Description
The A7585D/A7585DU is a high-voltage power supply module specifically designed for biasing Silicon Photomultipliers (SiPM). It provides an adjustable output between 20 V and 85 V with a maximum current of 10 mA, ensuring extremely low ripple (<0.1 mVpp typical) and a voltage setting resolution of 1 mV.
Key Features:
- Digital and analog control: supports UART, I2C, and an analog input (0–4.5 V) for output voltage adjustment.
- Automatic thermal compensation: integrates a temperature compensation controller with programmable coefficient, also supporting remote temperature sensors.
- Real-time monitoring: allows high-resolution real-time reading of voltage, current, and temperature.
- USB interface (A7585DU only): the DU model includes a USB-UART bridge, enabling power and communication through a single USB cable.
- ZEUS software: provided for free, it enables control and monitoring of multiple modules simultaneously via an intuitive graphical interface.
- Compact size: 35 x 39 x 5 mm³, ideal for integration in space-constrained environments.
