Monitoring analyzer PFA64-1B1Z2-EMF FEMTO PRO D4 5A CLAMP

for electrical networksAC energy networkfor networks

Product overview
Harmonic & Power Quality Energy Analyzer for single and three-phase installations (up to 3 single-phase lines) with accuracy class 0.5S. Connects via external CTs (../5A or ../1A, not included). Measures THD and TDD on voltage and current, neutral current, maximum and minimum voltages, maximum current and power, and active energy per phase. Performs real-time single harmonic analysis up to the 31st order on three phase voltages and three line currents.

Features

• Integrated datalogger for recording four harmonic components.
• Total and per-phase energy counters.
• Recording of 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 configurable phase orientation.
• Four operating timers and eight configurable alarms with support for complex logic conditions.
• Graphical LCD display and calibration LED.
• Communication via Modbus-RTU over RS485.
• SIO Bus port for integration with Milli Pro I/O and Milli Pro Sensor expansion modules (additional inputs/outputs and environmental sensors).
• Firmware remotely upgradeable and expandable via PUK codes for future features.
• DIN-rail mounting, 4 modules; screw terminal connections for installation.
• Power supply: 230–240 VAC.
• Compliance: EN 50470-1 and EN 50470-3.
