Filtered DC power entry module meets tough demands for EMC

17 May 2006 Interconnection

Schurter's 5003 series filtered power entry module is a new, compact filter designed for DC power supplies used in IT equipment. It features a standard DC connector, offered in two different connector styles. The connector is encased with a 1-stage filter for rated currents of 3, 6, 10 and 15 A. It provides a superior wide-band absorption rate in frequencies ranging from 100 kHz to 30 MHz.

The unit mounts to the equipment enclosure with a metal flange, thus providing a large contact area for optimal shielding of the panel opening. A version for front or rear mounting is secured using screws and nuts, or rivets. A version specifically for rear mounting, features pre-formed, threaded holes for M3 screws. This version eliminates the handling of nuts, reducing costs and automating assembly. The 5003 fulfils the requirements of IEC/EN/UL 60950 for use in IT equipment, and is pending certification according to UL/CSA up to 15 A at 125 V d.c. Applications include LAN and WAN devices, such as routers, switches and multiplexers.
