Reactive kVAR Control

• VAR (PF) sharing on isolated busses using percentage based reactive load sharing

• Voltage bias signal to AVR configurable for discrete raise/lower,4–20 mA, ±1. ±3. or ±9 Vdc

• Power factor or VAR control when base loaded

• Externally adjustable VAR or PF setpoint levels

• Manual voltage control capability

• Configurable load/unload ramp rates

Synchronizing

• Phase match or slip frequency synchronization with voltage matching

• Full three-phase sensing on both busses

• Manual synchronization capability

• Adjustable phase window, voltage window, reclose attempts, reclose timing

• Safe dead bus closing logic internal to the control

• Synch check (25)

• Breakers or contactors

Automatic Unit Sequencing

• Automatically starts and stops gen-sets based on plant bus demand

• Automatic generator set loading and unloading for bumpless transfer

• Configurable plant bus demand startstop levels and timers

• Configurable generator priority sequencing

Communications

• Modbus® RTU or DDE communications via RS232 (1 each) and RS-232/422/485 (2 each) serial ports

• Echelon® TP/XF-1250 network

• CAN 2.0b Network (OEM option only)
