For critical applications within the process industry<\/a> (and increasingly from other sectors) it has long been common practice to use redundant power supply systems. Previously this has required 2 or more separate power supplies decoupled from each other using either diodes or for more sophisticated systems, redundancy modules. <\/p>\n\n\n\n\n\n\n\n

Wouldn\u2019t it be so much simpler to combine the power supply with the decoupling module into one article? That is exactly what we have done with the release of the new Plus version of the well-established QUINT power supply<\/a>. <\/p>\n\n\n\n

Initially\navailable as a 20A device ideal for process application, the new QUINT 20A Plus\npower supply is ATEX\/IECEx approved to both IEC 61508, and IEC 61511 standards,\nallowing the power supply to be mounted within potentially explosive areas (Zone\n2). <\/p>\n\n\n\n

With an integrated decoupling MOSFET and a\ndouble overvoltage protection (OVP) in the form of 2 separate protective\ncircuits, the plus version switches the output off quickly in order to protect\nthe consumer against over-votages.Operational safety is\nfurther enhanced by a protective conformal coating.<\/p>\n\n\n\n

A robust input is also a requirement for a\npower supply in a critical application and the powers supply features a mains\nfailure buffer time of at more than 20 ms and an integrated gas discharge tube\nfor high electrical noise immunity up to 6kV. To ensure that the output is\nmaintained the QUINT Power plus has both a static\nboost (up to 125% of the nominal current for a sustained period), as well as dynamic\nboost, (Up to 150% of the nominal current for 5s) ensuring heavy loads can be\nstarted easily. <\/p>\n\n\n\n

Last\nbut not least, often one of the requirements of the process industry is that\nthe power supply will operate reliably in very extreme conditions. I already\nmentioned the coated board meaning the device is protected against dust, gas\nand humidity but also thanks to the wide operating temperature range from -40\u00b0C\nto +75\u00b0C, the new power supply can also be used in the most extreme\nenvironmental conditions. <\/p>\n\n\n\n

Summary<\/h2>\n\n\n\n
  • The most powerful output side: reliable start-up of heavy load and miniature circuit breaker tripping even on long lines.<\/li>
  • The most robust input side: high noise immunity, thanks to integrated gas-filled surge arrester (up to 6 kV) and \u2265 20 ms mains failure buffer time<\/li>
  • Most comprehensive signalling: digital and analogue signals preventive function monitoring reports critical operating states before errors occur<\/li>
  • Can be ordered pre-configured: from a batch quantity of just 1<\/li><\/ul>\n\n\n\n

    So, the new QUINT Plus power supply from Phoenix Contact is the natural choice for critical applications and with SIL3 enables the user to achieve high operational safety, even for the most demanding applications.
