Woodward MFR-300 Multifunction Relay

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.

Multifunction Relay and Measuring Transducer. Precision Measurement.

Reliable Monitoring. The MFR-300 is a compact and efficient device that

combines measurement and monitoring functions to support modern

electrical power system. It provides precise monitoring and dependable

protection, making it a valuable tool for managing power systems effectively.

Features and Benefits

• Seamless Communication:

The MFR-300 integrates with supervisory control systems via CANopen or

Modbus protocols, enabling smooth data transmission and real-time monitoring.

• Power Calculations:

The device calculates essential parameters such as real power, reactive power,

apparent power, and power factor (cosφ), providing a complete picture of

your system’s performance.

• PLC Connectivity:

Connect a programmable logic controller (PLC) via CAN bus for enhanced

automation and control capabilities.

Accessories

• Toolkit:

Configuration via Woodward’s standard Software Toolkit.

• USB configuration interface:

USB port configuration interface. The PC/laptop side is seperated from the

Woodward unit side through galvanic isolation.
