  • Dual sensing-senses charge on both battery banks
  • Start Isolation (SI)-can be configured for temporary isolation of House loads from Engine circuit during engine cranking to protect sensitive electronics
  • Engine Isolation (EI)-can be configured for isolation of two engines while both are running to protect engine electronics and maximize alternator output
  • Senses charging on two battery banks
  • LED output to remotely indicate when batteries are combined, isolated, in voltage lockout, or in Start or Engine isolation
  • 3/8"-16 tin-plated copper studs for maximum conductivity and corrosion resistance
  • 7/8" (22mm) stud length accepts multiple cable terminals
  • Silver alloy contacts provide high reliability for switching live loads
