PULS UK, the world’s leading manufacturer of DIN rail power supplies has been granted ATEX approval for a selection of its single phase Q-series units, allowing them to be used in potentially explosive environments.

The units have been tested to EN 60079 – 15 and are approved for use in zone 2 hazardous systems category 3G.  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.

ATEX, which derives its name from the French '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 power supplies to this specialised sector of the market.

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. 

First shipments of the new Q-series units are expected in the United Kingdom in May 2010.
