SCHURTER expands its wide range of power entry modules for use in protection class II applications. The new version is perfectly suited for medical equipment used at home where the medical standard prescribes the use of protection class II design.
In contrast to protection class I equipment, which is connected to a protective conductor, protection class II equipment generally has no metal case.
The new KMF class II version is according to IEC 60320-1, style C18 without ground wire.
This category of equipment called double insulated and requires higher safety levels for energized components relative to exposed surfaces. The KMF class II power entry module provides double insulation between energized components and exposed parts. This reinforced insulation is tested with a voltage of 4000 VDC between the energized conductor (L) and the neutral conductor (N) relative to the mounting panel.
The KMF module is available with 2-pole line switch, and 1- or 2-pole fuse holder.
For medical applications is an "extra-safe" fuse holder available, that can only be opened with the aid of a tool. The filter is available as Medizinal M5 version with very small leakage current.
The integrated filter at the power input provides highly effective interference suppression. This affects optimal on the electromagnetic compatibility.
The KMF sclass I and class II are for currents from 1A to 10A at 250 VAC according to IEC and UL standard. They are ENEC, cURus and CCC approved and suitable for applications according to IEC 60950th.
