The Rugged Substation Automation Devices by Welotec

The Devices are facing special challenges in the substation environment. 
The Rugged Substation Automation PC Mk2 (RSAPC Mk2), the Rugged Substation Automation Gigabit Switch (RSAGS) and the Rugged Substation Automation Ethernet Switch (RSAES) by Welotec are designed precisely for this. With an operating temperature range of -40 to +70 °C, the devices are designed for extreme conditions and deliver constant and robust performance, allowing for the running of additional applications that enhance efficiency.

A groundbreaking product that ensures reliable 
performance in demanding environments.


IEC 61850-3

The Rugged Substation Automation Devices by Welotec consistently meet the requirements of the IEC 61850-3 standard. They fulfill the EMI/RFI resistance requirements specified in the standard, thereby ensuring interference-free operation in electromagnetically demanding environments. The specifications for network and data interfaces are also met, enabling efficient and reliable communication. This makes the Welotec Rugged Substation Automation Devices ideal for demanding use in substations.



Virtualize Your Substation Applications

The virtualization of applications in substations is a significant step forward in energy infrastructure. IEC61850-3 compliant solutions make it possible to virtualize a wide range of applications in substations.


The integration of SCADA systems and human-machine interfaces (HMI) offers improved monitoring and control capabilities in substations and represents a significant advance in the energy infrastructure. IEC61850-3 compliant solutions enable virtualization of applications such as phase measurement (vPMU) and remote terminal units (RTU). Virtualization of firewall (vFW) functions contributes to safety and revolutionizes the way we operate and maintain substations. By applying artificial intelligence (AI) and machine learning (ML), processes can be optimized and anomalies detected at an early stage.



The RSAPC Mk2 Rugged Substation Automation Server offers outstanding performance and a space-saving design for critical infrastructures. Its innovative heat dissipation system optimizes space utilization in server racks.
