在一个elektroni8schen变压器或“转换器”，以电应力，例如从230伏降低到12伏，与单件式外壳，其中所述转换器可通过在一个室开口的壁或天花板面板提供到空腔的包层后面的开口被插入， 本发明提出的是，壳体具有两个部分，主部，其是大致圆形的，并具有设置在其具有比所述主要部分小的宽度，并且被形成为比主区域较浅的主区域杆的安装方向前方， 并且其被布置在相对高度偏移到主体部分，使得所述壳体具有从所述主区域至干高度在其下侧偏移的上升，以及设置在该壳体的电子部件被布置在两个或更多个水平高于另一个。

In a elektroni8schen transformer or "converter" to reduce electrical voltage as 230 volts to 12 volts, with a one-piece housing, the converter can be inserted through an opening provided in a wall or ceiling panel of a room opening into a cavity behind the cladding, the invention proposes that the housing comprises two portions, a main portion which is approximately circular, and, with, disposed in the mounting direction front of the main area stem which has a smaller width than the main portion, and which is formed shallower than the main portion and which is arranged offset in height relative to the main portion, such that the housing having a the stem rising from the main section height offset on its underside, and that arranged in the housing electronic components are arranged in two or more levels above one another.
