Specifications:
Optional working voltage: DC 12V or DC 24V. Unless you only have 12V power supply available, we recommend you choose the linear actuator with 24V working voltage.
Stroke range: 0.4 ~ 79 inches or 10 ~ 2000 mm

| 25mm/s | 1000N / 100 kg / 220 lbs |
| 32mm/s | 800N / 80 kg / 180 lbs |
| 50mm/s | 600N / 60 kg / 130 lbs |
| 100mm/s | 300N / 30 kg / 60 lbs |
Note:
1. The above data is the maximum load capacity that can be obtained when the linear actuator runs in the vertical direction. If the weight of your equipment (such as a cellar door) is 100kg, and you want to use a linear actuator to open this door, you need to calculate the actual force acting on the linear actuator according to your installation method. This force is usually 2-5 times the weight of the cellar door. If you don't know how to calculate it, please contact us for help.
2. The above is the speed at no load, and the actual working speed will gradually slow down as the load increases. Full load speed is approximately 60-70% of No-load speed.
3. Different speeds correspond to different maximum loads. Please select the right speed according to the speed and maximum load you need.
4. Linear actuators are not recommended for continuous operation under maximum load, we recommend letting it work at about half of the maximum load to get a longer working life.
5. For linear actuators with a stroke greater than 500MM, you should not normally allow them to operate at their maximum stroke under heavy loads. If the actual stroke you want is 600MM, we recommend that you choose a linear actuator with a stroke of 700-800MM.
6. The maximum pull force of the linear actuator is slightly less than its maximum thrust force.
The information for synchronous controller:
Introduction:
If you want to use multiple linear actuators to raise and lower an equipment, for example two or four electric actuators. Since the high speed DC motors in electric actuators cannot run at exactly the same speed, so the movement speed of the electric actuator will also be different. When multiple electric actuators work at the same time, their actual speeds cannot be exactly the same. In this case, we can use a synchronous controller to operate multiple linear actuators to rise or fall synchronously. They work completely in sync without any difference.
Working principle:
If you want to use a synchronous controller to operate 2 or 4 linear actuators fully synchronously, you will need to add built-in Hall effect sensors to each linear actuator. And when you purchased Hall effect sensor along with linear actuator, we will install Hall effect sensor to linear actuator for you.
When 2 or 4 linear actuators are running together, Hall sensor will send Hall signals to the synchronization controller, and the controller will adjust the running speed of each linear actuator, so that all linear actuators run at the exact same speed.
Feature:
It can operate two electric linear actuators B to run completely synchronously.
Wired control via a control handle.
Wireless control via a remote.
Three function buttons: Up, Down and Stop.
With reset button.

Operating Temperature: -20°C ~ +70°C
Case size: 145 x 90 x 40 mm (5.7 x 3.6 x 1.6 inches)
Connection:
1) Connect the positive pole of DC power supply to terminal <+> of the controller, and connect the negative pole of DC power supply to terminal <–> of the controller.
2) Plug two linear actuators to the controller.
3) Plug the control handle to the controller.
Operation via the control handle:
1) Press the UP button of the control handle, two linear actuators extend outward at the same time, they will reach the maximum stroke at the same time and stop automatically.
2) Press the DOWN button of the control handle, two linear actuators retract inward at the same time, they will fully retract at the same time and stop automatically.
3) During operation, you can also press the STOP button to stop two linear actuators at the same time.
Operation via the remote control:
1) Press the button ▲ of the remote control, two linear actuators extend out at the same time, they will reach the maximum stroke at the same time and stop automatically.
2) Press the button ▼ of the remote control, two linear actuators retract inward at the same time, they will fully retract at the same time and stop automatically.
3) During operation, you can also press the STOP button to stop two linear actuators at the same time.
Reset Function:
When this system has been running for a long time, or after frequent momentary operation of two linear actuators, they may no longer be fully synchronized. At this time, the controller's indicator light will flash green, and the controller will stop working, then you need to use the reset button to reset the controller.
Operation: Press and hold the reset button for more than 5 seconds, then the controller will reset.
Note:
1. Each linear actuator would require two mounting brackets, one to fix the head of linear actuator and another to fix the bottom of linear actuator. This kit does not contain fixed mounting brackets, please buy them from the drop down menu.
2. You need to use a DC12V/20A or DC24V/10A switching power supply to power this kit. This kit does not contain this power supply, please buy it from the drop down menu.
