MFR 300 produktspecifikation

MFR-300 Multifunction Relay / Measuring Transducer with CANopen / Modbus Communication

The MFR 300 is a measuring transducer for monitoring single- and three-phase power systems. The MFR 300 has both voltage and current inputs for measuring an electrical power source. A digital processor makes it possible to accurately to measure true RMS values, regardless of harmonics, transients or disturbing pulses. The primary measured and calculated values are transmitted via CANopen / Modbus protocol to a supervisory control system.
The MFR 300 performs monitoring functions for mains decoupling, including four freely configurable time-dependent undervoltage monitoring functions for FRT (fault ride-through).
The primary measured values of voltage and current are used to calculate the real, reactive, and apparent power and the power factor (cosphi) values.
