Layout drawing of an IGBT supply unit 1×R8i (limited scope
version)
Limited scope means simplified version of a low power multidrive (400V and 500V) with
less options and configurations. Includes only max 980A DSU, max 810A IGBT supply units
and R1i-R7i inverter units.
Note that there is also another version of 1×R8i supply unit available, see the drawings
below. The multidrive version contains separate auxiliary control and incoming cubicles.
