Technical Specifications
Main Features and Advantages
The SIME-STROMAG 4205 Electric Power Supply unit is packed with features designed to provide superior control, safety, and efficiency for industrial braking systems.
Progressive Release Capability: A standout feature of the 4205 is its ability to provide a progressive release of the associated electromagnetic calipers. This allows for controlled and smooth lowering operations, moving from 100% to 50% of the nominal braking torque. This precise control is crucial for applications requiring delicate load handling or controlled descent, minimizing shock and wear on mechanical components. It can be controlled manually or through a regulated closed-loop system using speed feedback, providing versatile operational modes.
“Economic Mode” for Energy Efficiency: The SIME-STROMAG 4205 incorporates an “economic mode” that, once the brake calipers are open, reduces the electrical consumption and heat generation of the electromagnetic brakes. This intelligent feature not only translates into significant energy savings but also extends the lifespan of the brake coils by preventing excessive heating, leading to lower operating costs and reduced maintenance.
Fast Opening and Closing Times: The 4205 is engineered to ensure rapid opening and closing times for fail-safe electromagnetic brakes. This quick response is vital for emergency stop situations, ensuring that the braking force is applied promptly when required, thereby enhancing overall operational safety. A high “call” voltage typically contributes to reduced opening response time.
Robust Protection and Reliability: Equipped with comprehensive overload and over-current protection, the 4205 safeguards both itself and the connected braking system from electrical anomalies. This robust protection, combined with a durable design (often available in polycarbonate or steel enclosures), ensures reliable and high-performance operation even in harsh industrial environments, contributing to system longevity and reduced downtime.
Seamless Integration with SIME Brakes: The 4205 is specifically designed to work in conjunction with various SIME Brakes electromagnetic emergency brake types, such as the SA range (OSA, OOSA, 2SA), 3CA2, and 4CA2. This ensures perfect compatibility and optimized performance, forming a complete and highly efficient braking solution from a single, trusted manufacturer.
Enhanced Safety for Lowering Operations: The unique progressive release capability, especially when combined with options like manual lowering with a dead-man safety device or overspeed safety, significantly enhances the safety of load lowering operations. This prevents uncontrolled descents and provides operators with precise control, minimizing risks in critical lifting and handling applications.
Application Field
The SIME-STROMAG 4205 Electric Power Supply unit is a critical component in a wide range of heavy-duty industrial applications where precise control, safety, and energy efficiency of electromagnetic braking systems are paramount. Its unique progressive release feature makes it particularly valuable for operations requiring controlled load lowering.
In the steel industry, the 4205 is widely used in overhead cranes, ladle cranes, charging cranes, and scrap cranes. These applications demand robust braking solutions for safely handling extremely heavy and often hot loads. The progressive release capability of the 4205 is crucial for precise positioning and controlled lowering of ladles or materials, enhancing both safety and efficiency in the challenging steel-making environment.
For port and marine applications, including container cranes, ship loaders, and offshore winches, the 4205 ensures safe and controlled braking and lowering of cargo. The ability to precisely manage descent rates is vital for preventing damage to goods and equipment, especially in dynamic marine conditions or when high lifting speeds are involved.
In nuclear power plants, where safety is of the utmost importance, the 4205 is integral to braking systems on nuclear cranes and other critical lifting equipment. Its reliability and precise control features contribute to meeting stringent safety requirements for handling sensitive materials and equipment.
The mining industry utilizes the 4205 in applications such as large conveyors and hoisting systems where controlled braking and lowering of heavy loads are necessary. The harsh environmental conditions in mines necessitate the robust construction and reliable performance offered by the 4205.
Beyond these sectors, the SIME-STROMAG 4205 finds application in various mass transport systems, theatre winches for stage automation, and other general industrial lifting and handling equipment where fail-safe electromagnetic brakes are employed, and precise, controlled lowering operations are required. Its “economic mode” also makes it an attractive choice for energy-conscious operations across all these fields.

Installation and Maintenance
Pre-installation preparation: Before installing the SIME-STROMAG 4205 Electric Power Supply unit, ensure that all power to the braking system and associated machinery is completely disconnected and locked out, following stringent safety protocols. Select an appropriate mounting location for the 4205 within a control panel or enclosure that provides adequate ventilation and protection from environmental contaminants, moisture, and excessive vibration, as per Stromag’s specifications. Verify that the electrical supply voltage and current capacity match the requirements of the 4205 and the connected electromagnetic brake coils. All wiring must conform to local electrical codes and the manufacturer’s schematics, ensuring correct polarity and secure terminations to prevent electrical faults or signal degradation. Ensure that the electromagnetic brake (e.g., SA range caliper) that the 4205 will control is correctly installed, aligned with its brake disc, and properly wired. Familiarize yourself with the wiring diagrams and any specific configuration settings for the 4205 prior to beginning installation.
Maintenance recommendations: Maintenance for the SIME-STROMAG 4205 primarily involves regular visual inspections and ensuring optimal electrical and environmental conditions. Periodically inspect the 4205 unit and its wiring for any signs of physical damage, corrosion, loose connections, or discolored terminals, which could indicate overheating. Ensure that the enclosure or panel where the 4205 is mounted remains clean and free from dust, debris, and moisture, as these can impede cooling and lead to electrical issues. Verify that the “economic mode” is functioning correctly, reducing power consumption when the brake is released. While the 4205 is designed for high reliability, it’s crucial to also conduct routine inspections and maintenance on the electromagnetic brake calipers it controls, checking for lining wear, proper air gap, and smooth operation, as issues with the brake itself can impact the 4205‘s performance or trigger its protective features. In case of a malfunction, consult the SIME-STROMAG technical manual for troubleshooting guidance and consider professional service if complex repairs are required.
