Detailed description

The DC BATTERYMNG M 2DUALCIRCPLUS panel from Blue Sea Systems is designed for power management and distribution for two battery banks. It integrates a Dual Circuit Plus battery switch, allowing simultaneous switching of two isolated battery banks or combining them to power all loads.

Power management and safety

This panel includes an automatic charge relay (ACR) that automatically combines batteries during charging and isolates them during discharge. The "make-before-break" design of the switch enables switching between battery banks without interrupting power supply. Starting and house circuits are isolated, reducing the risk of fully discharging both batteries and protecting house electronics from voltage drops or engine start surges. An emergency combine function provides the ability to link both battery banks in case of emergency, for engine starting or radio communication.

Performance and robustness

The M-Series Dual Circuit Plus switch supports a continuous current of 300A, an intermittent current (5 min) of 450A, and a starting current (30 sec) of 675A per circuit. It is designed for a maximum voltage of 32V DC. The panel is rated IP66, providing protection against dust and powerful water jets, making it suitable for marine environments. Tin-plated copper studs ensure maximum conductivity and corrosion resistance. This system is Ignition Protected certified, allowing safe installation on gasoline-powered boats and in engine compartments. It complies with ABYC, UL 1107, UL 1500, and SAE J1171 standards.

Installation and flexibility

The switch housing allows surface, front-panel, or rear-panel mounting. The panel itself is designed for easy integration into modular architectures. Terminals are sized 3/8" - 16 (M10) and require 4/0 AWG cable to meet nominal values.

Frequently Asked Questions

Need help? Contact us

What is the Blue Sea Systems DC BATTERYMNG M 2DUALCIRCPLUS panel?

This is a power management and distribution panel designed specifically for two battery banks. It integrates a Dual Circuit Plus battery switch and an automatic charging relay (ACR) to optimize battery charging and isolation.

What is the primary function of the integrated Dual Circuit Plus switch?

The Dual Circuit Plus switch allows simultaneous switching of two isolated battery banks or combining them to power all boat loads. Its "make-before-break" design ensures switching without interrupting power supply.

How does the automatic charge relay (ACR) function in this panel?

The automatic charge relay (ACR) automatically combines batteries during charging to ensure both banks are recharged efficiently. It then isolates them during discharge to prevent one battery from draining another.

Does this panel ensure circuit safety?

Yes, the panel is designed with isolated start and service circuits, which reduces the risk of fully discharging either battery. This isolation also protects the service electronics from voltage drops or startup spikes from the engine.

What is the DC current rating of the M-Series Dual Circuit Plus switch?

The M-Series Dual Circuit Plus integrated switch in this panel supports a continuous current of 300 amperes.

Does the panel have an emergency start function?

Yes, an emergency combining function is built in. It provides the ability to connect both battery banks when needed, for example to start the engine or power a radio communication.

What is the specific feature of the "make-before-break" switch design?

The "make-before-break" design ensures that the contact is established with the new circuit before the old one is fully disconnected. This guarantees continuous electrical power without interruption when switching between battery banks.

Is this panel waterproof or weather-resistant?

Yes, the Dual Circuit Plus battery switches and integrated automatic charge relays (ACR) are rated IP67. This rating means they are protected against temporary immersion in water and dust.

What is the brand of this battery management panel?

This battery management panel is manufactured by Blue Sea Systems.

What is the reference number (SKU) of this product?

The product reference number (SKU) for this item is 8689-BSS.

What tools are required to install this panel?

For the installation of this panel, the product context mentions the need for a wire stripper, a crimping tool for wire terminals, an electric drill or screwdriver, and screwdrivers.

Does the panel require specific fuses for operation?

Yes, the product context indicates that the nominal fuse ratings are an important aspect for the panel's operation. It is essential to ensure that the correct fuses are used for the system's safety and performance.

Does the panel include a battery charger?

The panel integrates an automatic charge relay (ACR) that provides direct current (DC) charging from the engine alternator, automatically combining batteries during charging.

Are there minimum connection requirements for the panel to operate?

Yes, the product context indicates that minimal connections are required for the panel to function. It is important to ensure that all necessary connections are properly established.

Is the panel compatible with an external battery charger?

The panel integrates an automatic charge relay (ACR) that combines the batteries during charging. If an external charger is connected to the battery banks, the ACR will manage the charge distribution between them.
