APPLICATIONS

Based on micro-controller technology,Woodward's MFR 2 Multi FunctionRelay incorporates functions andfeatures for multiple applications (e.g.gensets, hydropower, etc.) in isolatedor parallel utility operation. The MFR 2is designed for generators andswitchgear equipment that requireindependent protection.

The ability for the MFR 2 to quicklydecouple from the mains whenworking in parallel with the mainsgives complete generator protectionfor frequency, voltage, and real and re-active power control allowing load/varsharing between as many as eightunits.

DESCRIPTIONThe Series of MFR 2 Multi FunctionRelays consists of the modelMFR 2S/PSVA.

Features Battery voltage monitoring kWh/oper.hours/start/maintenance

counter 4 configurable discrete alarm inputs 4 configurable relays Two-line LC display Synchroscope Multi level password protection Configuration directly or via PC CAN bus communication
