Rafmagnsskiptari með rafknúnum mótor VSS 12 V 275 A

This is a motorized battery switch with dual functions. It includes a voltage-sensitive relay (VSS) to automatically manage charging between two battery banks, as well as an emergency parallel function (Emergency Parallel) that can be controlled remotely.

This model is designed to handle very high currents:

Continuous current: 275A DC
Intermittent current: 455A DC
Cranking current: 1250A DC

The maximum recommended cable size is 50 mm² (1/0). If you must use a larger cable (up to an absolute maximum of 70 mm² or 2/0), it must be fitted with a strain relief to prevent damage to the terminals.

The device is equipped with two connection studs measuring 10 mm (3/8") in diameter, ensuring robust attachment of power terminals.

Yes, it has an IPX6 waterproof rating. It is fully protected against powerful water jets and breaking waves, making it perfectly suited to demanding marine environments.

The "-D" version of this battery switch is equipped with a Deutsch connector (male DTM06-3S model with 20AWG contacts). This industrial standard ensures a perfectly watertight and vibration-resistant control connection.

Rapid flashing (0.1s on / 0.1s off) indicates two possible situations:

The voltage is out of specifications (below 8V or above 15V/30V).The battery switch is in manual override mode.

This function allows you to manually couple your battery banks (e.g., house and start batteries) if your engine battery is too weak to start. When engaged in this mode, the LED emits a long flashing pattern (5 seconds on, 0.5 seconds off).

If the voltage drops below 12.2V (or 24.4V on 24V systems) while the engine is charging, the LED will flash for 5 minutes. If the voltage does not recover, the VSS relay will automatically disengage to protect your batteries from deep discharge.

Yes, the device is certified "Ignition Protected" (protected against gas ignition). It can therefore be safely installed in compartments containing gasoline engines or fuel tanks.

It can be surface-mounted or recessed. Recommended fasteners are M5 or 3/16" screws. The rear and side panels are removable to facilitate cable routing and orientation.

The operation is very simple:

To turn on: Briefly press the remote switch.To turn off: Hold the switch pressed for more than 2 seconds.

This product meets the world's strictest marine safety standards. It holds CE, ABYC, and UL 1107 certifications.

Only one negative wire (black) must be connected per unit. This wire must be directly connected to the negative terminal of the same battery that the battery switch is intended to isolate.

This specific light signal (3 repeated flashes/beeps every 2 seconds) indicates either the first power-up of the device, or an overvoltage/undervoltage alert detected on the vessel's electrical system.
