Product name
PFA64-1H102-E00 FEMTO PRO D4 5A clamp RS485 230-240V

Description
Compact harmonic and power-quality energy analyzer for single- and three-phase systems (up to 3 single-phase lines) with accuracy class 0.5S. Designed for current transformer (CT) clamp connection (../5A or ../1A; CTs not included). Measures THD and TDD on voltage and current, neutral current, Vmax/Vmin, Imax, Pmax and active energy per phase. Performs real-time single-harmonic analysis up to the 31st order on three phase voltages and three line currents. Includes phase sequence detection and configuration, four operating timers and eight configurable alarms supporting complex logic conditions. Graphical LCD display and calibration LED. Communication via Modbus-RTU over RS485. Firmware remotely upgradeable and expandable via PUK codes. DIN-rail mounting (4 modules) with screw terminal installation. Power supply: 230–240 VAC. Complies with standards EN 50470-1 and EN 50470-3.
