The gearbox is filled with aviation-grade wide-temperature grease, which does not solidify at low temperature of -40°C and does not run off at high temperature of +80°C. The Bit-cctv seal lubrication system ensures that the equipment does not need to be filled with lubricating oil frequently during the entire life cycle, which greatly reduces the maintenance cost of high-altitude work.
Using high-strength copper alloy worm gear and hardened steel worm, Bit-cctv unique self-locking structure design can withstand up to 2000 Nm braking torque, completely eliminate the “windmill effect” (Windmilling) in high wind environment, to ensure that the antenna pointing in the hurricane is still motionless.
Built-in 16-bit absolute encoder, with closed-loop control algorithm, will repeat the positioning accuracy control within 0.05 °. Compared with the traditional potentiometer feedback system, the Bit-cctv scheme can significantly improve the tracking gain of Ka/Ku band narrow beam satellite signal and reduce the link los
The fuselage is made of die-cast aluminum alloy and 3 heavy-duty anti-corrosion coating on the surface, combined with special fluorine-containing rubber sealing ring, through 96 hours of salt spray test. Even in extreme environments such as high salt fog at sea or desert dust storms, the internal precision gears and circuits are protected from corrosion and have a service life of more than 5 years.
Support soft start and soft stop function, automatically adjust the acceleration and deceleration curve according to the load inertia. This 1 the design effectively avoid the mechanical impact of emergency stop on the antenna array and the installation tower, protect the precision microwave components, and reduce the risk of overheating of the motor.
Native support for Pelco-D/P and other mainstream control protocols, can be directly connected to the existing security or communication network via RS-485 or Ethernet. System integrators can achieve remote control without additional development drivers, significantly shortening the project deployment cycle.
