Cupă-baterie motorizat 701-MDVS BEP

The 701-MDVS from BEP is a motorized battery switch sensitive to voltage (VSS), designed to automate battery bank management on board vessels. It combines the features of a charge relay and an emergency parallel switch.

Its main function is to automate battery bank management by monitoring their state of charge and protecting them against deep discharges. It also provides an emergency coupling function to link battery banks if necessary.

The 701-MDVS is specifically designed to operate with 12V DC battery systems. Its operating voltage range is 8 to 15V DC.

The 701-MDVS can handle a continuous DC current of 275 amperes, an intermittent DC current of 455 amperes, and a peak starting current up to 1250 amperes DC.

In automatic mode, the system continuously monitors battery voltage. If the voltage drops below 12.2V for more than 5 minutes, the system automatically disengages to preserve the integrity of the starter battery.

The emergency coupling function allows manual or remote linking of battery banks in case of failure, ensuring a backup power source for starting or other critical needs.

The integrated LED indicator provides real-time system status via different light codes:

A rapid flashing (0.1 sec ON / 0.1 sec OFF) indicates voltage out of specification (below 8V or above 15V). A long flashing (5 sec ON / 0.5 sec OFF) indicates that the emergency parallel mode is engaged. A medium flashing (1 sec ON / 1 sec OFF) indicates that the VSS is in low-voltage disconnect mode (voltage below 12.2V/24.4V). A solid LED indicates that the VSS is engaged. An unlit LED indicates that the VSS is disengaged.

The power consumption of the 701-MDVS battery switch is extremely low, drawing only 15 mA when the switch is in the OFF position.

The battery switch is IPX6 certified for water resistance and is protected against ignition per UL 1107 and ABYC/CE standards, making it fully suitable for marine environments.

The 10 mm (3/8") studs are made of tinned copper and the nuts are made of stainless steel. These materials ensure optimal conductivity and excellent resistance to corrosion in a marine environment.

The 701-MDVS is designed to operate reliably in demanding marine environments, with an operating temperature range from -20°C to +60°C (-4°F to 140°F).

Yes, the 701-MDVS is IPX6 certified, meaning it is protected against powerful water jets and can withstand the toughest marine environments.

The mechanical installation of the 701-MDVS is flexible, allowing surface-mount or flush-mount installation depending on your dashboard or battery compartment requirements.

The 701-MDVS is equipped with two 10 mm (3/8") tinned copper studs for power connections, ensuring a robust and reliable connection.

The maximum recommended cable size is 50 mm² (1/0). If using a cable larger than 50 mm², it must be strain-relieved, with an absolute maximum of 70 mm² (2/0).

The recommended torque for the stud nuts is 8 Nm (5.9 lbf) to ensure a secure and optimal electrical connection.

It is imperative that the negative wire (black) of the 701-MDVS be connected to the same battery it is isolating. Only one negative connection must be provided to each unit for correct operation and to avoid any erratic behavior.

Yes, the 701-MDVS can be controlled remotely via a compatible remote switch, providing installation flexibility and ease of use.

To turn the battery isolator on remotely, briefly press the remote switch until the power activates or the LED indicator lights up. To turn it off, hold the remote switch pressed for more than 2 seconds.
