UBR-03 - BACnet Router

With the new UBR-03, MBS is expanding its portfolio to include a high-performance BACnet router for BACnet/SC (Secure Connect). The router was specifically designed for large buildings, campus solutions, industrial facilities, and critical infrastructure, where secure and reliable communication plays a central role.

The UBR-03 combines the proven technology of the MBS router family with significantly greater processing power and expanded memory. It thus provides the ideal conditions for use in large-scale BACnet/SC networks.

Why BACnet/SC is becoming increasingly important

Cybersecurity is now a central component of modern building automation.

BACnet/SC (BACnet Secure Connect) extends the international BACnet standard with modern security mechanisms such as:

• TLS encryption

• Certificate-based authentication

• Secure communication over IP networks

• Centralized management via BACnet/SC hubs

• Failover Strategies for Maximum Availability

However, these additional security measures place greater demands on the processing power and memory resources of the infrastructure in use.

This is exactly where the UBR-03 comes in.

Designed for large-scale BACnet/SC projects

The UBR-03 was designed for applications where standard routers reach their limits.

Typical applications:

• Office buildings and corporate headquarters

• Hospitals

• Airports

• Universities and Campus Solutions

• Industrial facilities

• Data centers

• Critical Infrastructure

Thanks to its powerful hardware, the router ensures reliable communication even with high data volumes and complex BACnet/SC topologies.

BACnet-certified for maximum interoperability

The UBR-03 has successfully received BACnet certification.

This means that the entire MBS UBR router family now has official BACnet certification. Operators, designers, and system integrators benefit from standards-compliant solutions and a high degree of interoperability between devices from different manufacturers.

The UBR-03 was developed by a company that has been actively shaping BACnet for decades. As a manufacturer, software developer, accredited BACnet testing laboratory, and active member of national and international trade associations, MBS has extensive experience in the planning, development, and validation of modern BACnet infrastructures.

When security becomes part of the infrastructure

BACnet/SC is changing the requirements for modern building automation. Encrypted communication, certificate management, and high-availability networks require high-performance components.

The UBR-03 was designed to reliably meet these exact requirements. This provides the necessary performance reserves for large BACnet/SC infrastructures—both today and in the future.

Real-world experience

“BACnet/SC has long since made the transition from theory to practice. Many of our customers now operate extensive BACnet/SC infrastructures. With the UBR-03, we are providing the necessary performance reserves for these projects and future cybersecurity requirements.”

- Nils-Gunnar Fritz, Managing Director of MBS GmbH
