Rotator BIG RAK

It is based on the worm gear, worm and worm wheel made of steel. These features ensure long life and durability of the device. Its advantage is the possibility to adjust the worm and worm wheel clamping, clearing backlash in the drive mechanism, which may be necessary in the case of wear and tear after long-term use. Feedback to controller is not via potentiometer, but digitally via reed contact with accuracy of 1°. The device surface is covered with powder coating, effectively protecting against corrosion. Range trading is protected by limit switches. The rotors have no built-in power supply but are supplied with DC voltage 12-24V, ideal for portable operation or field days. The torque of the rotors is with about 900 Nm, much higher than other rotors in this price class.
