SA Intelligent non-invasive electric actuatorDetailed product description：

The SA intelligent non-invasive electric actuator is a new generation of intelligent, digital, fully Chinese menu display, and remote control electric actuator developed using ultra large scale digital integrated circuits based on the introduction of foreign intelligent electric actuator technology. The non-invasive design adopts a magnetic induction control knob and does not have a through shaft passing through the control box; Non contact debugging: using an infrared remote control to set the operation of the electric device, truly eliminating the need to open the cover for debugging; Double sealed structure: When the junction box is opened during installation and debugging, the interior of the electric device still receives good sealing protection. The waterproof design enables the electric device to operate normally within 48 hours of being submerged in water;
Torque protection: The protection torque can be set arbitrarily within the range of 40% to 120% of the rated torque, and the protection values for the opening and closing directions can be different to protect the valve and the electric device itself;

Valve position limit protection: When this function is allowed, the electric device will automatically stop running when it reaches the set valve position limit;
Power phase loss protection: Real time detection of power phase loss in dynamic situations during operation to prevent motor phase loss operation;
Electronic latch protection: Within 5 seconds of the start signal, the torque protection function is automatically disabled to obtain maximum output torque and open the stuck valve. If the valve cannot be operated during this period, the motor power will be automatically cut off and an alarm will be triggered to protect the motor of the electric device;
Motor overheat protection: There are two thermal relays inside the motor coil, which automatically cut off the motor power supply when the motor overheats;
Electrical protection: Both input and output channels adopt photoelectric isolation;
Valve position and torque detection: Hall effect magnetic pulse signals are used to detect valve position, and the current and magnetic flux of the motor are used to continuously measure torque. Completely eliminate mechanical wear, stable and reliable;
Automatic phase sequence adjustment: Automatically detect the phase sequence of the three-phase power supply connected, and adjust the phase sequence automatically through logical operation, without the need for users to consider the phase sequence of the three-phase power supply connected;

The infrared remote control of SA intelligent non-invasive electric actuator can be set with the following contents:
Direction of rotation of output shaft when closed
Disable the limit protection selection
Torque setting values for opening and closing operations
Confirmation of the positioning of the closed and open limit positions
ESD selection
Valve position digital display: During the opening or closing process of the electric device, the valve position changes are displayed in real-time on the LCD screen in numerical percentage form.
Power off data storage: After the main power supply loses power, the detection circuit is powered by the battery and supports valve position detection during handwheel operation. When there is no battery, the current valve position can still be effectively saved even when the main power supply loses power;
Handwheel operation: The driving handwheel can provide reliable emergency manual operation in case of power failure. Due to the design prioritizing electric operation, it automatically switches to electric operation mode when powered on (except when intentionally locked in manual operation);
Explosion proof structure: designed according to GB3836 standard, with sufficient length of explosion-proof joint surface and good sealing performance. At the wire inlet, there are threads for installing explosion-proof pipes;
Low inertia high torque motor: Adopting a low inertia high torque motor, it quickly reaches its peak value when starting. Extremely small out of limit motion when not excited;
Good lubrication conditions: Both the worm gear and bevel gear pairs work in an oil bath, with good lubrication conditions, minimal wear, and long service life;
Solid state circuit detection: edible solid-state circuit detection torque, avoiding the use of spring switches and levers for torque detection, reliable performance;
