50A 3 output. Four stage IUoU charge programmed battery charger. These battery chargers especially designed for marine use have a four stage IUoU charge programme.In the first Bulk charge stage the battery receives a continuous maximum current charge. Once the battery is recharged to approximately 75% of its full capacity the charger switches automatically to a constant voltage Absorption stage for the remain.When the battery is fully charged the charger will maintain this charge phase for 15 minutes.(providing the charge is under 6.25 % of the full charge current) and then switches over to the Float. charge stage. In this stage the battery charger maintains the full charge without overloading the battery. It compensates for self-discharge and “floats” any loads on the battery.After being in the float stage for 12 days the charger implements the final Reconditioning stage. In this stage the charger will switch to the Bulk stage for 85 minutes only to ensure that the battery stays in optimum condition.With easy access dipswitches the maximum charge voltage can be adapted to suit the type of battery being charged. These chargers are suitable for all AC power sources from 90 V to 265 V. The active Power Factor Correction feature takes care of any unwanted line disturbances. Vetus battery chargers are extensively tested including a 2G vibration test to meet our quality standards and ensure long term operation. These new chargers are compatible with Lead Acid Li-ion Gel and AGM batteries and can be connected to a remote control panel (BCRP) and a battery temperature sensor (BCTS). The chargers have a separate alarm contact and the fan speed can be adjusted for comfort reasons.A trickle charger with maximum output of 2A is provided on models BC12151 BC12252 and BC12352.
