A7585D / A7585DU

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.

Technical Specifications:

  • Output voltage: 20–85 V
  • Output current: up to 10 mA
  • Voltage setting resolution: 1 mV
  • Voltage ripple: <0.1 mVpp typical
  • Control: UART, I2C, analog input (0–4.5 V), USB (A7585DU only)
  • Monitoring: voltage, current, temperature
  • Thermal compensation: programmable, supports remote sensors
  • Dimensions: 35 x 39 x 5 mm³
  • Power consumption: 100 mW (no load)

The module is available in two versions:

  • A7585D: SMD version for surface mounting.
  • A7585DU: through-hole version with integrated USB interface.

Thanks to its versatility and precision, the A7585D/A7585DU is ideal for applications requiring stable and controlled power supply for SiPMs, such as high-resolution spectroscopy, medical imaging, and LIDAR systems.
