PULS UK Gains ATEX Approval for Full Range of Redundancy Modules

13 July 2011

PULS UK, the world’s leading manufacturer of DIN rail power supplies has been granted ATEX approval for its full range of redundancy modules, allowing them to be used in potentially explosive environments. Redundancy modules are used to back up critical devices in the event of the main source of power being interrupted. The units have been tested to EN 60079 – 15 and are approved for use in Class 1 Zone 2 Category 3G explosive atmospheres. PULS says no electrical changes were necessary to achieve the approval and that the Standard had been met in essence by dual conformal coating the internal components of the units. The six ATEX approved PULS modules, which range in output from 10A to 80A, will not increase in price despite the higher specification.

ATEX, which derives its name from the French

An explosive atmosphere is created when dust, mist or gases become mixed with the air and produce a flammable substance. Many industrial environments may contain, or have the potential to produce, an explosive atmosphere. Examples include places where production activities create or release flammable gases or vapour, such as paint spraying, or in factories handling fine organic dusts such as grain flour or wood.


'ATmosphère EXplosif' is the framework for controlling explosive atmospheres and the standards of equipment and protective systems used in them. By achieving EN 60079 – 15 approval PULS UK is now well placed to become a major supplier of redundancy modules in this important sector of the market.


PULS UK is a specialist manufacturer of DIN Rail power supplies and has developed some of the most advanced technologies for use within power supplies allowing them to achieve the highest efficiencies. PULS UK is a subsidiary of PULS GmbH, based in Munich, Germany. With three factories it is the second largest producer of DIN Rail power supplies in the world.
