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

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

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

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

Future Winding edgewise winding technology, designed by BLOCK, 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.

HF1P filters eliminate harmonic currents and compensate reactive power efficiently in single phase applications. Reliability and lifetime of loads, like energy-saving bulbs, IT power supplies and drives will be drastically increased.

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 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.

The MR3 motor reactors reduce overvoltage spikes and reflected wave phenomena in order to protect the motor. The MR3 series is engineered for a wide-spread installation in order to provide the best in class protection.

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.
