Filtered Power Entry Module Offers Extended Mounting Options

SCHURTER expands its power entry module series DD12 with screw and snap mounting options. An integrated ground line choke for suppressing high-frequency interference on the ground conductor is also a newly featured option.


The DD12 all-in-one fuse holder, switch and EMC filter offers remarkable functionality in a very compact housing. It combines an IEC C14 appliance inlet with a 1- or 2-pole fuse holder, ON/OFF switch, and standard or medical low leakage filter. The wide metal flange (horizontal or vertical), or metal snap arms for panel thickness up to 8 millimeters, optimizes filter and shielding effect.

Audio equipment for instance is known for being prone to ground loop problems. Often referred to as hum or buzz, the DD12 with ground line choke is well suited for suppressing interferences that lead to diminished sound quality. The DD12 is also well suited for medical equipment required to use low leakage filters for increased patient safety according to IEC 60601-1. The ground line choke helps to improve upon the asymmetric attenuation due to the reduced Y capacitance. Other applications include equipment that requires particularly high immunity such as IT equipment according to IEC 60950-1.


The DD12 series is certified for currents up to 10 A/250 VAC according to IEC and 8 A according to UL/CSA at 125/250 VAC. It is ENEC and cURus approved. Pricing for the DD12 complete with fuse drawer starts at $23.12 each/100. For more details, peruse the DD12 datasheet, call 800-848-2600, and/or email [email protected].
