Smart control

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 1mV. Moreover, the ZEUS control software is provided for free; ZEUS allows to monitor and control multiple modules at same time.

Applications

SiPM (single and matrix) bias
PIN diodes bias
SiPM characterization
High resolution spectroscopy systems
Medical Imaging systems
LIDARs

Plug and Play

The A7585DU model comes with Micro-USB Connection for an easy plug ‘n play functionality providing power and data transfer in one cable. Simple to setup and control, just install the software ZEUS.

The module also has a 2.54 mm connector to integrate it in the user circuit and operate in self-power mode.
