Compact power entry modules
4 February 2009
Interconnection
Schurter recently added the new DD11 and DD12 power entry modules to complement the existing snap-in and PCB mount counterparts. The new addition with mounting flange is offered for applications requiring screw mounting to the panel.
The DD series provides up to four functions packed into a 49 x 30 mm space-saving package. The additional mounting flange supports horizontal mounting, thereby optimising space while providing maximum functionality. The inlet portion of the unit (according to IEC 60320-1, style C14 or C18), integrates a fuse holder, switch and optional standard or medical EMC filter.
The DD series is especially suited for medical applications, designed to comply with IEC 60601-2. The fuse drawers are offered as 1- or 2-pole and accept five x 20 mm fuses. A safety feature prevents users from removing the fuse drawer while the power cord is plugged into the equipment. The medical filter limits leakage current to 5 or 80 μA for the DD11 and DD12 respectively.
An M80 version provides increased attenuation of electromagnetic interference, yet still meets the leakage requirements for non-patient contact devices. The 2-pole switch offers an inrush current peak of 100 A capacitive for 3 ms and is available in both illuminated and non-illuminated versions.
