APPLICATIONS

Based on micro-controller technology,Woodward's MFR 2 Multi Function Relay

incorporates functions and features for multipleapplications (e.g. gensets, hydropower, etc.) inisolated or parallel utility operation. The MFR 2is designed for generators and switchgearequipment that require independent protection.

The ability for the MFR 2 to quickly decouplefrom the mains when working in parallel withthe mains gives complete generator protectionfor frequency, voltage, and real and re-activepower control allowing load/var sharingbetween as many as eight units.

DESCRIPTION (MFR 2/PSV)The Series of MFR 2 Multi Function Relaysconsists of three models. The MFR 2/PSV isthe base model. The MFR 2/PSVA hasadditional features, and the MFR 2/PSVT is forspecial applications.

Features (all versions) 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
