Light up with LED power supplies
Published: 20 March 2012 - Michelle Winny
Two new families of LED lighting power supplies have been developed by Excelsys Technologies. The LDB75 and LDB100 constant voltage/current LED power supplies deliver up to 75W and 96W output power respectively, in compact packages.
The Xled products are low profile LED drivers delivering constant voltage single outputs of 24V, 36V or 48V. Both operate as constant-current drivers delivering the maximum output current range over the defined voltage range.
Standard features of the LDB75 and LDB100 include: universal input voltage 90-305VAC, constant voltage/current mode operation, high efficiency up to 91 percent, power factor typical of 0.95, waterproof to IP67, operating temperature range of -30 to 50°C, Class 2 device (UL1310) with LDB75 also Class II rated.
The range offers comprehensive protection to over-current, over-voltage, short-circuit and over temperature operation.
Typical applications for the new devices include in-store food display and mood lighting applications, outdoor signs, flat and wide screen street advertising displays, in-store media channels in retail shops, including hypermarts, supermarkets and convenience stores, high bay lighting for conference centres, hospitality industry and general industrial and retail building architectural lighting solutions.
