220V–24VDC Distribution Panels: Safe and Reliable Low Voltage Power for Marine Systems

Modern ships require both high and low-voltage power systems to support a wide range of onboard operations. While 220V AC powers most equipment, 24V DC is crucial for essential low-voltage systems such as automation, alarms, navigation, and communication. At Serden Ship Supply Marine Electric & Electronics Ltd., we provide 220V–24VDC Distribution Panels designed for safety, efficiency, and compatibility with demanding marine environments.

Our panels ensure stable DC power distribution across all essential systems, with advanced protection, monitoring, and compliance features tailored for marine applications.

 What is a 220V–24VDC Distribution Panel?

This type of panel converts and distributes low-voltage DC power across various shipboard systems. It typically takes 220V AC input—sourced from the main or emergency switchboard—and converts it into regulated 24V DC output through a dedicated rectifier or power supply.

From there, power is routed to:

• Navigation and bridge equipment

• Fire alarm systems

• Emergency lighting

• PLCs and automation systems

• Communication and radio units

• CCTV and security systems

• Battery chargers and UPS systems

These panels are crucial in maintaining continuous operation of safety-critical and automation systems, especially during emergencies.

 Technical Features of Our Panels

Serden panels are designed to meet the unique demands of marine use:

• 220V AC input with surge protection

• 24V DC output with overvoltage and short-circuit protection

• Marine-certified circuit breakers (MCB/DC MCB)

• Redundant power supply options (dual-input or battery backup)

• Digital or analog voltage and current meters

• LED indicators for each circuit

• DC ground fault detection modules

• Isolated and labeled terminal blocks for easy maintenance

• Internal busbar design with proper clearance and insulation

All components are housed in IP54 or IP65-rated enclosures with corrosion-resistant coating.

 Panel Configuration Options

We offer both standard and custom-configured panels, including:

• Wall-mounted or standalone enclosures

• 6, 12, 18, 24, or more DC output circuits

• Options for battery input/output routing

• Load sharing and current limiting modules

• Diode ORing for redundant power paths

• Integration with Alarm Monitoring System (AMS)

 Key Applications Onboard

24VDC power is used in nearly every system that requires stability and continuous operation, including:

• Fire detection and suppression systems

• Engine room monitoring and sensors

• Control panels (rudder, ballast, tank level, etc.)

• Emergency communications

• Alarm and status indicators

• Navigation lights and searchlights

• Door control and security access

We ensure that every system receives clean, uninterrupted DC power—filtered, fused, and safely distributed.

 Advanced Features (Optional)

For clients requiring higher functionality, we offer:

• Digital circuit monitoring via HMI or web interface

• Remote diagnostics via Modbus TCP/RTU

• Battery condition monitoring

• Data logging for current, fault, and voltage drops

• Breaker trip alarms integrated with bridge panel

These features help engineers and ETOs perform predictive maintenance and identify faults in real time.

 Compliance & Classification

Our 220V–24VDC Panels are built to comply with:

• IEC 60092-504 (marine electrical installations)

• IEC 60947 (low-voltage switchgear and control gear)

• IMO SOLAS regulations for emergency systems

• Classification societies: DNV, ABS, RINA, BV, ClassNK, Lloyd’s

Every panel is delivered with:

• Factory Acceptance Test (FAT) documentation

• Electrical drawings and terminal schedules

• Component datasheets and conformity certificates

• Maintenance and operation manuals
