CBM – Protecting Your Application

From |

The Industrial Internet of Things (IIoT) is the use of Internet of Things (IoT) technologies in manufacturing. The fundamental driving philosophy behind IIoT is to build smart machines. The emphasis is placed on the topic of big data, sensor information and communications.

With data captured across all processes, it has enabled companies to analyse and anticipate on inefficiencies and issues immediately, thus saving time and money.

Typically in a switching system, its core function is to control and switch various kinds of devices and machines.

What’s common to all of them is that the demands placed on the components are very high. When a machine is running 24/7, the chances of the machine breaking down is very likely. Hence, extra attention is needed to ensure availability of the machine operations. In any case of the machines breaking down, the operation must be restarted in the fastest possible time.

Phoenix Contact’s CBM electronic multichannel DC device circuit breakers offer extended protection against over load and short-circuit currents on the connected applications.

Thanks to the integrated nominal current wizard, setting the right nominal current for your loads is hassle-free!

The selected settings are locked electronically to prevent any risk of unintentional adjustment.

The integrated early preventative warning system ensures fewer failures.

In the event that 80% of the set nominal current of a channel is reached, a warning is indicated via the associated on board LED. Furthermore, the separate signal output can be used for remote signalling.

Thanks to the active current limitation, the upstream power supply can be used optimally. This enables the use of smaller switched-mode power supply units and prevents undesirable voltage dips.

So what are you waiting for?

Ensure that your operations are running continuously and without fault.

Sleep with ease tonight, every night.

Powerful PV overvoltage protection

From |

The new VAL-MB product family from Phoenix Contact provides powerful and compact protective devices for photovoltaic applications with generator voltages of up to 1500 V DC. The protective devices are specially adapted to DC application requirements and certified by KEMA.

Longer inlet funnels and higher screw shafts provide additional protection against arcing. The product range includes protective devices for generator voltages of 600 V DC, 1000 V DC and 1500 V DC, as type-1/2 lightning current arresters, as well as pure type 2 surge protection devices. Variants are available with or without remote signaling contact. All protective devices have a short-circuit protection of 2000 A and can also be used in high-altitude plants up to 6000 meters in altitude.
