Basler Electric SGC-250N Synchronous Generator Controller

Overview

The SGC-250N Synchronous Generator Controller is a prepackaged solution

for applications that require single or dual DECS-250N Digital Excitation Control

Systems. With the DECS-250N’s enhanced capabilities and negative forcing,

precise generator voltage control can be obtained. An optional integrated BE1-11g

Generator Protection System provides generator current differential protection,

monitoring, and metering with multiple generator protection schemes.

• CAN bus communication

• Modbus® RS-485 RTU

• Ethernet 100Base-T (Modbus TCP)

• Reactive load sharing over communication

• Field flashing provisions

• Provisions for sync check

• Optional automatic synchronizer

• Optional integrated power system stabilizer (PSS)

• Optional BE1-11g Generator Protection System available on

pan chassis/mounting plate

Benefits

• Negative forcing provides exceptional responses to system

transients and load disturbances.

• The DECS-250N and optional BE1-11g used on the SGC-250N

are programmed using BESTlogic™Plus within BESTCOMSPlus

software. With its intuitive interface, BESTlogicPlus provides

the flexibility to create custom logic schemes to meet specific

requirements.

• An automatic tuning feature is integrated into the DECS-250N

to reduce commissioning time and provide excellent system

performance.

• Real time monitoring and event recording capture occurrences

within the system for live data analysis.

• Prewired for easy installation into new or existing enclosures.

• Dual control power provides redundancy to prevent undesired

shutdown.

• Current transformer (CT) shorting provision for added safety.

• The SGC-250N is designed, built, and tested to optimize

performance and reliability.
