Reliance Electric 701819-14AB Rectifier

Reliance Electric 701819-14AB Rectifier is a compact power-cube rectifier module designed for use in Reliance Electric DC drive systems. Identified by part number 701819-14AB, this unit functions as a single-phase, half-controlled rectifier block that forms the rectifier stage of the drive’s DC power path. Marketed by distributors as a Reliance Electric Power Cube Rectifier, it is intended to integrate with other Reliance components within legacy DC drive assemblies such as the DC1/DC2 family, serving to convert AC input into DC for the drive bus. Typical applications include industrial motor control cabinets and legacy Reliance DC drive installations where modular rectifier blocks are mounted to pair with control boards and power modules. The 701819-14AB designation places it within the broader Reliance power-cube family, offering a compact, replaceable rectifier solution for mid-to-late 20th-century industrial drives.
