SCHURTER has expanded its range of power entry modules to include versions, without ground pin, for use in Protection Class II double-insulated applications.
The DC12 power entry module is already used in Protection Class I equipment, due to its high performance switch and EMC filter functions integrated into one compact package.
The new Protection Class II version is perfectly suited for medical equipment used at home where the medical standard prescribes the use of Protection Class II design.
The new DC12 Class II version is according to IEC 60320-1, style C18. It is particularly well suited for use in medical equipment according to the IEC standard 60601-1-11, which outlines additional safety measures specific to medical equipment intended for use in the home. There is increasing demand for such equipment as populations around the world age and healthcare costs continue to rise. Protection Class II equipment, in contrast to Protection Class I equipment, generally has no metal case. This category of equipment is called double insulated, and requires higher safety levels for energised components relative to exposed surfaces.
The DC12 Class II power entry module provides double insulation between energised components and exposed parts. This reinforced insulation is tested with a voltage of 4000 VDC between the energised conductor (L) and the neutral conductor (N) relative to the filter case. The DC12 line switch is available in 1- or 2-pole and touts high inrush current withstand capability. The EMC filter is available in medical and low leakage, M5, versions. This integrated filter at the power input provides highly effective interference suppression, which results in optimised electromagnetic compatibility.
Current ratings range from 1-10 A at 250 VAC. Versions with quick-connect or solder terminals are available. The DC12 is available in black or white. Mating V-Lock cord sets are available to safeguard against unintentional disconnection of the power. The DC12 Class I and Class II are ENEC and cURus approved. They are suited for use in equipment according to IEC 60950, IEC 60601-1, in addition to IEC 60601-1-11.
