Introduction

The RE-211 Energy Analyzer (hereinafter also referred to as the "Analyzer" or the "Product") is a compact, high-precision instrument designed for continuous monitoring of electrical parameters in single-phase applications.

The device measures line voltage and current and calculates active, reactive, and apparent energy, as well as instantaneous RMS voltage and current values.

Thanks to its DIN rail mounting and direct power supply from the measurement line, it provides a versatile and reliable solution for real-time measurement applications, long-term data logging, and detection of power quality events such as voltage sags and swells.

Main functional features:

  • Active, reactive, and apparent power measurement
  • Active, reactive, and apparent energy measurement
  • IRMS and VRMS measurement
  • Power factor calculation
  • Sag and peak detection on voltage and current channels
  • Frequency: 50–60 Hz
  • 0.96" monochrome OLED display
  • NTP time synchronization
  • 2.4 GHz Wi-Fi / Bluetooth® LE connectivity
  • Modbus TCP/IP and MQTT/MQTTs communication
  • Internal storage of measurement data and events
