Description
The ComAp InteliGen GSC-C is a high-end paralleling controller from the legacy NTC-standard family, specifically optimized for Grid Support (GSC). While the standard InteliGen NTC focuses on gen-set management, the GSC-C (Grid Support Controller – Communication) is designed for critical infrastructure like data centers and hospitals that must satisfy strict international grid code requirements.
Key Features of the InteliGen GSC-C
-
World Grid Code Compliance: Native support for international standards like G99 (UK), VDE-AR-N 4110/4105 (Germany), and IEEE 1547 (USA).
-
Controller Redundancy: Essential for mission-critical sites, allowing a second controller to act as a “hot-standby” to ensure power is never compromised.
-
Start-Up Synchronization: Unique logic that allows a large bank of generators to synchronize and close onto a dead bus simultaneously, significantly reducing blackout time.
-
Integrated Communication: Features built-in Ethernet, USB, and multiple RS485/RS232 ports for seamless BMS and SCADA integration.
-
Dynamic Spinning Reserve: Specifically tracks renewable output (PV/Wind) and keeps just enough gen-set capacity online to cover potential drops in weather-dependent energy.
Comparison Table: InteliGen GSC-C vs. Newer Generations
The InteliGen GSC-C is a robust legacy controller. Its modern successor is the InteliGen 1000, which offers a higher gen-set count and advanced “Cybersecurity by Design.”
| Feature | InteliGen GSC-C | InteliGen 4 200 | InteliGen 500 G2 | InteliGen 1000 |
| Primary Use | Grid Support / Critical | Common Paralleling | Advanced Paralleling | Flagship / Grid Ready |
| Grid Code Support | Certified / Advanced | Basic | Standard | Certified / Advanced |
| Max Gen-sets | 32 | 32 | 32 | 64 |
| Ethernet | Built-in | Optional (Plug-in) | Built-in | Dual Built-in |
| Form Factor | Integrated Hardware | Integrated Display | Integrated 5″ Color | BaseBox (No Display) |
| Cybersecurity | Standard (Password) | High (Encrypted) | High (Encrypted) | Highest Level |
| Redundancy | Controller Redundancy | Limited | Controller Redundancy | Hot Swap Redundancy |
Technical Notes:
-
Hardware vs. Software: The “GSC-C” is essentially a high-performance hardware platform (order code
IG2GSCCXBAB) that runs specialized firmware. It can be converted into a mains controller (InteliMains GSC) via a simple firmware upload. -
Display Flexibility: While it has a physical interface, it is fully compatible with the InteliVision family (5, 8, 12Touch, and 18Touch) for users who want a high-resolution color overview of their switchgear.
-
Legacy Advantage: For technicians familiar with the older GenConfig software, the GSC-C is easier to commission than the newer InteliGen 1000, which uses the InteliConfig suite.
