Low-voltage solutions

Low voltage for efficient and safe electrification

Low-voltage solutions cover electrical systems up to 120 VDC. This technology is well established in applications such as forklift trucks, work machines and indoor applications, where silent operation, zero emissions and high levels of personal safety are essential.

Unlike high-voltage systems, low voltage does not require special electrical qualifications, making installation, service and maintenance simpler. The technology also offers high flexibility and excellent energy efficiency, making low-voltage solutions an attractive choice for a wide range of applications.

System design optimised for real-world operations and the end user

Designing a low-voltage system requires the same level of precision as a high-voltage system. Our role is to dimension each system precisely to the application’s requirements – delivering the right power, the right operating time and the right user experience.

We ensure that every component works seamlessly together and that the solution delivers reliable performance over time. The result is a system that is safe to own, easy to maintain and built to perform day after day.

Engineering low-voltage systems for safety, efficiency and performance

Developing effective low-voltage solutions is about balancing safety, simplicity and performance. At ETP, we design systems tailored to the specific requirements of each application and the customer’s objectives. Through smart technology choices, optimisation and integration, we deliver solutions that are energy-efficient, cost-effective and easy to implement.

Each system begins with a thorough analysis of the machine’s power and energy requirements. Based on this analysis, we develop a concept design and initiate the dimensioning process to select the most suitable motor or combination of motors.

We work with three main technologies in low-voltage systems: DC, AC and synchronous permanent magnet (SPM) motors, selected according to how the application will be used. DC motors are typically used at lower power levels, where simplicity and cost are the main priorities. AC motors are chosen when high controllability is required, from around 3 kW and upwards, the cost of AC and DC motors is generally comparable. SPM technology is used when high efficiency and a compact design are essential. Regardless of the technology selected, the combination of proven components and modern control systems makes our solutions a safe and reliable choice for everything from small mobile machines to marine systems.

Battery energy density is one of the key challenges in electric systems, and its characteristics require all surrounding components to be optimised with the battery in focus. By carefully analysing the energy and power requirements of each function, we dimension the system to achieve the optimal balance between energy efficiency, performance and cost. In many cases, using several smaller motors results in higher overall efficiency and reduced energy demand.

Our low-voltage solutions are based on lithium-ion batteries offering long service life, high safety and customised control. The result is flexible, reliable systems that combine high technical performance with straightforward integration into the customer’s application.
