Description
Product overview
Harmonic & Energy Analyzer for power quality (up to 3 single-phase lines) with overall accuracy Class 1 (Femto Pro F + flexible CTs).
Connection via FCTS series flexible split-core CTs (not included), configurable full scale up to 4000 A.
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.
Integrated datalogger recording four harmonic components, total and per-phase energy counters, and average/minimum/maximum values of voltage, current, power and frequency.
Records and stores voltage events (interruptions, sags and swells) for power quality analysis.
Includes phase sequence detection and configuration.
Features four operating timers and eight configurable alarms with support for complex logic conditions.
Equipped with a graphical LCD display and a calibration LED.
Communication via Modbus-RTU over RS485 and SIO Bus for integration of Milli Pro I/O and Milli Pro Sensor expansion modules.
Firmware remotely upgradeable and expandable via PUK codes.
DIN-rail mounting, occupies 4 modules; installation via RJ45 connectors and removable terminal blocks.
Power supply: 230–240 VAC. Standards: EN 50470-1, EN 50470-3.
