24V DC Configuration for Solar Thermal Tracking
The U15A uses a 24V DC power configuration and is designed for controlled linear movement in heliostat positioning mechanisms.
Actuator selection should be based on the required load, stroke, installation geometry, adjustment range and control requirements of the solar thermal tracking structure.
Application Focus:
24V DC linear positioning for heliostat angle adjustment and solar thermal tracking structures.
Hall Signal Feedback for Position Monitoring
Hall signal feedback is provided as the standard feedback configuration for the U15A, allowing actuator movement to be monitored during heliostat positioning.
Feedback requirements should be confirmed together with the control system and required positioning logic of the project.
Load & Speed Configuration
| Voltage | Push Load | Pull Load | Speed | Max. Static Load |
| 24V DC | 3,300–4,700N | 3,300–4,700N | 1.17–3.34mm/s | 15,000N |
Stroke & Installation Selection
The U15A minimum installation dimension is based on Stroke + 275mm ±5mm. The standard front mounting configuration uses a Ø14mm hole.
Stroke and installation dimensions should be selected according to the available mounting space, heliostat geometry and required adjustment range.
Selection Factors:
Load · Stroke · Installation Geometry · Adjustment Range · Feedback · Project Quantity
TOMUU Experience in Solar Thermal Projects
TOMUU actuator solutions have been applied in solar thermal tracking projects requiring mechanical positioning and controlled movement of heliostat structures.
Representative CSP Project — Tibet, China
TOMUU supplied actuator solutions for the tower CSP heliostat tracking project in Anduo, Tibet, located at approximately 4,650 meters above sea level.
The project shown here uses TOMUU U23D actuators. These images demonstrate TOMUU experience in solar thermal tracking applications and are not presented as a U15A installation.
Manufacturing & Engineering
TOMUU combines actuator manufacturing, application engineering and product testing to support solar thermal and heliostat tracking applications.
