Overview

The family of low voltage (LV) power supplies includes single width boards housing 6 or 8 individual floating channels. The boards are designed to provide maximum voltages from 4.5 to 15 V, with up to 1 mV set and monitor resolution.

The power supply boards A251x can provide output power up to 50 W per channel that can be connected in parallel with modularity 2 or 4 to obtain higher output power. Two possible front panels are available for these board families. Channels feature a PID (Proportional-Integrative-Derivative) digital controller, that allows to optimize the control loop to any load. The voltage drop over the cables can be recovered by using either the featured Remote Sensing Lines (A251x family), to be connected on the load for sensing the drop, or an automatic Line Drop Recovery system (the A151xB family is equipped with both features).

The boards are provided with both current and voltage protections. If overcurrent occurs, the relevant channel can be programmed either to turn off after a programmable trip time or to remain on and to provide the maximum allowed current. This particular feature allows the module to perform as a current generator. A global enable/disable connector allows to disable the channels and it is also possible, via front panel logic signals, to enable individually each channel.

The voltage ramp rates may be set independently for each channel. Moreover the individual floating channels allow on-detector grounding, thus allowing to reduce the noise level. Output channels are delivered through DB37 or D-sub 8 (on A251x family) connectors.

Universal Multichannel System - Mainframes

Modularity, Compatibility, Connectivity, Usability and Solidity are the keywords of the system design. The Mainframes have been specifically designed to power all detector technologies found in modern Physics Experiments, such as photomultipliers, wire chambers, streamers tubes, silicon detectors and others.

The systems are modular, flexible and match not only the requirements of major experiments with large number of channels but also the practical needs of test laboratories, where simple manual operations on a limited number of channels are often desired.

Software

A complete set of Software Tools is available (free download) to control CAEN Universal Multichannel Power Supply Systems, from low level libraries to graphical application software:

CAEN, in collaboration with CERN, has developed an OPC server which allows control of its power supply systems by any OPC compliant client application.
HiVoCS HiVoCS is a Web Interface available on any SY4527-SY5527 CPU. This Interface can be accessed directly via browser without installing any additional software.
EPICS IOC Mainframes CPUs integrates an EPICS Input / Output Controller (IOC) that provides access to the Process Variables using the Channel Access Protocol.
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.
