Monitoring analyzer PRA64-EB1Z2-EMF FEMTO PRO D4 ECT PLUG

for electrical networksindustrialpower

Product overview
Harmonic & Power Quality energy analyzer for single- and three-phase systems (up to 3 single-phase lines). Accuracy class 0.5S; designed for use with external ECT current transformers (not included). Real-time single-harmonic analysis up to the 31st order on three phase voltages and three line currents. Integrated datalogger, event recorder for voltage interruptions/sags/swells, phase sequence detection, four timers and eight configurable alarms. Graphical LCD and calibration LED. Communication via Modbus-RTU (RS485) and SIO Bus for Milli Pro expansions. DIN-rail mount, 4 modules. Power supply 230–240 VAC.
