Multi‑stage Telescopic Electric Cylinder (Patented Product)
★ Customizable multi‑stage telescopic electric cylinders with stroke up to 20 meters and load capacity up to 20 tons.
The multi‑stage telescopic electric cylinder is driven by a servo motor to rotate multiple ball screws, driving the screw pairs mounted on the pistons of multi‑section telescopic rods to achieve reciprocating linear motion.Compared with single‑stage servo electric cylinders, it features a simpler structure and excellent servo control performance, making it widely used in various industries.
In actual production and manufacturing applications, there are often requirements such as limited installation space, long working stroke, or variable stroke during operation.Single‑stage electric cylinders can meet the requirement of small installation space, but cannot achieve long working stroke.
Multi‑stage telescopic electric cylinders are characterized by small installation space, long stroke, stable operation, high precision and controllability.
Our multi‑stage telescopic electric cylinders all adopt ball screws (higher transmission efficiency and higher precision than trapezoidal screws) as the transmission components.They can be designed with 3, 4, 5 or 6 telescopic sections including the main body.
They are widely applied in robots, automatic photography systems, transportation, inspection equipment, AGV logistics vehicles, automated equipment and other fields.
FAQs
Example: 800W PV array + 48V battery bank → 800 ÷ 48 × 1.25 = 20.8A → Choose a 20A or 30A controller.
Also, ensure the PV open-circuit voltage (Voc) does not exceed the controller's maximum PV input rating.
Connect the Battery first (positive to positive, negative to negative).
Connect the Solar Panels (PV input).
Connect the Load (optional).
Note: Use appropriately sized cables and fuses for safety.
PV Voltage Too Low: Ensure the solar panel voltage is at least 5V higher than the battery voltage.
Wiring Issues: Check for reversed polarity, loose connections, or blown fuses.
Battery Full: The controller will taper or stop charging once the battery is full.
Over-temperature Protection: The controller may reduce current if it gets too hot.
A built-in sensor adjusts the charging voltage based on battery temperature. It prevents overcharging in hot weather and undercharging in cold weather, significantly extending battery life.
MPPT (Maximum Power Point Tracking) is an advanced technology that continuously monitors the voltage and current output from solar panels, dynamically adjusting the operating point to extract the maximum available power under varying light conditions. It efficiently converts high PV voltage to the battery’s charging voltage, significantly boosting energy harvest compared to traditional PWM controllers.
