In order to offer more LED step-down drivers with SELV (Safety Extra Low-Voltage) DC input (Class III) for the promising centralized low-voltage safety bus market, MEAN WELL has designed two series NLDD-H and LDDS-H LED drivers with direct current (DC) input voltage.
These two series have been designed to be applied in:
- 48V or 24V DC lighting equipment
- lighting products for DC bus applications.
The compact-sized Mean Well NLDD-H and LDDS-H series have a step-down design that converts the 48V DC input voltage into a constant output current and directly drives the LED modules.
The models 250/300/350/500/700/1050/1200/1400 mA are suitable for commercial track lighting or office interior lighting fixtures.
The NLDD-H series is available in two output connection modes:
- PIN for printed circuit
- Wire connection
The LDDS-H series, on the other hand, is available in one output connection mode:
The Mean Well NLDD-H and LDDS-H series are CE and EAC certified and comply with:
- EN61347 / EAC TP TC 004 lighting regulations and EN55015 / EAC TP TC 020 EMC
- SELV (<60V DC)
- Class III device regulations.
