„Made in Germany“ remains an important and highly sought-after quality standard for machine and drive technology within the international market. This is why our transformers, chokes and sinusoidal
filters play a crucial role for our customers in drive technology. They ensure trouble-free system operation and prolong the service life of the motors. Our bespoke developments and the harmonious interaction of the components ensure optimised operation, always in line with our customers‘ specific requirements.

ELTRA mains starter devices are characterized by their robust design for high currents during the start-up process of combustion engines. They produce a battery-like output direct voltage (24VDC) with low residual ripple. Our mains starter devices are also protected by thermal switches to ensure safe operation.

If an ELTRA mains starter device is used instead of a starter battery, a combined heat and power plant, for example, can be started in a more environmentally friendly way, with less maintenance and with better starting behavior, as a higher starting speed is achieved. This enables a safe engine start, especially in colder ambient conditions.

We manufacture our mains starter devices for engine power from 3.5 kW to 30 kW. As standard, the mains starter devices are designed with 3x360V-400V-440V on the primary side. You can choose between protection classes IP 00 and IP 54.

We design and implement complete solutions for transformer cabinets, including ventilation and fuses, e.g. for use in projects in the industrial furnace sector. We offer suitable series transformers that can be adapted to country-specific voltage levels. This ensures that your system and the power supply harmonise perfectly. We manufacture suitable chokes and filters designed to reduce interference caused by the drive system. There are (almost) no limits to your wishes.

Our transformers and chokes have been used for many years in large numbers, particularly in the wind energy and photovoltaic sectors. Our product range also includes mains starting devices for combined heat and power plants. We find innovative solutions for our customers that ensure flawless and reliable operation. This is why we manufacture to the highest quality requirements in order to avoid maintenance, repairs or even replacement for our customers.

Get in touch with us about renewable energies and we‘ll work with you to identify the right product for your project so that we can drive the energy transition forward together.

We manufacture complex high-current transformers with attached rectifiers, air- or water-cooled.
For example, these are used in annealing or heating processes, in galvanising and in resistance welding systems.
