Description
The DT5490 is a desktop, single-channel high-voltage regulator specifically designed for biasing Silicon Photomultipliers (SiPM). It delivers a digitally-controlled adjustable output between 20 V and 85 V with a maximum current of 10 mA and a 1 mV setting resolution, through a LEMO 00 output connector.
It integrates a built-in temperature-compensation controller with programmable coefficient, with a temperature probe connected through a 3.5 mm audio socket, and is fully managed over USB and Ethernet — making it a compact, stand-alone bench solution for stable SiPM biasing. The free ZEUS software allows control and monitoring of multiple modules from a single graphical interface.
The DT5490 is the desktop, USB-controlled counterpart of the PCB-mount A7585D SiPM power-supply module, offering the same 85 V / 10 mA biasing performance and ZEUS software in a ready-to-use bench enclosure.
