Steca Tarom
Description
The new edition of the Steca Tarom sets new standards in its power class. A graphic display informs users about all of the important system data. These data are stored by the integrated data logger.
Based on the significantly improved state of charge calculation, regulation of the system is optimal and the batteries are protected. The Steca Tarom charge controller is the best choice for larger systems at three voltage levels (12 V, 24 V, 48 V).
Two additional switching contacts can be freely configured as a timer, night light function, for starting generators or as a surplus manager.
