APPLICATIONS

Based on micro-controller technology, Woodward's MFR 2 Multi Function Relay incorporates functions and features for multiple applications (e.g. gensets, hydropower, etc.) in isolated or parallel utility operation. The MFR 2 is designed for generators and switchgear equipment that require independent protection. The ability for the MFR 2 to quickly decouple from the mains when working in parallel with the mains gives complete generator protection for frequency, voltage, and real and re-active power control allowing load/var sharing between as many as eight units.

DESCRIPTION

The Series of MFR 2 Multi Function Relays consists of the model MFR 2S/PSVA.
