Slewing Controller is a kind of Tower Crane slewing control device, combined speed and voltage regulation and eddy current speed controling. The slewing control block control the speed of eddy current torque motor, to make the tower crane slewing mechanism start, working and stop smoothly. This kind of Slewing Controller is used to regulate and control the speed of three-phase torque motor of AC 50Hz, voltage 380V.
HRCV slewing controller is a hoisting slewing controller developed by our company according to service condition of customer.
The main technical feature as follows:
(1) This product combined the controller and thyristor module,the connection of the users is simple and easy.Prevent the damage of the controller and thyristor module caused by mis-wiring of the customer.
(2) Realize the best optimization of AC voltage control curve and DC voltage control curve.
(3) With the function of inching during operation, realize the accuracy.
(4) The electronic components adopt the imported industrial grade chip, on the control panel directly with power supply and direction indicator light.
(5) Adopt the coating treatment on the printed circuit board,enhance the dust prevention and anti-condensation capacity of the circuit board.
