Overview
A1539 / A154x is a new family of HV Power Supply Boards providing 32, 24 or 12 independent high voltage channels available with either positive, negative or mixed polarity compatible with CAEN Universal Multichannel Power Supply Systems (SY1527, SY2527, SY3527, SY4527, SY5527).

CAEN provides 2 different channel grounding: AG5xx (Common Ground) and A15xx (Common Floating Return). 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 boards are available in different versions equipped with SHV or DB25 connectors.

The output voltage range is 0 100 V (A1539/40/40H - AG539/40) or 0 500 V (A1541/42/42H - AG541/42) with 1mV monitor resolution.

The maximum output current are 1mA (A1540/42 - AG540/42), 10 mA (A1539/41 - AG539/41) or 1 mA/100 A (dual range boards: A1540H, A1542H)

Safety features A1539/A154x
Safety features
arrow Channels can be enabled or disabled through the Global Interlock logic.
arrow Overvoltage and Undervoltage warning when the output voltage differs from the programmed value.
arrow Overcurrent detection: when a channel attempts to exceed the programmed current limit, it signaled to be in "overcurrent" and enter in a TRIP status. The output voltage is varied to keep the current below the programmed limit for a programmable TRIP time, then the channel is switched off. If TRIP is set to "constant current mode", the channel behaves like a current generator.
arrow Hardware VMAX: maximum output voltage can be set via front panel potentiometer, at the same common value for all the board channels. VMAX value can be read out via software..
arrow Safety Board Interlock: this protection disables the HV generation when the HV outputs are not connected to their loads (only for Multipin DB25 Connector versions).
Mainframes
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.
