Centaur 12/30(3) 120-240V - Battery charger 12V 30A
Centaur 12/30(3) 120-240V is a 12 V, 30 A battery charger with an auto-ranging 90-265 V AC, 50/60 Hz input that maintains full output across the whole range, so it can be used anywhere in the world. Automatic three-stage (IUoU) charging and three isolated outputs suit multi-battery installations, with a recommended capacity of 120-300 Ah.
Main features:
- Charge output: 12 V, 30 A
- Isolated outputs: 3, each capable of full rated current
- AC input: 90-265 V, 45-65 Hz
- Charge algorithm: IUoU three-stage, temperature compensated
- Absorption / float: 14.3 V / 13.5 V, DIP switch for flooded, Gel or AGM
- Recommended capacity: 120-300 Ah
The Centaur range of battery chargers features auto-ranging input covering 90-265VAC 50/60Hz input meaning they can be used anywhere in the world.
Crucially, and unlike many other products that state universal input, the Centaur range will maintain full output power within the entire specified range. Other features include fully automatic three stage charge characteristic that ensures batteries are fully charged every time and three isolated charge outputs for multi battery configurations to suit the majority of typical installations.
The range spans 12V and 24V models from 16A through to 100A.
