DC PROTECTION FOR 19" RACKS


DECENTRALIZED SYSTEM SOLUTION IN IP65 ENCLOSURE

This custom system solution combines high reliability, IP65 protection, and complete pre-assembly in a single enclosure. The redundant 24 Vdc/20 A power supply is provided by two separate switched-mode power supplies connected via a redundancy module, ensuring maximum availability. An integrated capacitive UPS based on supercapacitors secures the 24 Vdc supply in the event of a main power failure, preventing system downtime. The individual load circuits are monitored and protected by an 8-channel electronic circuit breaker. All connections are implemented using high-quality IP65 connectors integrated into the enclosure. An optional interface for condition monitoring and power supply diagnostics is available. The solution is robust, low-maintenance, and designed for use in demanding, decentralized industrial environments.

READY-TO-CONNECT POWER SUPPLY FOR ROTOR CONTROL

Used in the field of power quality, this product solution serves as a power supply for blade pitch control in wind turbines. The drive system allows the rotor blades to be adjusted to the optimal angle relative to wind direction. As a result, overall system efficiency is maximized while mechanical stress is reduced. By integrating this system solution, our customer has achieved precise control of its renewable energy system, increased energy output, and reduced maintenance requirements.

Together with the customer, a plug-and-play solution was developed. Thanks to pre-assembled cables and connectors, the system can be installed easily and quickly and is ready for operation.

GRID CONNECTION SOLUTION FOR LARGE-SCALE STORAGE SYSTEMS IN A 19" RACK

In close cooperation with our customer STABL, we developed an innovative grid connection box featuring an EMI filter and reactor – customized within a specially adapted enclosure. This solution is used in large-scale energy storage systems. STABL’s inverter technology sets new benchmarks in future-ready performance and offers clear advantages over conventional solutions. Together, we are advancing renewable energy and creating sustainable, future-proof storage solutions. 

The grid connection box has a power range of 75 kW. Due to the modular design of the storage system, multiple boxes can be integrated into a single battery storage unit. The reactor and EMI filter ensure reliable and interference-free grid connection.


COORDINATED COMPONENTS AND MAXIMUM LINE PROTECTION TO PREVENT POWER DISTURBANCES


Thanks to its design and attenuation characteristics, the BLOCK EMI filter is specifically adapted to the system requirements and therefore ensures reliable reduction of high-frequency interference. The reactor further reduces line feedback and increases overall system stability.

Our customer STABL receives a customized system solution consisting of a jointly developed sheet metal enclosure with an integrated EMI filter and a reactor. The powder-coated front panel highlights the high manufacturing quality and the appealing design.

THE STABL SOLUTION AT A GLANCE 

  • Customer-specific development of a 19" rack with integrated BLOCK reactor and a BLOCK EMI filter
  • The grid connection box ensures compliance with EMC limits and smooths the voltage
  • Modular multilevel converters for battery storage systems replace conventional battery inverters

330 KVA AUTOTRANSFORMER INTEGRATED INTO A COMPACT MOBILE ENCLOSURE

Together with one of our customers, we developed a precisely controllable 330 kVA autotransformer integrated into an enclosure. The single-phase autotransformer converts a primary voltage of 110 Vac at 3022 A to the required voltage. Via remote control using a PLC or a key switch, different voltages can be selectively applied to the output busbars. Integrated into a robust IP23 enclosure with a total weight of 2.4 tons, this product is one of the largest in our portfolio and is engineered for demanding test applications.
