- Bluetooth 5.1 module enabling 100-meter range wireless connectivity
Integrated ATS Control:
The AIG3320 replaces traditional standalone ATS controllers by providing built-in mains monitoring and transfer logic. The system continuously tracks grid health to trigger automatic generator start upon failure, then manages the switching logic between grid and generator power sources without manual intervention.
Cloud Integration & Data Intelligence:
The controller automatically synchronizes voltage and frequency data to AIGENSET’s dedicated global cloud service platform. The proprietary Black Box function records 18 seconds of operating data immediately preceding alarm-triggered shutdowns, enabling remote diagnostic feedback and traceable fault analysis. The system supports up to 106 historical fault records and 20 detailed abnormal shutdown logs.
Multi-Language Global Support:
Built-in interface support for English, Chinese, Spanish, and Russian languages ensures seamless operation across diverse international markets, eliminating communication barriers during installation, operation, and troubleshooting.
Security & Data Protection:
Multi-level permission passwords (Operator, Technician, Engineer) control access to critical parameters, while permanent FLASH data storage prevents information loss during power failures.
Industries Served:
The AIG3320 serves critical applications across multiple sectors including telecommunications base stations, healthcare facilities requiring uninterrupted power, manufacturing and industrial facilities, commercial standby power systems, construction and outdoor sites, field power stations, and generator fleet management for rental industry operations.
Case Studies & Quantifiable Results:
Rental Industry Equipment Management: Specialized generator rental companies managing decentralized equipment fleets face challenges with remote usage monitoring and preventing unauthorized use. After implementing the AIG3320 series with customized rental industry functions including multi-level passwords and parameter locking, operators achieved 100% remote monitoring of operating hours and data, reduced on-site maintenance visits through cloud diagnostics, and prevented equipment misuse via tiered password protection.
Construction & Field Sites in Harsh Environments: Outdoor construction projects and remote field stations operating in high-vibration and weather-exposed conditions deployed IP55-rated AIG3320 controllers with silicone panels and acrylic screen protection. The solution maintained stable operations in temperatures ranging from -25°C to +70°C and successfully resisted dust and water ingress through IP55 sealing, ensuring continuous power availability in challenging conditions.
Technical Certifications & Standards:
- IEC 688-1992 electrical isolation compliance
- IP55 protection grade (waterproof/dustproof with rubber ring)
- AC 1.5kV insulation strength certification
- Modbus protocol implementation for third-party system integration
- J1939 CANBUS electronic engine communication compatibility
Platform Compatibility: The AIG3320 supports single-phase two-wire, two-phase three-wire, three-phase three-wire, and three-phase four-wire AC systems at both 50Hz and 60Hz frequencies. Standard USB and RS485 interfaces utilizing the Modbus protocol enable seamless integration with existing infrastructure and third-party systems.
