A1539 – A1540(H) – A1510 – A7040

Universal 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.

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
