Pepperl+Fuchs’ New M-LB-2000 System Easily Protects Against Surge Transients

Worldwide, there are nearly 50 lightning strikes every second, almost 1.4 billion strikes per year. Overvoltage due to lightning strikes or switching operations is one of the most common causes of electronic damage, to which the process industry is very vulnerable. Surge protection concepts are therefore crucial to plant and personnel safety. The new M-LB-2000 system from Pepperl+Fuchs―the experts in explosion protection―provides just such protection.

ABB: Arc Guard System TVOC-2

The arc flash is one of the most dangerous incidents in electrical installations that could cause severe harm to people and equipment involved. When an arc flash occur, time until arc interruption is one of the most critical factors since it is directly proportional to the amount of energy released. The arc flash incident energy will in turn determine how much damage an arc flash will cause.

Emerson Uninterrupted Power Supply Maximizes Machine Availability and Minimizes Unplanned Disruptions in Harsh, High Temperature Industrial Environments

As more power-sensitive devices are deployed in automated industrial processes, the need for reliable battery backup power is growing exponentially, yet serious challenges remain in the design of traditional Uninterrupted Power Supplies (UPS). Most UPS are simply too large or heat-sensitive to be installed in control cabinets or to be integrated into machines, and virtually all lack network communications required for remote diagnostics.
