In process industries, power reliability is a core requirement for safe and efficient operations. Production plants, refineries, offshore platforms, and chemical facilities operate in environments where power interruptions can lead to safety risks, production losses, and regulatory issues.
For these reasons, SIL 3 power supply systems play a key role in supporting mission-critical applications.
GM International designs and manufactures SIL 3 certified power supply systems developed to ensure continuous and reliable power in hazardous and demanding industrial environments. Operating at 24 Vdc and suitable for installation in Zone 2 / Div. 2 areas, these solutions meet the requirements of industries where safety and availability cannot be compromised.
Why SIL 3 Power Supply Systems Matter in Hazardous Areas
SIL 3 power supply systems are designed to ensure continuous and reliable power for safety-critical applications in hazardous industrial environments. They provide a very high level of risk reduction, supporting functional safety requirements in oil & gas and chemical plants where power failure can compromise people, processes, and assets.
Functional Safety and Compliance
SIL 3 certification supports compliance with international functional safety standards and ensures dependable performance in safety-related applications commonly used in oil & gas and chemical plants.
Reliability for Continuous Processes
Designed for continuous operation, SIL 3 power supply systems help maintain stable performance over time, even in harsh industrial conditions and demanding operating environments.
Modular and Redundant Power Supply Architecture
A modular and redundant power supply architecture ensures uninterrupted operation by maintaining power availability even if one module fails. Configurations such as N+N, N+1, and N+2 are widely used in mission-critical systems to maximize reliability and plant uptime.
Integrated Active OR-ing Technology
Active OR-ing technology allows multiple power supply modules to operate in parallel without external diodes, improving efficiency and reducing power losses. This results in simpler system design and higher overall reliability.
Automatic Load Sharing
Automatic load sharing distributes electrical load evenly across power modules, preventing overload and extending component lifetime. This feature improves long-term reliability and reduces maintenance needs in continuous-process industries.
Flexible Installation of Power Supply Systems for Process Industries
To meet different plant requirements, GM International SIL 3 power supply systems are available in several formats:
- DIN rail power supplies for control cabinets
- Wall-mounted solutions for field installations
- Rack-based systems for centralized power distribution
Features such as hot-swappable modules and advanced diagnostics enable fast maintenance while minimizing downtime and supporting continuous plant operation.
Benefits for Plant Operators and System Integrators
- High availability for mission-critical applications
- Reliable power supply for hazardous areas
- Reduced downtime and maintenance costs
- Long-term operational efficiency
Conclusion: Reliable Power as a Foundation for Industrial Safety
In process industries such as oil & gas, chemical, and petrochemical, and more generally in applications where power failure can lead to data loss, production downtime, or safety risks, reliable power is not just a technical requirement, it is a foundation for safe and efficient operations. By choosing SIL 3 power supply systems from GM International, plant operators and system integrators can rely on proven solutions designed to support safety, continuity, and long-term performance.
