Overview
The DT5490 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 DT5490 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 DT5490 features Ethernet and USB interfaces, and requires 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.
