The CAEN Multichannel Power Supply System Overview
The SY1527 system is the fully equipped experiment version of a new line of power
supply systems which represent CAEN's latest proposal in the matter of High Voltage and
Low Voltage Power Supplying. This system outlines a completely new approach to power
generation and distribution by allowing the housing, in the same mainframe, of a wide
range of boards with different functions, such as High/Low Voltage boards, generic I/O
boards (temperature, pressure monitors, etc.) and branch controllers, where the latter are
used to control other remote generators and distributors. Modularity, flexibility and
reliability are the key-points of its design, enabling this module to meet the requirements
needed in a wide range of experimental conditions, which range from those of LHC
experiments, where the features of this model find prior application, to those of other less
challenging, but still demanding, High Energy Physics experiments.
The mainframe is housed in a 19"-wide, 8U-high euro-mechanics rack and hosts four
main sections:
-
the Board Section, with 16 slots to house boards, distributors and branch controllers;
-
the Fan Tray Section, housing 6 fans arranged on two rows;
-
the Power Supply Section, which consists of the primary power supply and up to 3
power supply units;
-
the CPU and Front Panel Section which includes all interface facilities.
The User Software Interface features the usual friendliness of the previous CAEN
systems which now also includes a 7.7" colour LCD. A wide choice of interface facilities
provides full communication compatibility with the previous systems and the feasibility of
controlling heterogeneous external devices. Modularity has been one of the leading
criteria in the design and development of the system: both the Power Supply Section and
the Board Section are completely modular. The Power Supply Section allows different
configurations with up to 3 power supply units per mainframe (up to 2250 W), while the
Board Section can house up to 16 boards able to fulfil different functions. A complete line
of power supply boards and distributors has been specially developed for this new
system. The minimum system configuration consists of the primary power supply, one
