Explosion-proof SITOP devices for your occupational health and safety
A spark or hot surface can lead to serious industrial accidents in certain environments. In these environments, electronic devices must help ensure occupational health and safety by means of a special design and certificates. SITOP 24 V power supplies and add-on modules are therefore also available as Ex versions for zone 2, in which an explosive atmosphere can occur due to gases, vapors, or mist.
