Overview
The DT5485P is a high voltage regulator specifically designed for SiPM bias. It has a built in temperature compensation controller with programmable coefficient (3.5mm audio socket for temperature probe input). Two versions are available: DT5485P (supplied and controlled via USB) and Up to 85 V Power Supply Module for SiPM(USB controlled, with external +12V power supply). The unit can provide up to 10 mA and the output voltage could be regulated between 20V and 85V with a resolution of 1mV on a LEMO 00 connector. 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 DT5485P 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.
