Description
SURE POWER 70 Amp 2-Alternator/2-Battery Battery Isolator – 2702
The Sure Power 2702 Battery Isolator is designed for charging systems with two alternators and two batteries. This solid-state isolator allows current to flow from the charging sources to the battery banks while preventing reverse current flow between batteries, helping protect the starting battery from being drained by auxiliary loads.
- Designed for 2-alternator, 2-battery charging systems
- 70 amp maximum alternator rating
- Solid-state design with no moving parts
- Helps prevent battery-to-battery discharge
- Allows each battery bank to charge automatically according to demand
This isolator is suitable for negative-ground DC charging systems where two battery banks need to remain electrically isolated while still receiving charge from the alternators. It is commonly used in marine, RV, service vehicle, and commercial equipment applications.
