Kussmaul Auto Charge® 11 Series

Dual Battery Banks
Power for Onboard Electronics. Front Panel Amp Meter.

The Kussmaul Electronics Auto Charge® 11 series consists of heavy-duty, fully automatic, dual-bank battery chargers designed explicitly for emergency fleet and specialty vehicles utilizing dual-battery systems. The core system contains two completely independent charging circuits that prevent parasitic electrical loads on one battery bank from draining or impacting the adjacent bank. 

• Independent Sense Processing: Standard and High-Output units dynamically proportion the maximum available charging profile (either 10A or 20A) to whichever battery bank exhibits the higher capacity demand.
• No Water Boil-Off: Automatically terminates active power delivery when the battery banks achieve full charge, entirely eliminating trickle-charge overcharging risks to preserve electrolyte levels.
• Parasitic Load Support: Automatically assumes the electrical demand of downstream on-board DC apparatuses (radios, diagnostic electronics, scene lights) without drawing down the actual battery reserve.
