Voltage relays - Monitored voltage range - 3 x 300 - 500 V AC
Wide range of relays for voltage and current monitoring in 1-phase and 3-phase networks. Simple, 1-module for basic functions, but also a sophisticated version for more accurate measurements in multiple ranges with galvanic separation of power supply from the measured circuit. The offer also includes a relay for monitoring the power factor in the range cos ϕ 0.1-0.99 and a relay for monitoring the mains frequency 50/60 Hz in the range 80-120%.
