German Engineering

The RSAPC was built to bring Server grade performance, reliability and security to the harshest operating environments and meet the stringent certification requirements for substation automation. Assembled and tested in Germany, we ensure quality and performance for each unit.

To enable reliable calculations in demanding industrial and substation applications, the RSAPC offers a highly reliable ECC storage, a wide temperature range, solid-state drives and an effective heat management system with heat pipes for heat dissipation and a heating system that ensures a reliable start at temperatures below zero.

With its high-performance Intel Xeon quadcore/octathread processor, vPro Remote management support and integrated TPM 2.0, the RSAPC offers advanced security and management features on top of silent operation without moving parts.


Design quality, dependable components and a maintenance free cooling system strive to eliminate critical components, to keep your critical application running.
Eliminating moving parts like fans and conventional spinning hard disc drives removes the most common sources of failure from the Computer system. With its unique thermal management system, the Welotec RSAPC allows to operate in environments with up to 75°C (167°F), due to heat pipes that connect all critical components to generously sized heatsinks, and the electrical heating systems enables reliable boot up behaviour at -40°C (-40°F).

High Availability

Array of solid-state drives to drive availability up to the standards for critical applications. Problems with dust, worn down bearings and failing fans are eliminated by removing all moving parts from the system design.

ECC protected system memory can correct any single bit error in the RSAPCs main memory and prevents flipping bits from crashing core applications or introducing logic errors while controlling critical infrastructure.

For maximum availability, redundant AC and DC power supplies can be combined as required.
•AC power supplies with 90 to 240 V AC
•DC power supplies with 17 to 160 V DC


The RSAPC is easy to maintain in the fi eld, the redundant hot-swap power supply modules and the 2.5” solid state drives can be replaced without shutting the system down. RAM upgrades can be done without opening the main chassis via a small service hatch.



Remote management is available via Intel´s Active Management Technology (iAMT) that allows maintenance, software updates and system diagnostic from afar, even when the RSAPC is powered down. With the integrated KVM-over-IP function all system functions are available, as if the operator is present at the local device.


Fully featured system for maximum utility

The Welotec RSAPC comes with an extended I/O feature set, that includes most commonly used I/O ports in the base system, and hence eliminating the need to use PCIe extension ports for those expansions in most applications. With build in iAMT remote management functions and an on board TPM 2.0 module the RSAPC provides both, modern administration and security tools.

Virtualisation and Cyber Security

The Welotec RSAPC is designed to implement modern IT structures and realize the most benefit from virtualisation to reduce hardware cost, increase availability and security. With its 64GB of main memory the RSAPC can run several virtual machines while assigning each of them the resources of a standalone system.

Isolating applications
Virtualisation allows for each application to run in its own virtual machine (VM) and thereby isolate tasks from each other. Rebooting a VM after an update does only affect the function being updated as all other VMs can remain online and running.

Sustained use of software investments
Industrial applications often entail using custom made or older software, whose operating system has become obsolete and is not supported by new hardware. Virtualisation offers a way out by simulating legacy hardware. The RSAPC is designed with this use case in mind. To allow legacy software that requires a USB dongle it come with an internal USB dongle slot.

Cyber security
Current changes in the legal environment, like the European Network and Information Security directive and common-sense demand to protect critical infrastructure against malicious and accidental infections as well as against deliberate hacking attempts. The RSAPC with its sever grade resources allows to use an industrial Intrusion Detection System in a virtual machine without increasing hardware outlay.

Cost reduction
In critical applications, customers expect redundancy and the ability to absorb the failure of a single device. Virtualization allows multiple applications to be redundantly designed and isolated from each other without requiring more than two RSAPCs.
Due to its high computing power, which supports up to 64GB RAM, one RSAPC can replace up to four previous generation systems in terms of performance and memory.
