SD series electric actuator is a standard product introduced by our company which is suitable for general occasions. It is mainly used for standard switch control and regulation control. This product has many unique features and functions.
Over torque protection: The actuator has an over-torque protection measuring mechanism, which can accurately measure the acting force of the valve. When the acting torque exceeds the range, the over-torque switch will act, and the control circuit will stop the operation of the direction and output the signal. When the motor stops, the valve and the actuator will be protected.
Motor overheat protection: There is a thermal relay inside the motor and the motor will automatically cut off the power supply when the motor is abnormally overheated.
Electrical protection: The input and output channels are all optically isolated.
