Detailed description

The CLSTR BAT SW 275AX3 & DVSR SQ MC8 by BEP is a battery distribution cluster designed for single-engine marine systems with two battery banks. This integrated system optimizes onboard power management by combining a robust 275-amp continuous battery switch and a digital voltage sensing relay (DVSR).

Electrical Performance and Safety

This cluster provides 275 A DC continuous current, 455 A DC intermittent current, and 1250 A DC cranking current, ensuring reliable power for demanding applications. Its maximum 32 V DC voltage is compatible with 12 V and 24 V systems, while the 2 x 10 mm (3/8") tinned copper termination studs ensure robust connectivity and optimal conductivity. The CLSTR BAT SW 275AX3 & DVSR SQ MC8 is UL 1107 certified and ignition-protected, offering enhanced safety in marine environments. Its minimal power consumption (15 mA in off position) preserves battery charge.

Integration and Advanced Features

The integrated digital voltage sensing relay (DVSR) automatically manages battery charging, prioritizing the starter battery before charging the house battery bank. This ensures your engine is always ready to start while keeping house batteries charged. Installation can be flush-mounted or surface-mounted for flexibility. Compared to modular solutions like individual BEP 716-H battery switches (48 V DC), this cluster is an integrated and compact 12/24 V solution, similar to BEP’s MD series clusters (e.g., 80-716-0014-00 for single engines), but with automatic management of two battery banks via DVSR. This integration reduces wiring complexity and space requirements, offering a significant advantage over separate component installations.

Expert opinion

Pol CONIN

Digital Manager

« Optimized management of two battery banks with BEP »

The CLSTR BAT SW 275AX3 & DVSR SQ MC8 from BEP is an integrated energy management solution, particularly relevant for single-engine vessels equipped with two separate battery banks. Its nominal capacity of 275 A continuous (455 A intermittent, 1250 A at start) is adequate for the vast majority of marine applications, and compatibility with systems up to 32 V DC covers 12 V and 24 V configurations. The integration of a digital voltage separator-coupler (DVSR) is a major advantage, automating the prioritization of the start battery charge before the service battery, ensuring essential start reliability. This approach significantly simplifies wiring and configuration compared to installing separate switches and couplers. The 10 mm (3/8") tinned copper studs and ignition protection (UL 1107 certified) attest to a robust and secure design, an indispensable criterion in a marine environment. The compact format and the option for flush or surface mounting provide flexibility for integration in various technical compartments.

Frequently Asked Questions

Need help? Contact us

What is the main function of the BEP 716-SQ-140A-DVSR battery distribution cluster?

This BEP battery distribution cluster is designed for managing electrical power onboard boats. It controls power distribution for a single engine and two battery banks, integrating a battery switch and a dual voltage-sensing relay (DVSR).

What are the continuous, intermittent, and starting DC current ratings of this device?

This battery distribution cluster has the following current ratings:

Continuous current: 275 A DCCurrent intermittent: 455 A DCCurrent starting: 1250 A DC

How can the battery distribution cluster be installed?

The battery distribution cluster can be installed in two ways:

Flush-mountedSurface-mounted

What is a DVSR and how does it work in this cluster?

A DVSR (Dual Voltage Sensing Relay) is a dual voltage sensing relay. It intelligently charges two battery banks (e.g., starter and service) from a single charging source, ensuring the starter battery is always prioritized and the service battery is charged once the starter battery is full, without direct connection.

What are the benefits of remote mounting the battery switch?

Remote mounting of the battery switch offers several advantages:

Reduced cable lengths and sizes to the starter, resulting in significant savings on copper cables.Reduced installation time thanks to shorter battery wiring.Easier access for battery monitoring.

Is this cluster compatible with other BEP systems or labeling?

Yes, this cluster uses the same interchangeable labeling system as BEP standard battery switches, ensuring compatibility and uniformity with other BEP products.

What does "SQ" mean in the product designation "CLSTR BAT SW 275AX3 & DVSR SQ MC8"?

In the product designation, "SQ" refers to the "Square" format of the BEP battery distribution cluster, as indicated in the description "BEP Square Battery Distribution Cluster".

What does "CLSTR" stand for in the product name?

"CLSTR" stands for "Cluster", indicating that it is an assembly or panel grouping multiple battery management functions, such as a battery switch and a dual voltage sensing relay (DVSR).

What type of studs are used for electrical terminations?

Electrical terminations use tinned copper studs, paired with nuts, to ensure good conductivity and corrosion resistance.

Is this product suitable for single-engine boats with two battery banks?

Yes, this battery distribution cluster is specifically designed for single-engine applications with two battery banks, enabling efficient power management and charging.
