A5S

							A5S series AC motor controller provide advanced control of ACinduction motors and permanent magnetdrive motors performing on-vehicletraction drive or hydraulic pump duties.They offer vehicle developers a highly costeffective combination of powerperformance and functionality.

The A5S series deployed with multiplepatented techniques, that extend life ofbuild-in relays and MOSFET units, a higherreliability is achieved.
