Overview

A7460 The Mod. A7460 is a 12 channel HV board, available with either positive or negative polarity, compatible with the CAEN Universal Multichannel Power Supply System (SY1527, SY2527, SY4527, SY5527). The A7460 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.
The output voltage range is 0 ÷ 6 kV, with 1mA/100µA dual range maximum output current and 10mV set and monitor resolution. Maximum output power is 6W per channel.
The boards are provided with both current and voltage protections.
Two output current limits are foreseen:
• ISet; software limit, individually set for each channel; if exceeded, the relevant channel is signalled in Overcurrent
• IMax; hardware limit, common to all channels, set via front panel trimmer and monitored via software; if exceeded the relevant channel can be programmed either to turn off after a programmable trip time or to keep on providing the maximum allowed current: this particular feature allows the module to work as current generator.
The maximum output voltage can be fixed, through a trimmer located on the front panel, at the same common value for all the board channels and this value can be read out via software. The boards have also the safety board interlock.
The HV RAMP-UP and RAMP-DOWN rates may be selected independently for each channel in the 1 ÷ 500 V/s range (1 V/s step).
