New on-board DC-DC converters

27 June 2007 Power Electronics / Power Management

Mean Well has launched the NSD-10 (10 W) and NSD-15 (15 W) series on-board type DC-DC converters that expands its DC/DC product lines in the low wattage range for the emerging trend of distributed power applications. Replacing its previous ASD-10H and ASD-15H, the new NSD series maintains the same dimensions and pin assignments, but improves the performance and reduces the costs.

Featuring a 4:1 wide DC input range and 1500 V d.c. input/output isolation, the NSD10/15 series both have two kinds of DC input level - 12 V, 48 V, and eight kinds of DC output level - 3,3 V, 5 V, 9 V, 12 V, 15 V, ±5 V, ±12 V, and ±15 V for end users to select from (the NSD15 does not have the 9 V output).

Standard functions include remote ON/OFF control, short-circuit, overload, and over-voltage protections. The 15 W models also have an output voltage trimming function that gives users more flexibility to the system design.

These units are suitable for applications using distributed power architecture that transfer the high DC bus voltage to lower DC working voltage at the location of the load. Approved to UL/CUL/CE, the 10 W unit measures 50,8 x 25,4 x 10 mm, and the 15 W unit measures 50,8 x 38,1 x 9,82 mm (15 W).
