Carlo Gavazzi Monitoring Relay Voltage 3-Phase Din-Rail EUYC240

Carlo Gavazzi Monitoring Relay 3-Phase True RMS, Multi-Function, DIN-Rail, 2x SPDT, Supply: 240VAC.

True rms 3-phase monitoring relay for separate over and under voltage, asymmetry and phase failure control. The advantage of true rms measuring is that correct values are always obtained irrespective of the waveform of the measured voltage, i.e. the EUY measures the correct rms value of a normal sinusoidal power supply as well as of a distorted power supply. Frequency range 45 to 440 Hz. With relays measuring average value (EUB, EUC) correct values are only obtained for true sinusoidal power supplies. Often used in motor applications where it is important to detect the reliability of the electrical power.

General Characteristics

• True RMS measuring on own power supply.
• Frequency range 45-440 Hz.
• Monitoring relay and 3-phased measuring relay for over/under voltage control (closed circuit).
• Monitors phase asymmetry.
• Monitors phase loss/phase sequence.
• Measures if all 3 phase-phase voltages are within set limits.
• Upper and lower limits separately adjustable.
• Adjustable asymmetry.
• 2 separately adjustable time functions (0.1-30 s).
