Series DD21 and DD22 power entry modules have been conceptually designed for PCB mounting. The DD21 product is equipped with multiple functions including inlet connector, switching, and fusing. In addition, the DD22 series offers standard or medical filter versions. The compact design of this series makes them ideally suited for use in low profile designs, especially 1RU enclosures for 19 in. racks. The DD series can be equipped with 1- or 2-pole fuseholders for 5 x 20 mm fuse-links. The 2-pole switch, which is designed for inrush current peaks of 100 A capacitive for 3 ms, is available in both illuminated and non-illuminated versions.
