Voltage Sensitive Relay Smart VSR Dual Isolator 12V 140Amp Caravan RV

Packing Included:
voltage sensitive relay (VSR) *1; screw * 4; manual *1

Features
A voltage sensitive relay (VSR) is the best way to ensure you can always get your dual- vehicle started.
If the radio stops working that’s one thing, but if you’re stranded because your car cannot start because you
ran your fridge for too long, that’s potentially a life and death scenario. It allows two batteries to be charged
from your alternator. Once your main starter is sufficiently charged, it will begin charging the second too.
Fully automatic with emergency override.

Automatically combines two batteries when charging and isolates the two batteries when not charging.
No voltage drops comparing to isolator diodes (0.6V).
Dimensions fits Heavy Duty Modular Fuse Box Series (BF43x) and Switch, matching mainstream products in market

Built-in LED indication (ON when VSR engages)
Port for remote LED indicating VSR status (LED not included)
(If the VSR is installed in a place that is difficult to see,
it can be installed by an external indicator light, installed in a place that the operator can easily see,
such as the instrument panel, and the negative pole of the external light is connected to the black line to be cut on the VSR .)

Surface or panel mount options provides flexibility when installing
Optional Storage Mode allows zero consumption when engine is off.
（When you do not need this device (VSR) function, you can cut off the red line and connect an ON-OFF switch to control the device's off.
Normally, if the boat or yacht is not used for a long time, turn off the VSR to achieve zero consumption when it is not used for a long time)

Functional Features Example:
After the engine stalls, the left House discharges to the upper left load device,and the VSR disconnects when the voltage drops below 12.8V.?
The Start on the right will not discharge to the device
When the on your left is not charging, it is used up.
At least there is a little on the right that allows you to start the engine
