Catalogs and brochures

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 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.

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

TOGA COLOR is the universal solution for applications in a demanding environment. With a built-in switched mode power supply, inrush current limiter, auto, safety or isolating transformer, closed solutions can be implemented up to protection class IP23.

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.

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.

Compact and robust passive components for the power electronics of the next generation. Medium-frequency transformers, encapsulated PCB transformers, power converters, ferrite storage reactors, and current-compensated reactors. BLOCK inductors for PCBs are available for SiC/GaN.

BG, BGE, and BGUK steel plate enclosure series do not just offer protection against environmental influences. The optimal cooling of the internal components and the flexible adjustment are also in focus.

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.

Copper wires, copper litz wires, resistance wires, sleevings in various designs. Suitable for the manufacture of coils and windings.

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.

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.

PLED drivers are the first choice for the simple switching or dimming of LED lights. Above-average robustness against transient overvoltages, they are especially reliable and durable.

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.

The certified FAIL-SAFE transformer for input voltages of 230 V and 400 V. The primary design of the BLOCK FAIL-SAFE transformers guarantees permanently safe current interruption in the event of short circuits and overloads.
