sky observatory

ver. 3.0


ApplicationThe controller is designed to control speed of 12V DC motor with power up to 150W. The input system has been designed for both roll off roof and dome-based observatories. Built-in CW/CCW and Open/Close buttons allow manual control of the motors. The controller is also suitable for direct cooperation with ScopeDome USB cards. This allows you to control the motor by PC - eg. through ASCOM drivers.

Mainfeaturesa) Setting the engine speedb) Control the direction of rotation (CW/CCW)c) Adjustable soft startd) Adjustable soft stope) Built-in adjustable thermostat to control the temperature inside the driver's box f) Full protection of power transistors from overheating, short circuits and exceeding the maximum

motor currentg) Integrated inputs of limit switches stopping the engineh) Waterproof box
