Monitoring analyzer PFA64-EB1Z2-EMF FEMTO PRO D4 ECT CLAMP

for electrical networks3-phase electrical networksfor single-phase electrical networks

Product overview
Harmonic & Power Quality Energy Analyzer. Single/Three-Phase energy analyzer (up to 3 single-phase lines) with accuracy class 0.5S. Designed for use with external ECT current transformers (not included) — example: 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.

Functionality

• Single harmonic analysis up to the 31st order on the three phase voltages and three line currents in real time.
• Integrated datalogger for recording four harmonic components, total and per-phase energy counters, average, minimum, and maximum values of voltage, current, power, and frequency.
• Records and stores voltage events (interruptions, sags, and swells) for power quality analysis.
• Phase sequence detection and configuration.
• Four operating timers and eight configurable alarms, including support for complex logic conditions.
• Graphical LCD display and calibration LED for local monitoring and status indication.
• Communication via Modbus-RTU RS485.
• SIO Bus port for integration of Milli Pro I/O and Milli Pro Sensor expansion modules (additional I/Os and environmental sensors).
• Firmware remotely upgradeable and expandable through PUK codes for future upgrades even after installation.

Mechanical and 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.
