NEW product of the year 2019!

  • Support for external sensors (functionality will be available in new firmware)
  • Focuser mode
  • Small size and weight
  • improved compatibility with SynScan controller

The Telescope Control System (TCS) EQDrive Standard 4 automates the work of the mount (equatorial and azimuthal) or focuser. The TCS use Stepless(Vector) Algorithm and works with practically any mount operated by a stepper motor. It supports a wide range of Gear Ratio and Speed of axes, Soft acceleration and deceleration, allowing users to operate their telescope mount through Astronomical programs and SynScan hand controller.

  • Power supply: 10 – 28V 5A (recommended 24V)
  • Motor type: Bipolar stepper
  • Driver Voltage: Equal to Input Voltage.
  • Motor coil current: Adjustable 0.1 – 2.0A
  • Smooth acceleration and deceleration: Adjustable 0 – 10s.
  • Correction of nonlinearity of the motor: Yes
  • Axis gear ratio: Unlimited (Recommended 1: 1 – 1: 2000)
  • Case: Aluminum 100mm x 74mm x 29mm (L x W x H)
  • Weight: 190 grams
