When engineers search for a 24V DC linear actuator, they are usually solving a specific problem: how to move heavy structures—solar panels, heliostats, or industrial equipment—accurately, repeatedly, and without failure in harsh outdoor conditions. Dongguan TOMUU Transmission Technology Co., Ltd., operating under the TOMUU brand since 2015, has built its entire product strategy around answering that exact question for the photovoltaic and industrial automation sectors.

What a 24V DC Linear Actuator Needs to Deliver

A reliable 24V DC linear actuator must balance several competing demands: enough dynamic load capacity to move a tracker row under wind and operational stress, enough static load capacity to hold position safely when stationary, resistance to dust and water ingress, and the ability to function across extreme ambient temperature ranges. TOMUU's product documentation addresses each of these requirements directly, with every actuator in its 24VDC lineup specifying exact load ratings, IP protection class, and temperature tolerance rather than vague marketing claims.

TOMUU's 24V DC Linear Actuator Lineup

Single and Multi Electric Drive Actuators

TOMUU's single and multi electric drive series—U10G, U20, U20F, and U10S—all run on a 24VDC input voltage, making them compatible with standard solar tracker DC supply systems. These models share a common operating profile: a no-load speed of 1.44 mm/s, a full-load speed of 1.4 mm/s, a stroke range of 300–1000 mm, IP66 dust and water protection, side force tolerance of 2000 N, and an ambient temperature range of -40°C to +65°C.

Within this family, load capacity scales to match different tracker designs. The U10G delivers a dynamic load of 31,000 N and a static load of 80,000 N. The U20 matches the same 31,000 N dynamic and 80,000 N static figures, while the U20F offers a 24,000 N dynamic load at the same 80,000 N static rating. For installations requiring even greater holding force, the U10S steps up to a 34,000 N dynamic load and a 110,000 N static load, the highest static capacity in this sub-group.

For lighter-duty or space-constrained applications, the U7 offers a more compact profile: a 2,000 N dynamic load, a 30–400 mm stroke, IP65 protection, and a faster 5.4 mm/s no-load speed with a retracted length of S+105 mm, suited to installations where speed and a smaller footprint matter more than maximum force.

Mechanical Linkage Actuators

TOMUU also produces a dedicated mechanical linkage series designed to coordinate motion across multiple actuation points in linked tracker architectures. The U17A-主 and U17A-副 (main and secondary units) each run on 24VDC and deliver a 20,000 N dynamic load with a 70,000 N static load, while the U17B-主 and U17B-副 pair matches the 20,000 N dynamic rating but raises static holding to 130,000 N. All four units operate at a 0.75 mm/s no-load speed and a 0.5 mm/s full-load speed, with IP66 protection and the same -40°C to +65°C operating window, enabling synchronized, slow, and precise movement across linked tracker rows.

Proven Performance Across Global Projects

TOMUU's actuators are not confined to laboratory specifications—they have been deployed across more than 38GW of installed solar tracker capacity worldwide, with service coverage spanning more than 20 countries and regions. Specific project cases documented by the company illustrate this range: mechanical linkage actuators were used in a 100 MW utility-scale tracking plant in Weinan, Shaanxi, China, and in another 100 MW project in Jiangxi, China. Multi electric linear actuators supported a 293 MW tracking project in Shihezi, Xinjiang, China. Single electric linear actuators were deployed in a 100 MW project in the United States, a 394 MW project in India, and a 100 MW project in Canada. Fixed adjustable linear actuators were applied to a 100 MW project in Dunhuang, China, and a 180 MW project in the Longyuan project in China.

This geographic and application diversity—spanning North America, South Asia, and multiple Chinese provinces—demonstrates that TOMUU's 24VDC actuator technology is engineered for consistent performance across widely different climate conditions and project scales. The company has also been recognized as a high-quality supplier of domestic PV head enterprises and counts Trina Solar among its business partners.

Quality Assurance and Certifications

Behind every 24V DC actuator TOMUU produces is a quality management system backed by ISO9001, ISO14001, and ISO45001 certifications. Product safety is further validated through UL, CE, KCC, and 3C certifications, along with IP protection certification. Patent protection includes a US patent for a high-efficiency large capacity solar electric actuator, along with appearance patent and design patent registrations, reflecting sustained investment in proprietary engineering rather than off-the-shelf design.

TOMUU has also undergone rigorous environmental testing, including damper salt spray testing of 800 hours, and its actuators carry IP66 and IP68 protection ratings depending on the product line, allowing continued operation in environments with heavy dust, rain, or coastal salt exposure. The company's recognition as a National High-Tech Enterprise and a Guangdong Province Specialized and New "Little Giant" Enterprise further reflects its standing within China's technology manufacturing sector.

Why TOMUU's 24V DC Actuators Fit Real-World Tracker Needs

For buyers evaluating a 24V DC linear actuator, the core decision points are consistent: load capacity under both dynamic and static conditions, environmental sealing, temperature tolerance, and a documented track record across real installations. TOMUU addresses each of these through a structured product line—single/multi electric drive units for standard tracker configurations, mechanical linkage units for synchronized multi-point systems, and complementary fixed adjustable and damper products for specialized tracking needs.

With an in-house R&D, production, and sales structure, five subsidiaries located in Dongguan, Xiamen, Vietnam, and other locations, and a 2023 annual output of nearly RMB 400 million, TOMUU presents a documented manufacturing capability behind its 24VDC actuator catalog. For engineers and procurement teams comparing options in this category, the combination of specified technical parameters, verified certifications, and disclosed project deployment data gives a clear basis for evaluating fit against project-specific load, environmental, and climate requirements.
