Overview

The SY127 is a High Voltage System featuring modularity and high flexibility. The System has been designed to power a wide range of detectors and is suitable for both major experiments and for the laboratory tests.
It consists of one Std. 19" Euro Crate that houses a Control Unit on the front side, and ten slots for HV plug-in Channels (Model A 300 - A 400 - A 600) on the rear side.
The SY 127 features a powerful software with a friendly User interface, together with sophisticated overvoltage and overcurrent protections.
The SY127 can be locally monitored and controlled via on-board alpha-numeric keypad and display. Remote control is possible via RS232C port and HIGH SPEED CAENET (with either PCI card Mod. A1303, or VME board Mod. V288). Thanks to the communication controller Mod. A128HS, it is possible to upgrade older systems, previously controlled via HV CAENET, to HS CAENET (please check with CAEN firmware compatibility of older SY127 systems).
