SBB24050

SBB24050 is a robust and high efficient battery charger and power supply with high frequency switch mode technology.

As battery chargers the SBB24050 is specially designed for emergency generators and diésel engine driven fire-fighting pump starting batteries. Designed to be permanently connected to the battery they continuously monitor the status of batteries and always keep them in peak capacity. SBB24050 battery chargers remain operational during the engine start process.
