Description
Preserves starting battery voltage by isolating the auxiliary
battery when system voltage drops. For vehicles with two
batteries (or banks of batteries). Turns any electromechanical
solenoid or relay into a Smart Isolator.

Features and Benefits
• Isolates main and auxiliary batteries when system voltage
drops below 12.7V, and automatically reconnects battery
banks at 13.2V. Preserves starting power; eliminates
downtime and jump starts due to dead batteries.
• Start assist feature provides boost to starting battery,
when needed.
• Compatible with modern electronically controlled
alternators (some diode Battery Isolators are not). Smart
Battery Isolator Controller eliminates false battery
warnings created by diode isolators.
• Status light output drives remote light, informing operator
when banks are connected.
• Auto-ranging to automatically sense the voltage of the
system (12 or 24V) and selects the presets appropriate to
that voltage.
• Waterproof, dustproof and vibration-proof. Sealed to IP67
so it can mount on a vehicle even in places where roadsplash
is a problem.
• Ultra low 1mA standby current means minimal battery
drain – especially valuable when vehicle is in storage or not
in use.
• Factory programmable unit is highly versatile: with a broad
range of presets available to match any special application.
• Rated for more than 1,000,000 on-off cycles – unit
operates for the lifetime of the vehicle. Solid state
technology gives long life and low maintenance.
• Compact design (4 x 3 x 1”) – Uses less space; mounts
outside or inside. Saves money by eliminating other
hardware, and provides better wire routing.
