The maritime industry is known for its rigorous safety and performance standards within electrical systems. From the machine room to the bridge, ensuring a reliable power supply is crucial. Weidmüller offers a comprehensive range of products, fully approved by nearly all shipbuilding classification bodies. Such as DNV (Det Norske Veritas), BV (Bureau Veritas), and RINA (Registro Italiano Navale).
Why Maritime Applications Require Specialised Solutions
Maritime environments demand more from electrical components than typical industrial settings. High vibration, salt spray, and other harsh conditions mean that even high-quality industrial components may fall short at sea. Weidmüller addresses these challenges with their PROtop power supplies and maxGUARD control voltage distribution systems.
PROtop Power Supplies offer high performance and built-in redundancy
Redundancy is essential in marine electrical systems to ensure safety and reliability. PROtop power supplies feature integrated MOSFETs (ORing MOSFETs) for direct parallel switching and eliminate the need for separate diode modules. Overall, this design reduces system costs, saves space, and ensures safe operation by allowing redundant configurations without additional wiring.
Key features of PROtop power supplies include:
- High Efficiency up to 95.5% optimal energy use.
- Dynamic Current Limiting to provide high impulse reserves of up to 600% for 15 ms to reliably trigger circuit breakers, and up to 300% for 100 ms for powerful motor starts.
- Corrosion resistant coated circuit boards offer protection against salt spray.
- Vibration withstands up to 4 g, ideal for use in machine rooms.
- Communication modules for IO-Link and CANopen are available for condition monitoring and integration into control systems.
maxGUARD efficient and reliable control voltage distribution
maxGUARD combines load monitoring and distribution into a single solution, saving almost 50% of space and 20% of wiring work. Designed specifically for the challenges of marine applications, maxGUARD offers selective monitoring of load circuits. Thus, ensuring only the affected circuit is switched off in case of an error.
Key features of maxGUARD include:
- Selective load monitoring to quickly isolate faults and reduce the risk of malfunctions.
- Electronic Fuses for improved reliability and faster reacting than traditional circuit breakers. Individual fuses have two-pole relays for 24 V systems.
- Corrosion resistant protective coatings on components and circuit boards to withstand harsh marine conditions.
- Ease of Servicing due to integrated test contacts and disconnecting levers allow for faster troubleshooting and maintenance.
A system for every situation
Weidmüller’s PROtop and maxGUARD product families offer a versatile, combinable solution that meets high EMC requirements on the bridge. Moreover, they can withstand the harshest conditions in the engine room. Additionally, two UPS control devices and five VRLA battery modules are available. All have DNV and BV approval to ensure uninterrupted power for critical systems during network outages.
