Product Brief Description

The Allen-Bradley 80026-529-01-R is a 1000W single-phase AC/DC power supply unit designed exclusively for Rockwell PowerFlex 7000 medium voltage variable frequency drives. It supplies stable auxiliary power to the internal control circuits, gate drive boards and monitoring subsystems of the MV drive. This discontinued industrial power unit features rugged construction for heavy-duty power plant and mining environments, widely used as spare replacement part for existing PowerFlex7000 installations.
