AstroLink 4 USB

790.00  incl. Vat


AstroLink is now available with an integrated USB3.0 hub. The digital part power supply is galvanically isolated from the analog, and the data stream is opto-isolated as well. Out-of-the-box focuser unipolar, bipolar, and microstepping control, regulated PWM outputs, switchable DC outputs, 5V regulated output,  overcurrent and overvoltage protection, temperature/humidity/sky temperature sensors – all in one box. Advanced panel software with ASCOM multidriver support to control all functions. INDI driver is available.

Please add 2-3 days to the lead time due to new enclosures manufacturing and the device final tests.

In the box:

  • AstroLink 4 USB device (black, graphite, or red)
  • XT60 female socket for custom power supply adaptation

Dedicated power supplies or cables can be purchased separately in recommended accessories.

Mounting plates and brackets can be found here.

And here are the key features of AstroLink 4 USB:

  • focuser motor control for Robofocus, Moonlite, or generic unipolar or bipolar stepper motor
  • 1/8 and 1/32 microstepping control with 1.5A maximum current
  • advanced temperature compensation with scripting support and compensation calculator
  • permanent focuser position – no need to park focuser after the session
  • 2 adjustable PWM power outputs to control dew heaters, telescope fans, or custom Peltier coolers. The maximum load is 40W per output
  • 3 switchable power outputs to power mount, cameras, or filter wheels. The maximum load is 5A per output
  • 1 additional permanent power output
  • 1 additional regulated 5V output (maximum load for connected USB devices and additional 5V output cannot exceed 3A). This output voltage is galvanically isolated from the input voltage.
  • XT60 high current input voltage socket
  • temperature/humidity/sky temperature/pressure sensors to monitor environmental conditions and calculate the dew point. It is also used to automatic control od dew heaters
  • monitor voltage, current consumption, and total energy consumed during the session – useful when working in the field with a battery
  • user-defined alerts for voltages, current, energy, and temperature changes conditions
  • programmable overcurrent and overvoltage protection
  • integrated USB 3.0 hub with galvanically isolated power supply (three outputs available)
  • opto-isolated USB 3.0 input
