Products
1. Ultrasonic Dogvane & Anemometer
There is no mechanical moving parts, which with high accuracy and long lifespan. It can remove snow and frost automatically because of the electrical heating function. It can be used in cold and bad condition areas. All HUMMER pitch-controlled systems match with the ultrasonic dogvane & anemometer.
2. PLC control system
Hummer 5kw and larger models are matched with Siemens PLC system, which is with high disturbance resisting and stable operation. Hummer pitch-controlled system adopts double PLC systems, the two systems are on real-time communication, which means that, if any of the PLC system is broken down, the other one can stop the system safely, which can greatly protect the system.
3. Siemens servo motors
Hummer pitch-controlled models matches with three high-performance Siemens server motors:
(1) Yawing servo motor (2) Hydraulic braking servo motor (3) Pitch servo motor Siemens PLC system greatly matches with Siemens servo motors, which make Hummer pitch-controlled models operate reliably. Because of the PID Self-turning functions of the Siemens servo motors, the blades works rapidly and reliably.
4. Touch screen
Hummer 5kw and larger models match with touch screen. There is internet access, which can remote monitoring the system and get the operation data. Especially when there is fault, users can contact Hummer technician, they can remote diagnosis and debug the fault, and can offer software updating function.
