The latest Vision PSUs (Power Supply Units) from Elmdene, which were premiered at the recent Ifsec 2011 security exhibition, comprise the low profile VRS12-6000 and the encapsulated VRS12-3500 EB models. Both of these Switch Mode options are designed to deliver regulated 12v dc outputs with a universal mains supply voltage of 100v to 253v.

The Vision range has been specifically developed by Elmdene with the rigorous demands of CCTV installations in mind and to ensure the efficient and reliable operation of surveillance cameras and associated equipment. In addition to the new 12v units customers can also select from a wide range of 24v models for CCTV-specific applications.

Said Ian Moore, Managing Director at Elmdene International Limited: “We are pleased to be able to announce the expansion of the Switch Mode power units in our Vision range, underlining as it does Elmdene's strong commitment to 'green' power technology. There is certainly a growing awareness of the economic benefits which customers can realise from adopting Switch Mode units to power their CCTV devices, as well as helping to meet their corporate environmental obligations.

“The advantages of Switch Mode technology are certainly brought into sharp relief when the typical efficiency of linear power supplies, at 50–55%, is contrasted with that of the latest Switch Mode models which can reach between 80-87%. This is a dramatic difference. In addition, as Switch Mode units build-up less heat during operation they can potentially deliver heightened reliability, have a longer life in the field and are less likely to interfere with other devices.”
