It is typical that transient voltage surges from both external and internal sources directly affect the performance and life expectancy of electronic equipment. Products having a printed circuit board inside, from electronic lighting ballasts to computer servers, may be susceptible to transient voltage surge damage. As microprocessors and components that make up this equipment grow smaller and faster with each new generation, their susceptibility to transient voltage surge damage becomes ever greater.

The full-featured Tranquellâ„¢ DIN Rail Mount SPD (Surge Protective Device) is a Type 2 surge protective device that is modular and easy to install. DIN Rail mount housing allows for quick installation. Each unit has a compact footprint and user-replaceable phase surge pluggable modules with an IP20 finger-safe design. Both visual indicators and remote indicators (dry contact) provide SPD status to critical control circuits.
