To offer the market even more options for SELV step-down DC / DC LED drivers (Class III), MEAN WELL has developed and launched mass production of two new series, NLDD-H and LDDS-H.
NLDD-H and LDDS-H are compact DC / DC power supplies that convert 24 / 48 V DC input voltage into a stabilized current of 250 / 300 / 350 / 500 / 700 / 1050 / 1200 / 1400 mA depending on the model.
The NLDD series can be mounted in the luminaire with wires or directly on the board (depending on the model), while the LDDS-H series can only be mounted with wires. Although this equipment is low-voltage, MEAN WELL has certified it for CE and EAC, including compliance with the lighting requirements of EN61347 / EAC TP TC 004 and EMC EN55015 / EAC TP TC 020 standards, as well as SELV compliance (<60 V DC).
