Excelsys Technologies LDB 150/LDB 200 power supply range

Excelsys Technologies has introduced the LDB 150 LED and LDB 200 power supplies that provide 150 and 200 W at constant current/constant voltage power in an IP67-rated, low-profile, aluminium case.

The series features two models offering 24 or 48 V nominal output. 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 90-305 VAC with active power factor correction with high-efficiency operation up to 92.5% make these units suitable for ‘green’ lighting applications.

Additional features include -30 to +70°C operating temperature, built-in overcurrent protection, overvoltage protection, overtemperature protection and short-circuit protection, high line and load regulation.
