150 and 200 Watt LED power supplies in IP67-rated 198x63x35mm housing
June 19, 2012 // Julien Happich
Excelsys Technologies' LDB 150 LED and LDB 200 power supplies provide 150 watts and 200 Watts of constant current/constant voltage power respectively in an IP67 rated, low profile, aluminium case.
Measuring only 198x63x35mm with the UL8750 and CE markings, 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, an MTBF of 1,000,000 hours per Telecordia SR-33 and both models are backed by a 5 year warranty. Custom output voltage and output current set-points are available for OEM applications.
