The SY4527 system is the fully equipped experimental 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. 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; “Low cost” version with 10 slots is available (NEW)
- the Fan Tray Section, housing 6 fans arranged on two rows, with programmable rotation speed regulation;
- 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 CPU controller is available in 3 different versions: BASIC, ADVANCED and FULL.
- The BASIC version provides all the communication interfaces, the RESET control, the INTERLOCK control and status LEDs.
- The ADVANCED version also provides the beam handshake management connectors (CH-ON, GEN, VSEL, ISEL).
- The FULL version provides the complete set of panel connectors, the ENABLE control section, and the fan speed control.
The Power Supply Unit (PSU) is also available in three versions: PRIMARY, OPTIONAL SINGLE and OPTIONAL DOUBLE.
- The Primary PSU (A4531) is the standard SY4527 power supply block. It includes the SERVICE and 600W PSU within a single slot module. The SY4527 includes one A4531 Primary Power Supply
- The Optional Single PSU provides an additional 600W of power in a single slot module
- The Optional Double PSU provides an additional 1200W of power in a single slot module
Please note: The PRIMARY PSU will be providing power to the boards installed into the mainframe as well as to the motherboard control electronics (CPU). When configuring the SY4527 power output customers should take this factor into consideration. For some applications, especially those which include Low Voltage/High Amperage boards, the power requirement must be carefully considered to avoid failures and maximum component life expectancy. For configuration questions or concerns we recommend that you contact your CAEN representative and/or technical support.
The User Software Interface features the usual friendliness of the previous CAEN systems which now also can optionally include a colour touchscreen LCD (10.4″ and 5.7″ available). 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 4 power supply units per mainframe (up to 4200 W), while the Board Section can house up to 16 boards able to perform different functions. The complete line of power supply boards and distributors that has been specially developed for SY1527 are fully compatible with the new mainframes.
The minimum working system configuration consists of the primary power supply, one CPU controller and one board. The system allows also to deal with power supply solutions composed by “branch controllers” (housed in the system mainframe) and on-detector “remote boards” (manufactured in order to be magnetic field and radiation tolerant). A sophisticated trip handling via software allows to control and correlate trip conditions on the channels of the crate. Live insertion and extraction of the boards, which reduces the down time of the global system and eases access to the computing core and peripherals of the system, complete the system flexibility.
Easy interfacing is another key-point of the SY4527 system. The Gigabit Ethernet interface (and the optional Wi- Fi interface) allows both an easy web access and the connection via OPC Server to a SCADA control system. Enhanced software programming features a unified command set independent from the interface used to communicate with the system. The Power Supply Section and Board Section can be externally synchronised via front panel connectors. Handy maintenance and upgrading, which constitute a major issue in the reliability of a system, are further guaranteed by the possibility of accessing and servicing the system via network facilities.
The new SY4527 beneficial of a complete set of Software Tools to control the unit and all the parameters of the High Voltage and Low Voltage boards, from low level libraries to graphical application software.
In addition the advanced version of the GECO2020 software introduces Logging and Scripting Capability.
The Logger is a useful tool which records every command sent to the system and every warning/alarm detected by the system. In this way it is possible to automatically monitor the behavior of every single parameter during operations. Complex and advanced commands can be managed through the Scripting capability. Based on a simple proprietary syntax, this tool ensures flexible and fully customizable control on every system and board aspect.
