24V DC U15A Linear Actuator 3300N-4700N Push Pull for CSP Tower System
U15A for CSP Tower Heliostat Structure, Speed & Installation Selection
The TOMUU U15A is a 24V DC linear actuator designed for CSP tower heliostat structures requiring controlled linear movement, project-specific stroke and installation geometry.
With a rated push and pull load range of 3,300–4,700N, a speed range of 1.17–3.34mm/s and a minimum installation dimension based on Stroke + 275mm ±5mm, the U15A can be selected according to heliostat structure, mounting space, adjustment range and feedback requirements.

3,300–4,700N Push & Pull Load for CSP Tracking
The U15A rated operating load is 3,300–4,700N in both push and pull directions. This is the primary working load range used when evaluating the actuator for heliostat positioning.
The actuator also has a maximum static load of 15,000N, which refers to static loading conditions and should not be interpreted as the rated operating load.
Load Definition:
Rated Push & Pull Load: 3,300–4,700N
Maximum Static Load: 15,000N
Load & Speed Selection
Load and speed should be evaluated together when selecting an actuator for a CSP heliostat structure. The required configuration depends on the mechanical geometry, stroke and positioning requirements of the project.
| Voltage | Push Load | Pull Load | Speed Range |
| 24V DC | 3,300–4,700N | 3,300–4,700N | 1.17–3.34mm/s |
Final load and speed configuration should be confirmed according to the heliostat structure and project requirements.
Hall Signal Feedback for Position Monitoring
Hall signal feedback is provided as the standard feedback configuration for the U15A, supporting actuator movement monitoring during CSP heliostat adjustment.
Feedback requirements should be evaluated together with the control system, stroke and required positioning logic of the project.
U15A Installation for CSP Heliostat Structures
The U15A minimum installation dimension is based on Stroke + 275mm ±5mm. The standard front mounting configuration uses a Ø14mm hole, with a standard Ø14mm mounting axis.
Stroke and installation dimensions should be selected according to available mounting space, heliostat geometry and the required adjustment range.
Selection Factors:
Load · Speed · Stroke · Installation Geometry · Feedback · Adjustment Range
