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, 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 Control Board is 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 graphic color display featuring user-friendly 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 current-related hysteretic algorithm.
A different crate – i.e. SY3634T – with terminal output connectors and the AC mains ON/OFF switch is also available.
An EXTENDED voltage output version is available for the A3605BS, A3610BS and A3612BS modules. The output voltage range for these modules is rated at 40V and must be requested as an option.
The included free VISUAL software allows easily remote controlling the main features of A36xxBS modules using an intuitive Graphic User Interface (GUI).
