Siemens C98043-A7002-L4-12 Power Interface Module

Siemens C98043-A7002-L4-12 is a SIMOREG power interface board designed to feed the drive electronics of Siemens DC motor drives, serving as the power interface between the backplane and the power stage. The unit is a spare-part version of 6RY1703-0DA02 and is sold as a complete module that includes terminals, with an approximate shipping weight of 2 kg. It accepts either three-phase input in the 380–460 V range (nominal 400 V) at up to 1 A, or single-phase input in the 190–230 V range at up to 2 A; internal protection on the module is provided by F1 and F2, while an external protective device rated up to 6 A (type C) is recommended. If the incoming voltage falls outside the stated tolerances, a transformer may be required to adapt the supply.
