Overview
The A7590D is a high-voltage isolated regulator specifically designed for SiPM bias, with both positive and negative output polarity. The module’s output is electrically isolated from its power supply and control interface, allowing it to be used as a floating power supply. Alternatively, by grounding either the negative or positive output, it can function as a non-isolated positive or negative power supply. It features a built-in temperature compensation controller with a programmable coefficient.
The module can be digitally controlled via UART and I²C. The output voltage can also be controlled proportionally to an analog input.
The A7590D can provide up to 50 mA, and the output voltage can be regulated between 2 V and 75 V with a resolution of approximately 1 mV.
The units are supplied as PCB-mount modules (2.54 mm pin pitch).
The DT5490 is a desktop version of the unit, with Ethernet and USB control, and an external +12 V power supply. A desktop +12 V power supply, Ethernet cable, USB cable, and TMP37 temperature probe are included in the kit. The DT5490 can be controlled via the ZEUS 2 software, a web interface, or the front panel display.
The ZEUS 2 control software is provided free of charge; it allows monitoring and control of multiple modules simultaneously and is compatible with Windows, Linux, and macOS
Developed in collaboration with Nuclear Instruments.
