Elmdene claims rigorous in-house testing demonstrated impressive efficiency levels of up to 95% – 5% above its predecessor EN54-4 and favourable in comparison with 50%-55% levels typical of many PSUs using older linear technology
Four power variants – 1A, 2A, 5A and 10A – each deliver 27.6V dc output
All models certified to EN54-4:1997, A1:2002 and A2:2006
Mains and battery monitoring with independent volt-free outputs
battery deep discharge protection in the event of a mains failure and LED indicators to support quick diagnosis of power supply’s status.
For installers: Variety of enclosures available, giving installers the widest possible choice of standby battery back-up options, all the way from 1.2Ah to 65Ah.
Innovation: Intelligent battery charging thanks to the company’s “ultra-efficient”, proprietary EcoCharge capability, which unlike standard power supply charging circuits that continuously trickle-charge their standby batteries, checks battery power every 24 hours, only topping up when required. Battery life is thus increased and running costs reduced.
Manufacturer says: “We believe that with certification to EN54-4 and the industry-leading features built-in to the STX range – from switch mode technology to our own EcoCharge functionality which brings a considered approach to battery charging – that these new models are well placed to grow our presence in the fire system PSU market,” says Elmdene MD Ian Moore.
“Not only can they deliver reliable load and standby power, and the fault monitoring required by the fire control panel, but, crucially, are able to push the envelope in terms of operational efficiency, from how the power supply itself generates energy to the extended life of any associated batteries, with all the benefits that this unlocks for a user’s, all important, cost of ownership.”
About the manufacturer: A subsidiary of Potter Electric Signal LLC, Elmdene International Ltd manufactures electronic products for security, access control, CCTV and fire industries around the world.
Established more than four decades ago the Portsmouth-based company’s products include power supplies, external/internal sounders and magnetic contacts as well as a range of ancillary products.
