This family of High Voltage Power Supplies includes single and double width boards housing up to 16 output channels. The boards are designed to provide voltage up to 15 kV and current up to 1 mA.
All the boards are compatible with all CAEN Universal Multichannel Power Supply Systems. The available grounding option, depending on the family are the following: Common Ground (AGxxxx) or Common Floating Return (Axxxx). 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 A1523, A1524 and A1526 boards feature the CPE HV output connectors and the relevant coaxial cable connectors (Mod. A997) are also available.
The HV ramp-up and ramp-down rates may be selected, for each channel, in the 1 ÷ 500 V/s range (1 V/s step).
The boards are provided with both current and voltage protections. If overcurrent occurs, the relevant channel can be programmed either to turn of 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. Channels may be enabled or disabled via the Interlock logic. The voltage ramp rates may be set independently for each channel.
The maximum output voltage can be fixed, through a potentiometer located on the front panel, at the same common value for all the board channels and this value can be read out via software.

The CAEN A1590 board is a double width module (10 TE wide) that houses 16 Independent high voltage channels delivered through Radiall 52 pin HV connectors. The board is available with either positive or negative output polarity. The output voltage range is 0 ÷ 9 kV with 10 mV set and monitor resolution while the Maximum output current is 50 μA with 100 pA monitor resolution.
These models are double width (10 TE wide) boards that houses 6 independent high voltage channels, available with either positive, negative or mixed polarity (A1523 only). The output voltage can be programmed and monitored in the 0 ÷ 12 kV range with 1 V resolution. The maximum currents are:
The CAEN A1526is a double width board (10 TE wide) specifically designed for the single gap RPC detector. Available for positive and negative polarity, it features 6 independently controllable HV channel equipped with CPE or Kings connectors. The output voltage can be programmed and monitored in the 0 ÷ 15 kV range with 1 V resolution. The current full scale can be fixed via internal jumpers either at 100 μA or at 1 mA.
A global enable/disable connector allows to disable the channels when it is not terminated on 50 Ω.
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.
