Disclosed is an electromagnetically released spring pressure brake that is to be mounted on a machine wall or similar. Said brake comprises a uniform rectangular coil support (1) with two preferably oval, adjacent coils (7, 7.1), to which two separately movable rectangular armature disks are assigned. Said armature disks apply pressure to a joint rotor encompassing two friction linings that are mounted on each side when the coils (7, 7.1) are de-energized. The rotor is axially movable on an axially toothed hub. Two respective fastening screws (9) are used for guiding each of the armature disks parallel along the central longitudinal axis (13, 13.1) thereof, on the radially largest possible diameter of the rotor. A manual lever (10) featuring manual releasing bolts is provided for each armature disk. The inventive brake is simple and inexpensive and has two separate braking circuits, allowing the friction surfaces to be better utilized as the rotor has a greater diameter while the outer dimensions of the brake remain the same. Alternatively, the outer dimensions can be reduced if the rotor is not modified. In order to do so, a uniform or monolithic square coil support is provided that comprises two adjacent coils therein and two separate, independently movable armature disks on both sides of the central brake rotor (3).

Power supplies are known, in particular power supplies under primary clock-pulse control, that comprise a closed housing for the primary and secondary circuits, and a forced-air cooling means to cool the heat-producing components of the circuits. A power supply is proposed in which additionally there is a ventilation conduit in communication with the air outside the housing to serve as a cooling medium. The cooling means also comprises at least one cooling-unit element, on which the heat-producing components are mounted, and a portion of said element projects into the ventilation conduit and is electrically isolated by insulating means.
