VME / Up to 6 kV

VME - NIM Power Supplies

Photo of VME / Up to 6 kV

The VME Power Supply family is a 6U modules family housing 6 independent High Voltage channels able to provide up to 6 kV and 3 mA. The units are available with either positive, negative or mixed polarity. The channels share a common floating return, which allows on-detector grounding reducing the noise level. HV outputs are delivered through SHV connectors. The HV output ramp-up and ramp-down rates may be selected independently for each channel in the 1 ÷ 100 V/s or 1 ÷ 500 V/s range with 1 V/s steps. The modules feature high Iset/Imon resolution (up to 1 nA). A Zoom feature is available for Imon, increasing resolution up to 100 pA. The modules fit into both VME/VME64 standard and V430 crates. Functional parameters can be programmed and monitored via VMEbus. A complete set of software tools is available to control these units, from low level libraries to graphical application software. Safety features allows the module to perform as a current generator and includes:

  • Channels: can be enabled or disabled through the Global Interlock logic. Channels individually enabled via front panel jumpers (passive or active mode available).

  • Overvoltage and Undervoltage warning: warning when the output voltage differs from the programmed value.

  • Overcurrent detection: when a channel attempts to exceed the programmed current limit, it signals an “overcurrent” condition and enters TRIP status. The output voltage is adjusted to keep the current below the programmed limit for a programmable TRIP time, after which the channel is switched off. If TRIP is set to “constant current mode”, the channel behaves as a current source.

  • Hardware VMAX and IMAX : maximum output voltage and maximum current value can be fixed, via front panel potentiometer, at the same common value for all the board channels. IMAX and VMAX values can be read out via software.

Software

Software Tools available (free download) to control the UP to 6 kV Family – V65xx:

 CAEN, in collaboration with CERN, has developed an OPC server which allows control of its power supply systems by any OPC compliant client application.
CAEN HV Wrapper Library It is a set of ANSI C functions bundled in a library, providing the software developer an unified software interface for the control of all the CAEN Power Supply products
GECO2020 CAEN General Control SW for High Voltage Boards and Systems. it can manage and control CAEN HV power supplies in any form factor as if they were an unique device.

HV channels into a VME-based DAQ system

The V65xx boards allow to integrate HV channels into a VME-based DAQ system: if you want the power supplies side by side with front end electronics in your VME crate, the V65xx boards are the way to go.
Modules control is guaranteed by the reliability of CAEN VME Bridges and the friendliness of CAEN Software tools: all data and parameters are easily organized and accessible on your desktop.
