Ultra Compact MOSFET Inverter Platform

SKAI 3 LV is the 3rd generation of industrial MOSFET inverters and constitutes the 7th generation of MOSFET inverter technology manufactured by SEMIKRON, with more than 1.5 Million MOSFET inverters in the field. The 3rd generation is a platform concept that offers standard design versions or can be customised to meet your needs. The converter connects easily to a customer control board for quick and easy designing, while leaving the control to the customer.
