This DC Electronic Switch allows control of power source usage in DC systems with redundant sources (batteries). DCES Digital Controller offers the flexibility of selecting the active source of DC power in a system or periodically switching between sources. The LCD display provides voltage reading for each of the sources. The unit is also equipped with Source 1 On and Source 2 On LED indicators. La Marche has developed two versions of DC Electronic Switch product line; DCES has been developed for utility and other constant type loads (PLC’s, switchgear, monitoring equipment, etc.), and DCESE for engine starting applications with higher inrush current.
