Excelsys Technologies has introduced the latest models in the Xled series of LED power supplies.
The LDB 150 LED and LDB 200 power supplies provide 150W and 200W of constant current/constant voltage power respectively in an IP67 rated, low profile, aluminium case measuring 198 x 63 x 35mm with UL8750 and CE marked.
The LDB150 and LDB 200 series each feature two models offering 24V or 48V nominal output voltages.
The units offer constant voltage operation up to their full load capability and then constant current operation down to 50% of their nominal output voltage.
An extended universal AC input range of 90-305VAC with active power factor correction with high efficiency operation up to 92.5% make these units ideal for “green” lighting applications.
Additional features include -30 to +70°C operating temperature, built-in over-current protection, over-voltage protection, over temperature protection and short-circuit protection high line and load regulation and an MTBF of 1,000,000 hours per Telecordia SR-33. Custom output voltage and output current set-points are available for OEM applications.
Typical applications for the new series include outdoor signs, street and roadway lighting, high bay lighting, flat and wide screen street advertising displays, in-store media channels in retail shops, including, supermarkets and convenience stores and general industrial and retail building architectural lighting solutions.
