Control box for all AlfaSpids AZ rotators which does
not have the H/R (high resolution) indication. It is only the BIG
rotators which are supported to be used with 24V voltage, all others are max
Please consider that the engine in the
rotator can draw quite a lot of current in the startup, peaks up to 10A. So
please think about that when choosing power supply and thickness of the
cabling. Connections 1 and 2 (and 5 and 6 if rotator has elevation) is the feed
to the motor. If voltage drops too much because of poor cabling or power supply
you could lose pulses and then the indication is not accurate, even though it
is easy to recalibrate it is unnecessary.
This controller is also used or the EL
rotator, which only has elevation.
Shipment includes CDROM with software,
mouse for (optional) control and USB cable to connect to PC.
Recommended software to use: PSTrotator by
YO3DMU. Besides this software, most software on the market for rotator control
supports the AlfaSpid rotators.
The control box can also emulate Yaesu,
Orion and HyGain. Which expands the possibilities for computer control even
If you want more configuration options,
like soft start/stop or use AlfaSpids H/R rotators you will have to choose the
MD01 (rack mounted) or MD02 controller.
