SBA1203 is a robust and high-efficient, switch-mode technology battery charger designed specifically for auxiliary start motors batteries in emergency power generators and diesel engine driven fire-fighting pumps. Conceived to be permanently connected to the batteries, take care and keep them permanently at full capacity. It remains operational even in the process of starting the engine. The standard battery charger SBA1203 is calibrated at the factory for lead-acid batteries, however the float voltage can be factory-fitted on request, to fit other types of batteries.
