KVM Solutions for your individual requirements

KVM extenders - expand your possibilities

KVM extenders let you extend computer signals over IP or dedicated cables. This allows you to operate a computer from a workstation up to 10,000 meters away. Using KVM, you can easily separate computers and users to make your workstation more ergonomic and increase the security of your IT infrastructure. The systems consist of a computer module (CPU) and a console module (CON).

KVM switches - operate several computers by one console

Operate multiple computers with only one mouse, one keyboard and up to four screens and make your workplace more efficient and ergonomic. Switching between computers is done via buttons on the front panel, configurable key combinations or a serial device. KVM switches are often the basis for building redundant systems in different control room applications.

KVM matrix systems - for more flexibility and a better performance

Operate many computers via many workstations. Matrix systems consist of three components: a central module, computer modules (CPU) and console modules (CON). KVM matrix systems help you to operate complex IT infrastructures simply and intuitively. Benefit from the advantages wherever large distributed installations and decentralized operation and administration are required - e.g. in all kinds of control room applications.

Power for China's green Tech Megacity

Shenzhen Power Supply Bureau

One of the most vibrant metropolises in China, Shenzhen is considered the Silicon Valley of hardware. Around 80 % of all smartphones are manufactured in Shenzhen. It’s where tech giants like Apple, Huawei and Co. all produce their devices. Generally, the city seems to be the epicenter of inventions. As a pioneer for China, Shenzhen stands out for its extremely innovative developments and ways of thinking.

The main control room of the Shenzhen Power Supply Bureau has space for about ten employees. They monitor and control the remote computer technology, consisting of more than 500 powerful computers, around the clock. Therefore, all servers were moved to a technical area and connected to 20 KVM matrix systems from Guntermann & Drunck.
