Low voltage solutions

Low voltage for efficient and safe electrification

A low-voltage solution covers electrical systems from 0 to 120 VDC. It is a well-established technology in, for example, forklift trucks, work machines and indoor applications where silent operation, zero emissions and high personal safety are crucial.

Unlike high voltage, low voltage does not require any special electrical qualifications, which makes the systems easier to install, service and maintain. The technology also offers high flexibility and excellent energy efficiency, characteristics that make low voltage an attractive choice in many applications.

System design tailored to the user and reality

Designing a low-voltage system requires the same precision as designing a high-voltage system. Our task is to dimension the system precisely according to the application's needs, with the right power, the right operating time and the right user experience.

We are responsible for ensuring that every component works together in the system 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 deliver day after day.

Technology selection in the development of low-voltage solutions

Developing effective low-voltage solutions is about combining safety, simplicity and performance. At ETP, we build systems that are tailored to the specific needs of the application and the customer's goals. Through smart technology choices, optimisation and integration, we create 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 the analysis, we develop a concept sketch and begin the dimensioning process to select the right motor or combination of motors.

We work with three main technologies in low-voltage solutions: DC, AC and synchronous motors (SPM), selected based on how the application will be used. DC motors are used at low power levels where simplicity and price are most important. AC motors are used when high controllability is prioritised; from 3 kW and upwards, the price of an AC motor is the same as that of a DC motor. SPM technology is used when high efficiency and compact design are required. Regardless of the technology chosen, the combination of proven technology and modern control makes our systems a safe choice for everything from small mobile machines to marine auxiliary systems.

The energy density of the battery is the main challenge in an electrical system, and its properties require that all surrounding components be optimised with the battery in focus. By carefully analysing the energy and power requirements for each function, we dimension the system based on the right combination of energy efficiency, performance and cost. In many cases, several smaller motors provide higher overall efficiency and reduced energy requirements.

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