GREENLINE ROOF DRIVE WITH ASCOM

The ASCOM Automatic Roof Drive kit for Greenline roll-off observatories is a simple plug and play solution and is compatible with Mini, Medium and Big sized observatories. Being fully ASCOM-compatible allows complete automation over ethernet.

All Greenline observatories have pre-installed cogrim gears, pulleys and counterweights, so installing the roof drive system is as simple as inserting the motor unit.

Features

• Electric motor with industry-grade gearbox
• 12V motor
  
• Rack & pinion linear gear system
• Pre-wired, ready to use system, plug & play
• Industrial grade open & close limit switches
• Two-button control box with key mains power switch 
• Includes all fixing materials, motor (disengageable) bracket and watertight box for all electronics

The best solution to power the motors of Greenline observatories is a 12V DC battery using thick cabling (we suggest 6 AWG) and Anderson Powerpole connectors capable of up to 50A. Alternatively, industrial-grade 12V DC switchmode power supplies will also work.

You can use up to 15V DC (for example lithium batteries) but once you drop too much below 12V, torque drops off dramatically.

RC-33M belt drive draws 40.8A (only ONE motor can run at the same time with one shutter engaged)

Roll-Off observatories roof drives draw 18.5A when opening and 14A when closing.

Both control units are polarity protected - the units do not work when plus and minus are swapped.
