Alpha SPID RAS
Heavy Duty Rotator
The RAS is an excellent option for medium sized EME arrays with good reliability and easy setup and interfacing to PC systems. Recommended for LFA and OWL arrays up to 14el x 4.
Angle of turn azimuth: 360 + / - 180 degree Angle of turn elevation: 180 + / - 20 degree Rotational speed azimuth: 120 sec. (12V), 60 sec. (18V) Rotational speed elevation: 80 sec. (12V), 40 sec. (18V) Supply: 12V-18V DC Weight: 14 kg Input signal: pulses (one pulse per degree)
All SPID rotators require an external power supply.
Typically they are run from the station 13.8v supply. For the larger rotators with sizable antennas, upto 8 amp would be required. In many cases a separate PSU from the rig is recommended, and start surge should be factored in.
