SPM-D21 Series

Synchronizing

• Separately for GCB and MCB
• Phase match or slip frequency synchronization with voltage matching
• Two-phase sensing of generator, bus, and mains
• Selectable operating modes like SPM-A (Run, Check, Permissive, and OFF)
• Synchro-check possible
• Synchronization time monitoring

Mains parallel operation

• Real power control
• True RMS power calculation
• Generator real power setpoint by parameter (2 values) or via 0/4 to 20 mA
• Soft shutdown
• Power factor control
• Power factor setpoint by parameter

Isolated operation

• Frequency control
• Voltage control

Dead bus operation

• Closing of GCB or MCB on demand
