Monitoring analyzer PFA64-EB102-EM0 FEMTO PRO D4 ECT CLAMP

for electrical networksindustrialpower quality

Product overview
Harmonic & Power Quality Energy Analyzer suitable for single- and three-phase installations (up to 3 single-phase lines). Accuracy class 0.5S. Uses external ECT current transformers (not included), e.g. 100A model 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. Performs single harmonic analysis up to the 31st order on the three phase voltages and three line currents in real time.

Data logging and events
Integrated datalogger records total and per-phase energy counters and logs voltage events (interruptions, sags and swells) to support power quality analysis and troubleshooting.

Functionality & features
Phase sequence detection and configuration. Four operating timers and eight configurable alarms with support for complex logic conditions. Graphical LCD display and calibration LED for on-site verification. Communication via Modbus-RTU over RS485. Firmware remotely upgradeable and expandable through PUK codes for future functions.

Installation & compliance
DIN-rail mounting, 4 modules. Wiring via screw terminals. Power supply: 230–240 VAC. Compliant with standards EN 50470-1 and EN 50470-3.
