Kongsberg BS610 Battery Supply Unit

The Kongsberg BS610 is a high-integrity battery supply unit designed to provide uninterrupted 24 V DC power to critical marine and offshore automation systems. This compact unit integrates a battery charger, power supply, and monitoring functions into a single module, ensuring continuous operation of control systems, navigation equipment, and safety systems even during mains power failures.

System Description

The BS610 accepts a primary 24 V DC input from the vessel’s main power system. Simultaneously, it maintains a battery bank (lead-acid or AGM) at full charge using a controlled charging circuit. In normal operation, the load is supplied from the primary input while the battery is kept in a fully charged state. If the primary supply fails, the unit automatically and without interruption transfers the load to the battery. When mains power returns, the load is transferred back and the battery recharges.

Electrical Specifications

• Input voltage: 24 V DC nominal (20 to 32 V DC)

• Output voltage: 24 V DC regulated

• Output current: 10 A continuous

• Battery charging current: adjustable up to 5 A

• Battery types: lead-acid, AGM (12 V or 24 V configuration)

• Switchover time: less than 1 ms, no output interruption

Battery Management

The BS610 incorporates a microprocessor-controlled charging algorithm that ensures optimal battery life and performance. Features include:

• Three-stage charging: bulk, absorption, and float

• Temperature compensation to prevent overcharging

• Automatic detection of battery connection and condition

• Deep discharge protection to prevent battery damage

• Battery test function to verify capacity periodically

Monitoring and Diagnostics

The unit provides comprehensive status information through front panel LEDs and remote relay contacts. Monitored parameters include:

• Primary input present

• Battery voltage and charge status

• Output voltage healthy

• Battery fault (low voltage, high impedance, or disconnected)

• Charger fault

Remote monitoring is facilitated by potential-free relay contacts that can be wired to the vessel’s alarm system or automation controller.

Physical Construction

The BS610 is housed in a robust metal enclosure suitable for marine environments. It is designed for mounting inside control cabinets or on DIN rails. The unit includes protective covers for terminal connections and clear labeling for all electrical connections. Ventilation is provided through the enclosure, and no forced cooling is required under normal operating conditions.

Applications

The BS610 is ideal for ensuring uninterrupted power to:

• Engine control and monitoring systems

• Navigation and communication equipment

• Alarm and safety systems

• Automation controllers and I/O modules

• Emergency lighting circuits

• Instrumentation and sensors

Installation and Configuration

Installation involves mounting the unit in a suitable location, connecting the primary power source, load, and battery bank according to the wiring diagram. Charging parameters can be adjusted via internal DIP switches to match the battery type and capacity. The unit is factory-calibrated and typically requires no additional setup. It is recommended to perform a functional test after installation to verify automatic switchover and alarm functions.

Certifications

The BS610 is type-approved by major classification societies for marine and offshore service. It meets applicable standards for electromagnetic compatibility, safety, and environmental protection (temperature, humidity, vibration). The unit is designed in accordance with IEC 60945 for marine navigation and radio communication equipment.

Maintenance

Periodic inspection should include verifying battery condition, cleaning ventilation openings, and testing alarm outputs. The BS610 is designed for long service life with minimal maintenance. Battery replacement should be performed according to the manufacturer’s recommendations, and the unit will automatically adapt to new batteries.

With its robust design and reliable power backup, the Kongsberg BS610 ensures that critical systems remain operational during power disturbances, enhancing vessel safety and operational availability.
