Load & Speed Configurations
U20A provides two rated speed configurations while maintaining the same 31,000N push and pull load.
| Code | Voltage | Push Load | Pull Load | Rated Speed | Rated Current |
| A | 24V DC | 31,000N | 31,000N | 0.55mm/s | 5A |
| B | 24V DC | 31,000N | 31,000N | 1.1mm/s | 7.5A |
Dimensions & Installation
The standard minimum installation dimension is Stroke + 320mm ±5mm.
For stroke lengths above 500mm, the overlap distance and initial installation dimension may need to be increased according to the actuator configuration.
Designed for Solar Tracking Systems
U20A was developed specifically for solar tracking applications where high load capability and stable low-speed movement are required.
The 31,000N push and pull capacity provides a strong drive option for tracker structures, while the two rated speed configurations allow the actuator to be selected according to different project and structural requirements.
With a 24V DC power supply, 10% duty cycle and operating temperature range from -40°C to +65°C, U20A is designed for long-term outdoor solar tracker operation.
