OverviewHarmonic & Power Quality energy analyzer for single- and three-phase systems (up to 3 single-phase lines). Accuracy class 0.5S. Current input via CTs ../5A or ../1A (CTs not included).
Measurements- THD and TDD measurement on voltage and current
- Neutral current measurement
- Maximum and minimum voltage monitoring
- Maximum current and maximum power monitoring
- Active energy measurement per phase
- Single-harmonic analysis up to the 31st order on three phase voltages and three line currents in real time
Data Logging & EventsIntegrated datalogger records total and per-phase energy counters and logs voltage events (interruptions, sags, swells) for power quality analysis.
Functions & Alarms- Phase sequence detection and configuration
- Four configurable operating timers
- Eight configurable alarms with support for complex logic conditions
User Interface & CommunicationGraphical LCD display and calibration LED. Communication via Modbus-RTU over RS485. Firmware remotely upgradeable; expandable via PUK codes for future features.
Installation & PowerDIN-rail mounting (4 modules). Screw-terminal connections. Power supply: 230–240 VAC.
ComplianceCompliant with standards EN 50470-1 and EN 50470-3.
