Specification:Color: Silver Material: Aluminum AlloyInput Voltage: DC 12VRated Current: 3AmpStroke length = 250mm(10")Retracted length = 370mm(14.8");Extended Length= 620mm(24.8")Rated Load: 900NTravel Speed: 10mm/sLimit Switch: Built-inWorking Temperature: -20ºC to 65ºCProtection Class: IP54Duty Circle: 25%Noise Level: <50dBHow To Install1. Prepare to connect the two wires of the actuator to a 12 volt battery2.Blue wire to the positive terminal and grey wire to negative terminal will make the actuator extend. To make it retract, just reverse the terminal connections.3.To simplify the last step, you can prepare a reverse polarity relay or switch (not included) for the actuator. When you want the actuator to extend and retract, just press the switch4. Your actuator will hold its position when the power is off. It will automatically stop when reaches the end.5.The actuator has pre-installed inner limit switch, it cannot be adjustable.6. It comes with mounting brackets.How to protect your actuator:1. Please use the 12V DC power adapter2. Please do not exceed the rated load3. All the actuators have duty cycle, they are unable to work all the time without stop. The duty cycle of this actuator is 20%. it means that your actuator needs 4 minutes to rest for every 1 minute of work. If the actuator keeps working for long time, the motor is easily burnt out.4. Please be careful, the actuator not completely waterproofWidly Use:Furniture and home applicationHospitals and healthcareIndustrial and construction applicationAgricultural machineryPackage Included: 1 X 10" Linear Actuator 2 X Mounting Bracket 1 X Screw Set
