Catalogs and brochures

The compact and clearly structured catalog with the BLOCK DIREKT range. Over 1,200 products from the divisions of transformers, power supplies, reactors, and EMI filters can be delivered within 24 hours.

Our wide standard range of BLOCK power, control, safety, isolating and autotransformers provides you with the right choice when building your systems.

Switched mode power supplies, electronic circuit breakers, uninterruptible power supplies, redundancy modules, and accessories for the reliable supply of your systems.

Maximum system availability, strong and flexible in any application, yet light and compact – our new Power Compact Champ power supplies.

EasyB – The modular, 24 V circuit breaker system for the reliable fusing of the 24 V control voltage level. Can be extended flexibly and for communication.

Future Winding edgewise winding technology, designed by BLOCK itself, enables a new dimension of power optimization of inductive winding products.

Not only does the new SF4 all-pole sine filter series solve a host of such EMI problems, it also increases the efficiency of drive systems controlled by frequency converters.

One of a kind: Our new push-in terminal offers numerous convincing advantages. Whether it‘s simple handling or time savings during assembly – it makes a significant contribution to increasing efficiency and safety.

Inductors and transformers for the medium frequency range represent a dynamic field for development. New materials and technologies have enabled innovative steps on a continuous basis over recent years.

Robustly tested technologies are demanded in railway technology. BLOCK's custom-made railway products are characterized by exceptional properties for use in railway technology. Reactors. filters and medium-frequency transformers tested in line with EN 60310 and EN 45545 HL3 and developed according to the latest industrial standards.

The new image brochure for the 80 years jubilee of our company.
Interesting facts about Block, the last 80 years and the exciting shaping of the future.

The BIG BLOCK, the complete standard portfolio with more than 2500 products of transformers, power supplies, reactors and EMI filters.

The CT series of control power transformers from BLOCK as an economic solution for general and industrial applications. Robust and flexibly enhanceable with a TS35 rail or US fuse holder.

For the reliable protection of the system, the use of isolating transformers with galvanic isolation between the windings is ideal. TT3 Neo isolating transformers provide secure isolation at high power ranges from 10 kVA to 1 MVA.

Choking with the DR3 detuned reactors from BLOCK broadly rules out the risk of overcurrent through resonance, thus ensuring optimal protection of the compensation capacitors, and an improvement in voltage quality.

A selection of inductive components for power electronics. Main transformers, current-compensating reactors, DC reactors, and drive transformers benefit from BLOCK's comprehensive development and production competence.
