The Power Supply Section allows different configurations with up to 3 power supply units per mainframe up to 2250 W while the Board Section can house up to 16 boards able to fulfil different functions A new line of boards and distributors analogous with those available for the SY527 system and a set of branch controllers has been specially developed for this new system The minimum system configuration consists of the primary power supply one Power Supply Unit and one board The concept of modularity has been extended up to the possibility of arranging clusters constituted by one intelligent SY1527 system able to drive other non intelligent Systems i e systems without CPU to be implemented The connections among the systems constituting the cluster are realised through a new CAEN interface the Local Net The extreme system flexibility which allows to house indifferently inside the same mainframe boards with different functions is further enhanced by the possibility of developing ad hoc boards and even complete custom peripheral systems The latter actually can be designed specifically for on detector installation All the custom electronics can be however remotely controlled by single boards which are inserted in the SY1527 mainframe and act as branch controllers Fast accurate set up and monitoring of system parameters 14 bit resolution on Voltages and Currents with standard boards is available for each branch controlle
