Description

Product overview
  • Single/three-phase energy analyzer (up to 3 single-phase lines).
  • Accuracy class 0.5S.
  • Designed for use with external ECT current transformers (not included), e.g. 100A model code PFAE000-09.
  • Measures THD and TDD on voltage and current, neutral current, maximum and minimum voltage, maximum current and power, and active energy per phase.
  • Phase sequence detection and configurable phase settings.
  • Four operating timers and eight configurable alarms with support for complex logic conditions.
  • Calibration LED for energy, status LED and RS485 communication LED.
  • Communication: Modbus-RTU over RS485.
  • Firmware remotely upgradeable and expandable via PUK codes for future features after installation.
  • DIN-rail mounting, 4 modules; installation via screw terminals.
  • Power supply: 230–240 VAC.
  • Complies with standards EN 50470-1 and EN 50470-3.
