child1 A1560H / A1580H
The A15x0H is a new CAEN family of HV Power Supply boards, available with either positive, negative or mixed polarity, compatible with the CAEN Universal Multichannel Power Supply System (SY1527, SY2527, SY3527, SY4527, SY5527). 8 and 16 channel version are available; all models feature individual channel enable.

The HV channels share a common floating return, which allows on-detector grounding reducing the noise level; the floating return is insulated from the crate earth up to ±50 V (with 65 V hardware limit).

The output voltage range is 0 ÷ 6 kV (A1560H) or 0 ÷ 8kV (A1580H), with 10 mV monitor resolution. The maximum output current is 20µA, with 50 pA monitor resolution.

A1560H and A1580H are supplied in different versions equipped with SHV or with Radiall Multipin connector

Safety features
arrow Channels can be enabled or disabled through the Global Interlock logic.
arrow Remote Enable/Disable: front panel independent contacts available for all channels.
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 Connector versions).
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.
