Universal Multichannel System

Home Power SupplyUniversal Multichannel System Up to 100 V

This family of high voltage power supplies includes boards housing up to 48 independent output channels designed to provide voltage up to 100 V and current up to 20 mA.

All the boards are compatible with all CAEN Universal Multichannel Power Supply Systems and are available with two different grounding options: Common Ground (AGxxxx) or Common Floating Return (Axxxx) excluding the A1510 board which is Fully Floating. Common Floating Return allows on-detector grounding reducing the noise level; the floating return is insulated from the crate earth up to ±50 V (with a 65 V hardware limit).

The HV Ramp up/down rates may be selected independently for each channel in the 1 ÷ 50 V/s range (1 V/s step).

All the boards are provided with both current and voltage protections. If overcurrent occurs, the corresponding channel can be programmed either to turn of after a programmable trip time or to keep on providing the maximum allowed current. This feature allows the module to perform as a current generator.

The channels can be enabled or disabled through the Interlock logic. The voltage ramp rates may be set independently for each channel. The costumer can choose between different channel grounding.

The family is composed by three groups of boards detailed here below.

From 12 to 48 independently controllable HV channels
0–100 V output with up to 1 mA or 10 mA max current (dual range available)
Very high set/monitor resolution and ultra-low ripple (< 3 mVpp)
Individually programmable voltage, current limit, ramps, and TRIP parameters
Multiple connector options, polarity configurations, and grounding schemes

A7040

The CAEN A7040 is the new high density general purpose power supply offering you all the safety, performance and control of a completely independent channel technology at the cost effective price of a distributor. Well suited for large Silicon detectors arrays, this family house 48 independent High Voltage channels available with either positive or negative polarity, equipped with DB37 connector. The maximum output current is 1 mA, with 2 nA monitor resolution. The maximum output voltage can be set through a potentiometer to a value which is common to all channels and can be read out via software.

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:

OPC Server	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.
