Electric Smart Switch for 48 V, 470 V and 810 V
This smart semiconductor-based switch developed by KYOCERA AVX (Salzburg) ensures a fast, safe, and noiseless switching of DC networks. This is available as a standard module or also as a customer-specific design.
Due to high requirements and increased integration of additional safety-relevant features in the vehicle electrical system architecture, a semiconductor-based solution can provide marked advantages when compared to a mechanical relay, including considerably higher switching speeds. Particularly in the event of a short circuit, every microsecond counts in order to guarantee a safe disconnect. The Electric Smart Switch protects the supply circuit during charging and discharging bi-directionally in the event of overcharging or a short circuit. In addition, the Electric Smart Switch permits the pre-charging of the DC network to enhance the service life of system components.
