Overview

The A7585D/A7585DU are high voltage regulators specifically designed for SiPM bias. Each has a built in temperature compensation controller with programmable coefficient. The module can be digitally controlled by UART and I2C. A7585DU moreover integrates a USB to UART bridge and it could be powered from USB. Output voltage could be also controlled proportionally to an analog input.
A7585D/A7585DU can provide up to 10 mA and the output voltage could be regulated between 20V and 85V with a resolution of 1 mV. Moreover, the ZEUS control software is provided for free; ZEUS allows to monitor and control multiple modules at same time.

Zeus Software
ZEUS is a Windows compatible software that allows to control multiple A7585DU modules using USB connection. The software is based on a user friendly GUI that allows the parameters configuration and the data logging on file. It integrates real-time plot capabilities (voltage, current and temperature) with the possibility to superimpose measurements from several modules.
ZEUS software is the simplest way to program temperature LUT compensation.

Moreover, a Python Library is available as well.

The Unit is developed in close collaboration with NUCLEAR INSTRUMENTS SRL.
