Product Overview SY3634 Bipolar Power Supply Heterogeneous System High efficiency, low cost, high stability, easiness of configuration and maintenance are the key features of this new power supply (PS) system. Especially designed to operate in particle accelerator facilities, i.e. Synchrotrons and FELs. The system houses up to 4 independent current-controlled bipolar power supply modules. Different combinations of up to 4 modules (chosen among 5A, 10A, 20A or 30A) can be easily installed in the same rack. Extremely versatile and easy to “tune” to any load/magnet condition. Features • Digital feedback current control loop • Graphic color display OLED and an encoder per channel for local control • Up to 95% DC/DC power conversion efficiency • True bipolar zero-crossing operation • Ethernet connectivity • 8 (eight) independent external interlocks user-selectable • On-module speed-regulated fans • Internal temperature monitor circuits • MS Windows, Linux and MAC OS • Epics- and Tango-compatible Applications • Magnet Power Supplies • Current Waveform Generation • Accelerator Machine Power Supplies • Beamline Magnetic Experiments • Nuclear Magnetic Resonance (NMR) High efficiency, low cost, high stability, easiness of configuration and maintenance are the key features of this new power supply (PS) system, especially designed to operate in particle accelerator facilities like Synchrotrons and FELs. The system houses up to 4 independent current-controlled bipolar power supply modules, ranging from 5A to 30A, in a single 19-inch 3U standard crate (SY3634). Different combinations of modules (chosen among a catalogue including 5A, 10A, 20A or 30A channels) can easily be installed in the same rack. An auxiliary AC/DC converter module, the A3636 - SY3634, powers the control circuits. Each module implements a completely digital feedback control loop with a proprietary PWM generation technique: this makes the system extremely versatile and easy to “tune” to any load/magnet condition. Modules are composed by a Control Board (CB) and a Power Board (PB) that are mechanically connected: communication between boards is almost exclusively performed by digital signals that avoid possible analog signal corruption and undesired noise pick-up. The CB is mainly composed by a DSP that performs current control and an FPGA that supervises all processes like communications, diagnostic operations and interlocks handling. Remote communication is guaranteed by means of an Ethernet 10/100 auto-sensing socket present on each module front panel. The PS can also be locally monitored/ controlled via an encoder and a www.caenels.com graphic color display featuring userfriendly menus. An external DC bulk power supply feeds the PB power section and its ancillary parts. Cooling is performed by embedded fans, directly controlled by an output currentrelated hysteretic algorithm. Software and drivers are available for different operating systems like MS Windows, Linux and Mac OS; these devices are also Epics- and Tangocompatible.
