3. Description of the mechanical parts
This section contains a description, from a mechanical point of view, of the parts which
constitute the SY1527 mainframe’s universal multichannel power supply system.
3.1
The SY1527 mainframe and its mechanical parts
The SY1527 system is hosted in an 8U-high, 19”-wide (84TE) EURO-mechanics rack.
The depth of the rack is about 720 mm.
The SY1527 mainframe can be essentially divided into four main mechanical sections
(refer to Fig. 2.1, p.9):
Board section;
Fan tray unit;
CPU and front panel section;
Power supply section.
Fig. 3.1 shows these mechanical components of the four sections in some further detail.
The higher 6U-high section of the mainframe’s rear part can host up to 16 boards, while
the lower 2U-high section contains the fan tray unit.
On the front part of the mainframe the higher 4U-high section hosts the front panel and
the CPU section, while the lower 4U-high section is devoted to the Power Supply Units
and to the Primary Power Supply (the latter is always located on the bottom right).
The mainframe structure is made of alodyne-treated aluminium which was chosen for its
high conductivity and light weight. Two panels cover the sides of this inner frame, while
the rear panel and the front panel complete the coverage of the structure. All the panels
are fixed with conductive screws in order to ensure electrical conductivity.
A description of each part can be found in the following sections.
