DT90 - 2 ISOLATORS IN 1 UNIT

DON’T JUST PROTECT YOUR CRANKING BATTERY,

PROTECT YOUR AUXILIARY BATTERY AT THE SAME TIME

DT90 is $245.00

There are no other types of Dual Battery Isolators that offer anywhere near the operating and charging advantages that our DT90 Isolators achieve.

Our DT90 Isolators will allow you to recharge batteries at up to 6X faster than a DC/DC device

SPECIAL NOTE - The DT90 is perfectly suited for use in new vehicles quipped with STOP/START function.


The DT90 is a very unique Dual Battery Isolator and is the equivalent of having an SC80 and an ABG-25 in one device. Plus you also have an In-Cab Module, used to select different operating functions of the DT90 and displays Battery Capacity.

The DT90 has two separate operations, it first protects the Cranking Battery against being discharged to low that it can’t start your motor. Then the second function is to make sure your accessories can never over discharge and damage your Auxiliary Battery.

The DT90 allows you the user to charge the way these new functions operate, to suit your own personal Dual Battery requirements.


These new features are Selected by using the switches in the In-Cab Module :- 

TIME-OUT =  72 hours ( Pre-setting ), 18 Hours or 15 minutes ( USER Selectable )

BATTERY MONITORING = Both Batteries ( Pre-setting ), Main Only ( USER Selectable )

ACCESSORIES OUTPUT = TIME-OUT ( Pre-setting ), FRIDGE Op ( USER Selectable )

ACCESSORIES LOW VOLTAGE CUT-OUT LEVEL = 11.6v ( Pre-setting ), 10.5v ( USER Selectable )

Toggle  Switch = SHARED Mode ( Pre-setting ), STORED Mode ( USER Selectable )
