Description
MEAN WELL NLDD-H and LDDS-H DC/DC LED Power Supplies are DC input LED drivers that can be applied to lighting equipment within the 48VDC or 24VDC range or used with lighting products for DC bus applications. MEAN WELL NLDD-H and LDDS-H DC/DC LED Power Supplies have a step-down design, converting 48VDC input voltage into constant current output and then directly drive LED modules. With a variety of output currents, they are suitable for commercial track lighting or office indoor lighting luminaires. NLDD-H provides PIN style and wire style output connection while LDDS-H offers wire style only. These devices comply with lighting regulations EN61347/EAC TP TC 004 and EMC EN55015/EAC TP TC 020 and comply with SELV (<60VDC) and Class III.
