Control and monitoring unit for VBCS Triple chargers. It displays the status of the individual charging sources, the current charging phase, the voltage of the on-board and starter batteries and the current charging current. In solar operation, the displays for the current solar output (W) and an energy counter for Wh and Ah with reset function are also available. The mains charging mode of the VBCS Triple can be manually switched on or off or reduced in power (AC power limit) at the touch of a button, e.g. when the shore power connection is weakly fused. A special protective function ensures that an accidentally switched off mains charge is reactivated if the on-board battery runs the risk of being deeply discharged. The large, clear display has a white illuminated and easy to read graphic display with very low power consumption. The device can also be easily retrofitted at any time via the Plug and Play connection and matches the Votronic modular system in terms of design and construction.
