Transformers: Product of entrepreneurial birth

BLOCK Complete portfolio at Bürklin Elektronikk

The origins of BLOCK lie in the production of transformers, which play an important role as essential components in technical processes and are used primarily to adjust voltage levels in applications. Transformers not only enable the creation of new network forms, but also ensure permanent adaptation of downstream equipment to the required voltage level, regardless of operating conditions.

With his extensive standard portfolio of mains, control, safety, isolating and autotransformers, BLOCK always offers the perfect choice for individual system design. The products are the ideal choice for a reliable and functional solution.

Top products from BLOCK: Voltage transformers, power supplies, circuit breakers and wires

Universal helper for overload - USTE 1600/2x115

The USTE series control transformers are specially designed to provide universal voltage matching and isolation of input and output circuits. In addition, they also meet the stringent requirements of the safety and isolation transformers.

The USTE 1600/2x115 offers numerous features and advantages: It has low inrush current and offers safe galvanic isolation. It also has a universal input voltage range and BLOCKimpex vacuum impregnation, which provides excellent corrosion protection. With low noise and push-in terminals for quick wiring, it is extremely user-friendly. It can also be mounted on mounting rails, thanks to the combined footplate that supports up to 250 VA. The wide input voltage range of 208 V - 600 V and UL Listed approval complete the overall package.

Maximum supply with minimum space requirement - PCC-0124-100-2

The Power Compact Champ (PCC) from BLOCK are universal single-phase power supplies suitable for a wide range of applications and industries. With their compact design and robust electrical and mechanical nature, they meet all requirements. In the event of high starting or inrush currents, up to 150 % is available for 5 s and 110 % is available permanently as a static power reserve. The high efficiency of the PCC contributes directly to reducing energy costs and CO2 emissions in every application. Thanks to their compact design, they save space on the DIN rail and can be used in space-optimized control cabinets.

The PCCs offer numerous advantages, including high reliability and service life, high efficiency and compact design. They are protected against shock and vibration as well as transient mains overvoltages. They also have a wide range of safety standards and approvals and meet the latest EMC standards. The PCCs are a best-in-class solution.

Selective fuse protection of DC circuits - PC-0724-800-0

The Power Compact circuit breaker in the Economy Smart version with thermomagnetic tripping characteristic is an excellent alternative to conventional miniature circuit breakers. It offers safe tripping, even with high line resistances, and is perfectly suited for use in device and series machine construction. The circuit breaker has 8 channels, which allow for a small overall width and thus free up space in the control cabinet.

Outstanding features and benefits of the Power Compact circuit breaker include its ability to reliably switch on high capacitances (>50,000 mF), the ability to diagnose and remotely switch channels via two lines, an adjustable rated current per channel, a remote reset contact, and a summing alarm contact for easy remote diagnostics. In addition, the circuit breaker can switch channels sequentially and load-dependently.
