal Input: Each device can be configured to accept single-phase, three-phase, TA, and TA with mV or Rogowski sensor inputs as required.
  • MQTT and HTTP POST Supported: Integrating advanced protocols, it offers instant access to real-time energy data wherever you are.
  • 8MB Data Memory: Equipped with enhanced memory for data/event storage, harmonics up to 55°A and THD, ideal for system analysis and optimization.
  • Maximum Flexibility: Also in the choice of power supply and Ethernet ports through which R203 offers ModBUS TCP-IP / ModBUS RTU gateway functions
  • Digital I/O Channels: Features 2 digital outputs and 2 independent inputs with 32-bit meters for active, reactive, and apparent energy metering.

With our R203 power meter, you get a reliable and versatile tool for monitoring and managing your power grid.
