SPM Module Descriptions

SPMA - Is a complete inverter drive (AC in, AC out) with internal rectifier capable of being parallel connected with SPMA modules of equal rating. DC connections are present for regen and common bus applications.

SPMD - Inverter module (DC in, AC out) that requires a DC power supply from either an SPMC/U or an existing source.

SPMC - Controlled rectifier bridge module (AC in, DC out) used as a front end power supply to the SPMD inverter module.

SPMU - Uncontrolled rectifier bridge (AC in, DC out) used as a front end power supply to the SPMD inverter module. A separate soft start must be provided.
