This family of High Voltage Power Supplies includes boards housing up to 48 independent output channels designed to provide voltage up to 500 V and current up to 10 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 A1612, A1619 which are 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).
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 HV Ramp up/down rates may be selected independently for each channel in the 1 ÷ 50 V/s range (1 V/s step) for the A1619, while in the 1 ÷ 100 V/s range (1 V/s step) for the A1612, x542, x541 and x7042 boards.
The family is composed by three groups of boards detailed here below.
Features
From 12 to 48 independently controllable High Voltage channels
these boards house up to 32 independent High Voltage channels available with either positive, negative or mixed polarity and equipped with SHV or DB25 connectors. The maximum output current is 10 mA, (200 nA step) with 10 nA monitor resolution for the A1541, 1 mA, (20 nA step) with 1 nA monitor resolution for the A1542 and 1 mA / 100 µA (20 nA steps) for the A1542H. Mixed versions with 6/12 positive and 6/12 negative channels are also available.
A7042 is the new line of high density general purpose power supplies offers 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 Radiall Multipin or DB37 connector. The maximum output current is 500 μA, with up to 1 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.
A1612 / A1619
These boards house 16 independently controllable full floating channels with dual current range. The output voltage provided is up to 250 V (A1619) or 500 V (A1612) with 10mV set/monitor resolution. The output channels offer dual current ranges (software selectable):
High power: maximum current: 1 mA / 10 nA monitor resolution.
High Resolution: maximum current: 100 µA / 1 nA monitor resolution
The voltage ramp rates may be set independently for each channel. The fully floating channels allowing on-detector grounding, which allows on-detector grounding reducing the noise level.
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.
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 is a Web Interface available on any SY4527-SY5527 CPU. This Interface can be accessed directly via browser without installing any additional software.
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
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.
