Features

3730 Series Electro-Hydraulic Actuator The 3730 series electro-hydraulic actuator is powered by an AC380V three-phase alternating current source and operates on either a DC4-20mA analog control signal or an AC220V digital control signal. This product features a swing cylinder structure for its hydraulic transmission, making it more compact with greater output torque. Features and Characteristics of the 3730 Series Electro-Hydraulic Actuator.

1. The control module utilizes advanced hybrid integrated circuits, offering comprehensive functionality.

2. Non-intrusive remote operation: Parameters can be adjusted and set without opening the cover, allowing for manual operation on site.

3. Menu-based control module settings make parameter setting and function adjustment straightforward and convenient.

4. Input signal configuration: Choose between analog control (4-20mA) or digital control (220V) based on operational conditions, with independent wiring that does not interfere with each other; both can output a 4-20mA feedback signal.

5. Valve position display and functional indicator lights: Displays input signals and valve positions, with indicators for signal, manual/automatic, normal/reverse action, limit, and fault status.

6. Calibration function for input and feedback signals improves control precision.

7. Anti-interference feature: Set reverse action delay time to avoid reverse impact.

8. Zero point and stroke calibration are convenient and accurate, can be set at any position.

9. Four states for signal loss: Full close, full open, self-set (full stroke), hold position.

10. Electronic limit function: Provides feedback when in position.

11. Fault alarm function: A normally closed contact feedback will disconnect when the actuator's power supply fails; when set to adjust control, if the input signal is disconnected or there is a fault in the actuator, a pair of normally open feedback contacts will close. If a fault is detected, the motor power will be disconnected to protect the actuator.

12. Temperature protection function: When the temperature drops below -10°C, a heating device automatically activates to heat the oil block, ensuring the pump operates normally.

13. Advanced hydraulic system: Fully enclosed hydraulic power source with an integrated module structure, high efficiency, no leakage, pollution-free, resistant to vibration, long lifespan, and low maintenance costs.

14. Emergency manual function: Standard manual pump included for operation in case of power failure.

15. Action state memory function: Allows querying of cumulative action time and number of actions, providing a basis for optimization control and maintenance.
