Lighting transformer with remote control

— Innovation in light and lighting control —

With our patented lighting technology, we have been setting standards in the field of individual lighting composition since 2016. This technology is now built into all of our quiet and flickering lighting transformers for cribs, light houses and dollhouses.

— 5 outputs individually adjustable —

With our latest product, model 07-427.0, all outputs can be set individually using a remote control. With our innovative lighting technology there are many realistic types of light to choose from - ideally matched to light bulbs or LEDs. Many other functions, such as a toy mode, different types of timers or functions for backlighting enable the perfect illumination of individual pieces.


Visit us at the PCIM 2019!


This year, we are again represented at the international trade fair for power electronics. Steger presents its products and competences at the PCIM Europe in Nuremberg. Our focus is on high voltage on small space.

See SMD and PTH isolation transformers for gate-drivers (IGBT, MOSFET) and other applications:

  • SMD up to working voltage of 2 kVpeak
  • PTH up to working voltage of 5 kVpeak

Low leakage, low coupling capacitance, individual ratios.

Hall 6, Booth 202

We are looking forward to your visit!


Highlight 2016

Teilentladungsfreie Übertrager für den Mittelspannungsbereich

The main focus of the PCIM 2016 are partial-discharge pulse transformers and transformers for the medium voltage range for smaller power transfer. Application areas are for IGBT drivers, control and measuring systems and general high voltage applications. Highlight is the presentation of compact pulse transformers with UTEA > 30 kVRMS for power applications greater1000 VA.

Highlight 2015

At the PCIM Europe 2015 Steger presents ultra-compact coils (half chamber RM10) with UTEA > 11 kVDC. The special feature is the small size with a high voltage insulation. Excellent cross sections of the winding and subsequent processing enable the production of such products.

Isolation transformer for energy transfer

Products > Transformers > Isolation and drive transformers

wickelgueter_luftfahrt.jpg On the PCIM 2015 and 2016 our isolation transformers have been of great interest. Since 2016, we have been supplying customers in the energy sector in series production for the first time.

High partial discharge resistance (TEA> 1.5 kVeff) combined with the desired parameters (inductance, coupling capacity, transmission ratio, power) paired with 100% quality and long-term experience from aviation. Performance that convinces.

Top Quality 2014-2016


b_71_80_16777215_00_images_stories_qualitaet_bsh_2013.jpg Also in the years 2014, 2015 and 2016 we were awarded by B/S/H with 0ppm for the highest quality.

Our other awards and certificates can be found in the section Quality.
